ROIP Gateways: Airport ‘Crashphone’ and Beyond

The Problem

Communicating over a distance has always presented a challenge to humans. From signal mirrors, semaphore flags, and satellites, people have leveraged technology to overcome communications challenges. In my Army days I had radio relay system in my vehicle that took up half the space, so that I could extend the reach of battlefield commanders to their resources. Today, we take speed, availability, and distance for granted with such innovations as cellular telephony, and Starlink. However, in a mission critical environment such as Command and Control (C2), this presents a unique challenge. The communication must be instant, reliable, and able to reach the responders regardless of where they are and what they may be using for communications.  Add to that the need for immediate access to decision makers and experts, and the complications begin to pile up.

How does a dispatcher in an emergency center served via the cloud not only reach their field assets, but the experts and leaders necessary to coordinate a unified response? That dispatcher may be on a console with a Radio over IP (ROIP) interface while the field assets may be on push to talk (PTT) radios, and the experts and leaders who may be travelling and on a cell phone or in conference room located far away in a municipal capital. How does an IT manager securely integrate, provide universal and secure remote access, and archive it for later analysis and compliance? C2 is estimated to be a $45 Billion market with a 6.6 CAGR by 2029. So, solving these problems is not only critical for emergency preparedness, but is a lucrative market for potential vendors.

 

The Solution

Mass notification services have become standard fare for municipal communications. With one call civic leaders can reach all their residents without sirens or public address systems. These can be further integrated with SMS to send the same message via text messaging, email, or other forms of media. In airports, these systems are used as ‘crash phones’ to bring all the airport emergency services and management together on one system rapidly, securely, and independently of the device they use for communicating. This same concept that has served airport management for years will work in other C2 use cases as well.

Imagine the first responder on the scene on a handheld radio, their supervisor enroute in a vehicle, the dispatcher at a console in a command bunker, and emergency management resources in a conference room, or in transit. You need one system capable of bringing all of them together. Specifically radio, VOIP telephony, cellular telephony, collaboration and conferencing services, and their underlying infrastructure. To do this you need a common denominator – SIP. XOP Networks provides the pieces required to integrate this secure, reliable, universal service. Their services can be deployed in a highly available manner, using data centers, cloud, premises based, or in a hybrid model.

Starting at the edge, XOP provides a ROIP gateway that can be deployed on a processor in your existing routers, or in a separate dedicated unit or units in a diverse, redundant fashion. They also provide the Universal Service Node (USN) which can convert and bridge any protocol into one conferencing system which supports voice, video, chat, screen sharing, document sharing and does so securely and privately on a platform dedicated to your requirements. XOP also provides device independent access to the USN, so users can dial in from a satellite phone, cell phone, VOIP phone, collaboration system, or use any device with a browser to access the conference. Through its robust API, XOP provides a variety of recording, AI, and other interfaces and integrations to comply with recording regulations and all 3rd party applications and partners with the best of breed MSPs and manufacturers should their customers desire one stop shopping. XOP has even developed custom software and designed CPE telephone stations to meet specific customer requirements.  And of course, they provide professional services to manage your project from start to finish and maintain it for the life of the system.

 

Conclusion

As the technology landscape continues to evolve, ROIP will evolve as well. How will technologies such as AI inference and network slicing provide new features and functionality to this market? Will enhanced mobile broadband/massive machine type communications provide large groups of first responders and their support to areas requiring a temporary or even long-term large emergency services presence? Using the airport crash phone example, how does a regional airport scale to support a massive first responder presence if an incident occurs and lasts for extended periods of time? Access is one portion of the solution, but as the access evolves and presents greater numbers of users, you will require a flexible, scalable, proven collaboration system to integrate and efficiently bridge the audio, video, and sharing for any given situation.

No matter what the future may hold, C2 use cases cannot tolerate service interruption as their constituents face potential life or death situations. XOP networks provides these services in a comprehensive solution that ticks the boxes of technology, compliance, procurement, reliability, and performance. They are acutely aware that the acronym CIA (confidentiality, integrity, and availability) is a critical component of any IT policy. Their solutions have been used by users and vendors to provide over 1 million ports of secure services for over 25 years without a millisecond of downtime. These customers and users include service providers, government, financial institutions, the military, first responders and more.

When you select a vendor partner, you choose one based on experience, reliability, performance, and TCO. XOP excels in these areas as is evidenced by their 25-year history in the very demanding C2 and financial sectors. Is your C2 systems integrator an XOP partner? If not, you may want to have them contact us today for a demonstration and discussion of their solutions. As a former XOP customer, I can assure you that after we did, they were deployed in our cloud environment globally. The value was unparalleled, and the decision was easy to make.

Hybrid Ringdown Service: Bridging Private Wire and PSTN Networks

Introduction

As enterprise voice networks continue to evolve, organizations face increasing pressure to support modern collaboration requirements while maintaining reliable connectivity to legacy systems. Financial Trading Floors depend on private wire (PW) services for secure, deterministic voice traffic, while also relying heavily on the public switched telephone network (PSTN) to reach external callers and remote locations.  Issues such as relocation, geography, vendors, technology, and workloads, can create alignment issues that can disrupt trading.

Enterprises vary in their technological evolution paths. Many have moved to UCaaS service platforms and have found out that they are not as flexible as owning your own PBX and integrating in other network providers services.  Additionally, dominant networks providers use their position to limit access to their on net end points.  And to add to the problem, just because one customer decides to change their technology platform, the other end may be unwilling or unable to absorb the cost or deploy the resources required for that change.

Hybrid PW service was created to address this gap. It is a hybrid communication service that combines half private wire and half PSTN into a single solution through protocol interworking. This design allows each end of the circuit to receive the line type best suited to its needs while still functioning as a unified service. Most commonly, Hybrid ARD is deployed using ARD on one side and PSTN on the other to accommodate off-net locations without sacrificing on-net behavior.

 

The Problem

Enterprises with geographically dispersed locations frequently encounter challenges when connecting sites that fall outside of a private network footprint. Extending full private wire services to every location is often cost-prohibitive and slow to implement. As a result, off-net sites must rely on PSTN connectivity, which traditionally treats calls differently from on-net traffic. This separation can lead to inconsistent call routing, higher toll charges, and a fragmented user experience.

Another issue is protocol mismatch. Different locations and systems may require different line types or signaling protocols. Without a hybrid approach, enterprises are forced to deploy multiple parallel services or complex gateways to translate between protocols. This increases architectural complexity, maintenance effort, and the potential for service disruptions.

Integration at the terminating end is also a concern. Calls must reliably reach a B end destination, which may be an enterprise PBX or a modern collaboration service. Managing separate ingress methods for private wire and PSTN connections places additional strain on telecom teams and complicates troubleshooting. Moreover, during outage scenarios, many environments lack predefined mechanisms for quickly rerouting calls.

Finally, business continuity and disaster recovery demand predictable inbound calling behavior. Without specific Direct Inward Dialing (DID) assignments dedicated to Business Continuity Services (BCS) and Disaster Recovery (DR), organizations risk losing inbound accessibility during critical incidents, directly impacting customers, partners, and internal operations.

 

The Solution

XOP Networks presented this solution of Hybrid ARD to resolve these challenges by combining two different line types into a single hybrid service. By using one half private wire and one half PSTN, the service performs protocol conversion between the two ends so that each side receives the line type it requires. This allows enterprises to maintain private wire characteristics where needed while leveraging PSTN reach where it makes the most sense.  Most importantly, the end not making the change is not encumbered by the expense of the distant end’s transformation.

The most typical Hybrid ARD deployment uses ARD on one end and PSTN on the other to support off-net locations. With this architecture, any off-net location can effectively function as on-net. Even though part of the call path traverses the PSTN, the hybrid service presents the call to the enterprise network in a manner consistent with private wire connectivity. This preserves dialing simplicity, cost predictability, and call quality expectations.

Hybrid ARD also simplifies termination options. Calls can be delivered directly to a B end PBX, allowing enterprises to retain existing call control, numbering plans, and user configurations. Alternatively, calls may be routed to a collaboration service, supporting cloud-based communications and remote work strategies. This flexibility enables gradual modernization without disrupting established workflows.

A key feature of Hybrid ARD is the use of specific DIDs for BCS and DR. These DIDs are preassigned and engineered to support rapid rerouting in the event of failures. During normal operations, calls flow to the primary PBX or collaboration platform. During an outage, those same DIDs can be redirected to backup systems or alternate collaboration services, ensuring uninterrupted inbound calling.

Operationally, Hybrid ARD reduces complexity by presenting a unified service model rather than two independent networks. Telecom teams can manage routing, monitoring, and support more efficiently while still benefiting from the strengths of both private wire and PSTN infrastructures.

 

Conclusion

Thought leaders continue to write about the ubiquity and revolution of the brave new world of soft turrets.  However, the reality that they overlook is how the past is integrated into that reformation.  XOP Networks addresses that issue head on with its Universal Services Node and its inherent ability to integrate the legacy, present and future all in one simple solution that can be deployed on pre, in the cloud, or in a data center, and its highly available and redundant.  What’s more, they have been doing it for almost 25 years without any downtime.

Hybrid ARD service provides a practical and resilient solution for enterprises navigating the realities of hybrid voice environments. By combining half private wire and half PSTN, it bridges protocol differences, reduces costs, and extends on-net behavior to off-net locations. Its ability to terminate to a B end PBX or collaboration service ensures compatibility with both legacy and modern systems.

With dedicated DIDs for business continuity and disaster recovery, Hybrid ARD delivers built-in resilience and predictable inbound calling even during disruptive events. For organizations seeking to modernize their voice architecture without abandoning existing investments, Hybrid ARD offers a balanced, flexible, and future-ready approach to enterprise communications.

How MLPP and SRTP/TLS Encryption Elevate XOP Networks’ Platforms

The Problem

In environments where seconds determine outcomes and communication failures can escalate into safety, financial, or operational catastrophes, best‑effort connectivity is not enough. Organizations operating airports, utilities, public safety agencies, industrial facilities, and financial trading floors routinely face congestion, cyber threats, equipment failures, and unplanned emergencies. In these scenarios, communications systems must perform deterministically under stress, ensuring that the right people are connected immediately and securely.

 

The Stakes of Mission‑Critical Communication

In everyday enterprise environments, delayed or dropped calls may be inconvenient. In mission‑critical operations, they can be catastrophic. Emergency responders rely on instant coordination. Airport operations require immediate, clear communication during incidents. Trading floors must maintain uninterrupted, confidential voice communication as markets move in milliseconds. Utilities and industrial operators depend on reliable voice coordination to manage safety‑critical infrastructure.

In these environments, communication platforms must do more than function. They must remain available during congestion, respond instantly to emergency triggers, and protect sensitive information from interception or tampering. XOP Networks’ enhancements address these demands directly.

 

Challenges Without Priority and Encryption

Without call prioritization, critical communications compete equally with routine traffic. During emergencies or peak congestion, high‑priority calls may be blocked or delayed, slowing response times and increasing risk. Traditional quality‑of‑service mechanisms alone are often insufficient because they do not account for application‑level urgency or dynamically changing situations.

Security presents an equally serious challenge. Unencrypted or partially encrypted voice traffic exposes organizations to eavesdropping, call interception, credential theft, and regulatory risk. Voice communications frequently carry sensitive operational details, personally identifiable information, or market‑moving intelligence. Treating voice as less deserving of protection than data introduces unnecessary exposure.

Hybrid legacy and IP environments further complicate this picture. Many mission‑critical organizations rely on analog crash phones, TDM systems, and specialized devices alongside modern SIP‑based endpoints. Modernization efforts often force trade‑offs between reliability, interoperability, and security.

The Solution

XOP Networks has long been trusted to deliver mission‑critical communications across both legacy and IP‑based infrastructures. With the introduction of Multi‑Level Precedence and Preemption (MLPP) and the availability of Secure Real‑Time Transport Protocol (SRTP) with Transport Layer Security (TLS) encryption across its product suite, XOP Networks significantly strengthens its position as a provider of assured, secure, and priority‑driven communications for high‑stakes environments.

The Universal Service Node is XOP Networks’ flagship, all‑in‑one platform supporting audio conferencing, video collaboration, command and control conferencing, hoot and holler, and mass notification services. With MLPP and SRTP/TLS integration, USN becomes a unified platform delivering priority‑driven and secure communications across legacy and IP networks. For enterprise and public sector customers, this means emergency notifications, command‑center conferences, and collaboration sessions are automatically prioritized and protected without deploying separate systems or security overlays.

 

MLPP: Deterministic Priority Under Stress

XOP Networks’ implementation of Multi‑Level Precedence and Preemption ensures that the most critical communications are always completed first. Calls are assigned defined precedence levels based on role, device type, or triggering event. When system or network resources are constrained, high‑priority calls are guaranteed access, and lower‑priority sessions may be preempted if required.

Unlike best‑effort or static QoS approaches, MLPP operates at the session and application level. This allows XOP platforms to adapt dynamically to congestion and emergency conditions, ensuring predictable behavior when it matters most.

 

Event‑Driven Emergency Communications

A key differentiator is the integration of MLPP with event‑driven emergency triggers. Devices such as crash phones, firebars, and alerting systems can automatically initiate prioritized conferences without manual intervention. When a predefined trigger is activated, the system immediately establishes communication, preempting lower‑priority sessions if required. This automation eliminates human delay and ensures that emergency response teams are connected within seconds, even during periods of severe network congestion.

 

SRTP/TLS Encryption Without Compromise

Security in mission‑critical environments must never compromise availability or responsiveness. XOP Networks’ support for SRTP media encryption and TLS signaling protection is designed specifically for real‑time, latency‑sensitive applications.

SRTP ensures that voice media streams are encrypted end‑to‑end, protecting conversations from interception and tampering. TLS secures call signaling, safeguarding caller identity, routing information, and authentication credentials. Together, these protocols provide comprehensive protection for both call setup and the spoken content itself.

Crucially, SRTP/TLS‑based encryption is available across the entire XOP product line. This includes the Universal Service Node (USN), Ringdown Firebar Conference Server (RFCS), Hoot and Holler systems, and XOP’s hosted services. Whether a call originates from an analog crash phone, an IP‑based trader turret, or a remote SIP endpoint, communications remain confidential and secure.

 

Ringdown Firebar Conference Server (RFCS)

RFCS deployments are often found in airports, chemical plants, oil and gas facilities, and military installations—locations where immediate communication during an incident is critical. MLPP ensures that emergency calls initiated by crash phones or alert buttons are always completed, even during heavy network usage.

With SRTP/TLS encryption, these emergency conferences are also protected from interception. Organizations gain secure, deterministic emergency communication while retaining support for analog red phones and hybrid deployments.

 

Hoot and Holler Systems

In financial trading environments, hoot and holler systems support always‑on voice communications that are central to trading workflows. Latency and audio clarity are paramount, and any delay can have financial consequences.

XOP Networks’ encrypted Hoot and Holler platforms demonstrate that strong security does not have to come at the cost of performance. SRTP/TLS encryption protects sensitive trading conversations while maintaining the speed and reliability traders require. MLPP further ensures that critical trading desks or supervisory roles retain voice access during peak activity.

 

Hosted and Managed Services

XOP’s hosted offerings extend MLPP and SRTP/TLS protections to their cloud‑based SaaS  deployments. Organizations benefit from rapid deployment, scalability, and reduced infrastructure overhead while maintaining the same priority and security guarantees found in on‑premises systems.

 

Operational Benefits for Customers

Together, MLPP and SRTP/TLS encryption enable faster incident response, reduced operational risk, and stronger compliance with cybersecurity and regulatory requirements. Communications remain available and secure during emergencies, market volatility, or infrastructure failures. By embedding these capabilities directly into its platforms, XOP Networks avoids the complexity of bolt‑on solutions. Customers gain a unified communications environment that is easier to manage, maintain, and evolve.

 

Conclusion: Raising the Standard for Mission‑Critical Communications

Mission‑critical communication systems are lifelines. They must perform predictably under stress, protect sensitive information, and integrate seamlessly across old and new technologies. With the introduction of MLPP and the availability of SRTP/TLS encryption across its product line, XOP Networks enables organizations to move beyond best‑effort communication models toward assured, secure, and priority‑driven connectivity. These enhancements reinforce XOP Networks’ commitment to delivering future‑ready platforms for the world’s most demanding environments.

Organizations that depend on reliable, secure communications during critical events should look closely at how XOP Networks’ solutions can strengthen their operations.

Modernizing Airport Emergency Communications with Ringdown Firebar Conference Server (RFCS)

The Problem

Airports operate within one of the most regulated, high‑consequence environments in the world. Safety management, operational resilience, regulatory compliance, and coordinated emergency response are central pillars for airport authorities, executives, and operations leaders. Organizations such as Airports Council International (ACI), the American Association of Airport Executives (AAAE), and the Federal Aviation Administration (FAA) consistently emphasize the importance of reliable, redundant, and well‑governed emergency communications systems as a Core Safety Function.

Across FAA Advisory Circulars, ACI guidance, and AAAE training frameworks, effective communication is recognized as a foundational element of airport Safety Management Systems (SMS). During aircraft incidents, runway incursions, fuel spills, security events, or severe weather disruptions, the ability to rapidly notify, assemble, and coordinate response teams is essential.

Traditional crash phone systems have long met this need through simplicity and deterministic behavior. However, as airports modernize infrastructure and expand geographically, these legacy systems often struggle to scale while maintaining compliance, resiliency, and cost efficiency. XOP Networks’ RFCS was architected specifically to bridge this gap without compromising operational integrity.

The Solution

The Ringdown Firebar Conference Server (RFCS) is a centralized emergency communications system designed to automate crash phone and emergency conferencing workflows at airports. With RFCS, lifting a handset or pressing an emergency activation button immediately triggers a predefined call sequence and connects all designated stakeholders into a live, multi‑party conference.

The diagram above shows a typical deployment of the XOP RFCS in an airport environment.

1. The system is redundant and highly available
2. ‘Red Phone’ stations are provided at every critical location
3. Emergency scenarios, conferences, alerting functions, are all preprogrammed
4. Alarms, strobes, doors and light activation, and power control may all be integrated
5. Simple off hook on designated phones activates the system and joins all parties in seconds
6. Always on diagnostics with self-reporting capabilities

This deterministic behaviour aligns with FAA expectations for predictable, repeatable emergency procedures and supports standardised response protocols commonly adopted by ACI and AAAE member airports. A variety of RFCS videos are available at the XOP YouTube channel located at Link.

 

Designed for Airport Authority Governance and Oversight

Airport authorities must demonstrate that safety‑critical systems are not only dependable, but also monitored, auditable, and governed. RFCS includes a secure, web‑based administrative interface that provides authorized personnel with real‑time visibility into system status and emergency activity.

Capabilities include:

1. Live status of all emergency phones and devices
2. Visibility into active emergency conferences
3. Identification of participants and speaking activity
4. Centralized configuration and access control
5. Diagnostic logging to support incident review and regulatory audits

These features support documentation, continuous improvement, and accountability—key components of FAA SMS programs and AAAE‑recommended governance practices.

 

High Availability and Operational Resilience

FAA guidance for airport emergency preparedness places strong emphasis on system redundancy and resilience. RFCS supports high‑availability configurations that allow airports to deploy redundant primary and secondary systems in separate locations.

In the event of a power outage, network disruption, or equipment failure, RFCS automatically fails over with no change to user procedure. Emergency phones and alerting devices continue to operate normally, ensuring uninterrupted communications during precisely the scenarios for which they are intended.

This architecture supports the operational continuity expectations outlined in FAA emergency planning requirements and ACI resilience initiatives.

 

Hybrid Infrastructure Support for Modern Airports

Most airports operate hybrid environments that include both legacy analog infrastructure and modern IP‑based systems. RFCS supports this reality by enabling coexistence of multiple technologies within a single emergency communications framework. Supported environments include:

1. Traditional analog red crash phones
2. IP‑based VoIP and SIP red phones
3. On‑premises PBX and IP‑PBX systems connectivity
4. PSTN and SIP trunk connectivity

This hybrid support allows airport authorities to modernize incrementally while maintaining continuous compliance with FAA operational readiness expectations.

 

Cloud‑Hosted IP‑PBX Integration for Distributed Operations

Airports increasingly rely on remote operations centers, backup towers, and off‑site emergency coordination facilities. RFCS integrates with cloud‑hosted IP‑PBX platforms, extending emergency conferencing beyond the airport perimeter while preserving deterministic crash‑phone workflows. For airport executives and IT leaders, this enables:

1. Elimination or reduction of costly leased lines
2. Inclusion of remote command and control centers
3. Support for contingency and continuity‑of‑operations planning
4. Secure IP connectivity aligned with modern enterprise architectures

 

Scalable for Airports of All Sizes

Aligned with the diversity of ACI and AAAE membership, RFCS scales from small regional airports to large international hubs. Systems can be configured from 8 to 96+ ports and expanded as airport facilities, runways, and terminals evolve.

 

Conclusion: Supporting Safer Airports Through Standards‑Aligned Innovation

XOP Networks’ Ringdown Firebar Conference Server (RFCS), deployed globally in over 100 commercial and military airports, directly supports these objectives by providing a purpose‑built emergency communications platform that aligns with industry best practices, FAA safety expectations, and the operational realities of modern airports.

Airport authorities face increasing expectations from regulators, passengers, and stakeholders to maintain uninterrupted, verifiable, and resilient emergency response capabilities. XOP Networks’ RFCS supports these expectations by aligning proven crash‑phone behavior with modern architectural practices embraced across the aviation industry.

By supporting FAA safety frameworks, ACI resilience goals, and AAAE governance best practices, RFCS provides airports with a forward‑looking emergency communications foundation—one that enhances safety, supports compliance, and strengthens operational confidence when it matters most.

“Sir I cannot hear you” – Air Traffic Management Out of Control?

The Problem

Unless you have been hibernating, you have heard about the recent voice communications outages in our multiple Air Traffic Control centers. You remember voice communications, don’t you? Invented in the 19th century and eulogized many times as shinier objects take center stage, voice  is a critical means of communication especially in the financial industry and in command and control. While E911 and other services evolve to include SMS, video, and other features, connecting to a human being on a reliable system that is clear, simple to use, and recorded for compliance is still the foundation of critical communication.

So then why is century old technology failing so often and putting people lives in danger? Voice is looked down upon by today’s technology elite. It does not attract investment. No one wants to make hardware. Everything has migrated to the cloud. While these may not be negative developments, there are legacy systems that are no longer supported that are aging and may not be easily migrated to the cloud. Voice system manufacturers are abandoning their embedded base every day and summarily ending product lines with little to no warning. Some will argue that we took a very simple technology, analog voice, and made it extremely complex with VOIP and its many considerations. Yes, it reduced the costs for consumer and general business, however for critical communications, it reduced the number of vendors and the market size for those vendors thus driving up the price. Government specifications can be complex, and those requirements may not exist in this APP culture and thus drive higher cost customized solutions where once the same PBX provided overlays for every market segment.

So how do all those issues manifest to create the crisis we have seen unfold over the last few weeks? Some level of government issues a Request for Proposal (RFP) that requires technologies and methods that may no longer be available and have to be created for modern platforms. Government bids can take years to create, garner responses, decide, procure, and implement. Many large governmental contractors and integrators take the approach to bid low and make more money in change orders. This drives up costs and elongates the time for deployment, often by years. Antiquated legacy systems must now survive even longer, may not be properly supported, and have contracted service providers scouring online auction sites for spare parts. Add to that the reduction in qualified staffing for cost savings, and it can culminate in a perfect storm of 90-second service failures to critical voice infrastructure at Air Traffic Control towers.

The Solution

The technology problem is not difficult to solve. However, the implementation is often likened to repairing the engine on an airplane in mid-flight. The legacy system should remain untouched. Its delicate status combined with the need for it to operate in a critical environment means high risk to any well-intentioned interim repair. The new system is not production ready and must be extensively tested so as not to introduce new issues. What can be done is to introduce an interim parallel system that leverages the reliable portions of the old solution and provides an alternative that is always available. Bridging the past, the present and the future is the sweet spot for some vendors. Technologies such as gateways, and protocol conversion can provide that evolutionary step from the legacy world to the new world on an interim basis without migrating the entire solution. By inserting these technologies and integrating them via a standards-based API, business continuity is achieved while disaster recovery efforts are conducted in parallel. Properly handled, it can be transparent to the user.

We must rely on publicly available information and make some assumptions. The first assumption is that the failure was only at the voice system. Secondly, we can assume that radar, geospatial data, and the integration of that data to air traffic control center operational systems – all continued to perform. Third, we can assume that the VHF radio network was up and reliably running. Finally, we can assume that the same radar and geospatial data can be presented to another system. Detection of a failure may also be possible which could trigger an automated switch over to the interim system. Or you can simply put a backup device on each desktop. The best backup is one that is always available and requires no intervention.

By taking that same data and matching it to the aircraft identification and geospatial coordinates, a new system can transfer that call to a specific controller in a specific region. A new conference is then created between the aircraft and the controller. It can be handed off as the location changes to a new center, and integrated chat/IM/SMS/Email or any other alert can be triggered and every event logged as desired. A simple example of this is E911 where your phone number is looked up in a database and an address is matched and overlayed on a map and is instantly presented to the E911 operator, then to police, fire, or emergency service dispatching.
If the controller is connected to the new bridge, and the new bridge is connected to the legacy voice service and the VHF radio via Radio Over Internet Protocol (ROIP) Gateways, then a failure of the old system will never even be noticed. Or both systems can exist in parallel. It can work either way, whichever is the best operational fit for the circumstances.

Conclusion

Although this may seem oversimplified, the concept is sound. The variable is a vendor. When you require a partner with extensive aviation emergency experience, who has had thousands of ports in service spanning multiple years without a single failure you turn to XOP Networks. XOP Networks has been providing RFCS (Ringdown Firebar Conferencing Service) to global airports both civilian and military (including the US DoD) for decades, allowing them to achieve FAA regulatory compliance. Their Universal Services Node (USN) provides Mass Notification to municipalities and schools, provides Command and Control conferencing during rocket launches and provides secure trader voice services to financial institutions on Wall Street. Their REST API allows for the integration of 3rd party software and data for additional features and functionality and enhancements to services outlined above. It can operate in a highly available configuration in the cloud, on servers in a datacenter, or a hybrid configuration. It can integrate with existing directories and identity systems, and integrates with recorders, transcribers, and analytic systems.

So why hasn’t a similar solution been put in place yet? Great question. Anyone who is interested can contact XOP at (972) 590-0200, at sales@xopnetworks.com, or at our website at https://www.xopnetworks.com/. XOP Networks, an American company, located in Dallas Texas, and ready to roll up their sleeves and help solve this problem, and already has an extensive track record of helping to keep passengers safe in an emergency.

Revolutionizing Wall Street Communication: The Power of Hitless Switching in IP-Based Hoot and Holler Applications

Introduction

In the fast-paced world of Wall Street trading, seamless communication is paramount. Traders rely on instant, uninterrupted connections to make split-second decisions that can significantly impact their financial outcomes. Traditional communication systems often fall short, requiring traders to redial and rejoin conferences during technical disruptions. However, with the advent of hitless switching in IP-based Hoot and Holler applications, this challenge is being effectively addressed.

What is Hitless Switching?

Hitless switching is an innovative technology that allows calls to transition between hoot bridges without any noticeable disruption. Unlike traditional methods that require traders to redial to join a new hoot conference, hitless switching ensures continuous communication, maintaining the flow of information without interruption.

The Importance of IP-Based Hoot and Holler Applications

IP-based Hoot and Holler applications are essential tools for traders, providing instant communication channels that are crucial for sharing market updates, trading positions, and strategic decisions. By leveraging IP technology, these applications offer enhanced reliability and audio quality compared to traditional leased line-based systems.

Benefits of Hitless Switching

-Seamless Communication: Traders can continue their conversations without any interruptions, ensuring that critical information is shared in real-time.

-Increased Efficiency: Eliminating the need to redial saves valuable time and reduces the risk of missed opportunities.

-Enhanced Reliability: IP-based systems provide more stable connections, reducing the likelihood of technical issues that can disrupt communication.

Real-World Impact

The implementation of hitless switching has received positive feedback from traders who appreciate the uninterrupted communication and increased efficiency. This technology is transforming the way traders interact, allowing them to focus on their strategies without worrying about technical disruptions.

Conclusion

Hitless switching in IP-based Hoot and Holler applications is revolutionizing communication on Wall Street. By providing seamless transitions between hoot bridges, this technology ensures that traders can maintain continuous, efficient communication, enhancing their ability to make informed decisions in a fast-paced environment.

 

XOP Networks’ Universal Services Node (USN), a state of the art conferencing and collaboration bridge supports IP based Hoot and Holler application with ‘hitless switching’. Typically, the H-n-H conference runs on the Primary USN and simultaneously a proxy H-n-H conference runs on the Secondary USN.

The Automatic Conference Coordinator capability of the USN is always aware of the health of both the Primary and the Secondary USNS. If the Primary USN conference server or the cloud provider network fails, the Automatic Conference Coordinator quickly enables the H-n-H conferences on the secondary conference server located in a different cloud vendor’s network, datacenter, or premise-based server without any intervention. With hitless switching, the traders using the H-n-H conferences are unaware that their conference has moved from Primary USN to the Secondary USN.

Here is a highly technical secret:  If a user must dial back in, or an admin has to restart something, it isn’t automatic failover.

Is there a good reason for your email interface, folders, files, chat/IM, PSTN and collaboration to all be in one environment? If there is, that’s great. But if you only purchased that option because of the old adage about never getting fired if you bought a particular enormous vendor, shouldn’t it work? By integrating a separate multi cloud system, you can decrease your exposure and increase your security. XOP offers secure remote access, LDAP compatibility, and CAPEX and OPEX service options.

 

Conclusion

I was the Chief Engineer of a global telecom company that was about to IPO a few years back. At an event, I asked a customer why they went with us, and not a larger company. The answer was that they were a little fish in the scheme of things, and that our pond was smaller. They could call me or our CEO on our cell phones and know they had the ear of someone who cared about their business and would help them with the problem. I was impressed by that answer and have always remembered the conversation. If I couldn’t say the same about the vendors that I was considering, why would I do business with them? Critical communications such as Financial or Command and Control cannot tolerate 2-hour outages or such a total lack of diversity, redundancy, and proper testing prior to a commercial release. If your communication infrastructure is as critical to your enterprise, then perhaps you should be speaking to your XOP Networks representative about their conferencing, collaboration, mission critical voice, and other integrated services today.

AI and Enhancing Trader and C2 Voice

The Problem

Is Artificial Intelligence just another shiny object, or can it positively impact your business? Every other job posting seems to be for an AI developer. For  certification factories it’s a bonanza. However, AI developers are long on demand and short on supply. The cynical part of me looks forward to when AI can develop itself without human oversight and the certification factories and developers du jour are looking for new opportunities. Six fingered photos and plagiarism arguments aside, are there opportunities to put this to revenue producing or cost saving use? I for one believe there are, and that  it’s never as simple as a LinkedIn video would have you believe. Knowing there is a dearth of development talent, do you buy, build or partner to catch the market window before your competition?

Years ago, a friend selling communications equipment told me a story of his pitch to his customer, a business owner. He told him they could reduce headcount and cost with this new solution. Specifically, operators and secretaries, as the automated attendants, and voice mail, on this new PBX would replace them. It was a family business. The operator was his mother, and the secretaries were his extended family. He lost the sale but learned a lesson. Technology has long promised, but has it delivered those efficient tools that give employees more free time, or more time to do their real jobs? Arguably, it has led to more demands on their time based on assumptions about the efficiency. Reduced staffing has meant more stress among the remaining employees. The current generations have rejected the ‘rat race’ lifestyles of their parents and grandparents. Is it possible to strike a balance and generate that win-win?

The Solution

 I will leave the hierarchical types and numbers of  AI models to other authors. However, the automation of repetitive tasks is a valid and common use case. In its simplest form, AI can help achieve that. We have all interacted with chatbots or auto attendants and have varying opinions on the experience. Like anything, you get what you pay for. If you invest in the development and training of the bot, your customers will have a more valuable experience. When a client has to say ’representative’ ten times to get a live person because your selections, logic, and training failed to resolve your customer’s problem, you have wasted your money possibly at the expense of your customer. Lesson one is to pick the right application, and make sure you properly invest in the project.

Voice assistants are another powerful too, that did not begin as an AI application but are being powerfully enhanced by it. I use one every day, and for me, as it’s on a separate dedicated device that doesn’t take up my real estate on my screen and doesn’t require me to press or open anything, I enjoy using it. It often fails on more complex questions; however, the new AI version will be shortly released that promises to rectify that shortcoming. So, it has replaced my typing in a browser hoping for a good return and scrolling past the sponsored items that I didn’t ask for to get to my answer. It enhances my experience, and I can continue to multitask with two free hands.

How do we add the value of repetitive task replacement with the enhancement of task? By consuming and presenting large volumes and varieties of data so that a user can synthesize it in their daily roles.

Consider a trader with screens full of changing charts, TV audio playing, internal and external hoots and shoutdowns being broadcast, calls coming in and going out to specific traders and firms are being made and logged and you can’t access it. Social media, news and market information are constantly changing, memos and emails are constantly coming in, voice recorders are transcribing events that you had no idea were even taking place let alone having access to. And there they are in the middle of that cacophony as the human information processor responsible for synthesizing everything into a transaction that will make your firm a great deal of money.  Now imagine you are that same trader, and AI was synthesizing all of that for you and presenting it into one easy to consume, visual user experience.

Using that same technology in Command and Control (c2) applications, information may be sent on social media long before the first emergency services call is ever made to  public safety officials, especially where the geography is remote or that hour is late. A report of some natural catastrophic event may begin as a post to a group. Hey, did you feel/hear/see that? By aggregating all of those same feeds and social media, can a disaster preparedness center get a jump on the response to an event in the same way the trader could and thus saves lives?

Conclusion

Systems Integrators, who supply mission critical solutions such as XOP Networks, are building AI into their core applications such as their Universal Service Node that provides financial industry and C2 critical communications systems.  Whether it is for their own customer service application, or for traders and first responders to visualize, synthesize and respond to massive amounts of data, XOP is focusing on enhancement use cases. The technologies mentioned above are available and in commercial use today. None of this is a vaporware or futures discussion. While your specific applications and integrations may require development or SDK/API work, these tools will assist with the dissemination of vast amounts of data to help humans make better, faster, and more informed decisions that can impact financial success and public safety.

Anecdotal Chat GPT use cases may be getting all of the press, but business applications will drive the success of AI and determine whether it is a flash int the pan or has longevity beyond the next shiny object. As with anything, how solutions providers architect and market the value will make the difference. So, learn the lesson of pitching the staff reduction aspect of the business  owners family with automation,  and instead focus on the value of the result. Visualizing and enhancing voice communication has always been a challenge, and XOP Networks is helping enterprises realize the value of the data they have access to and are turning that potential into voice with vision.

ROIP Gateways: The Trusted Airport ‘Crashphone’ System and Its Capabilities Beyond

The Problem

Communicating over a distance has always presented a challenge to humans. From signal mirrors, semaphore flags, and satellites, people have leveraged technology to overcome communications challenges. In my Army days I had radio relay system in my vehicle that took up half the space, so that I could extend the reach of battlefield commanders to their resources. Today, we take speed, availability, and distance for granted with such innovations as cellular telephony, and Starlink. However, in a mission critical environment such as Command and Control (C2), this presents a unique challenge. The communication must be instant, reliable, and able to reach the responders regardless of where they are and what they may be using for communications.  Add to that the need for immediate access to decision makers and experts, and the complications begin to pile up.

How does a dispatcher in an emergency center served via the cloud not only reach their field assets, but the experts and leaders necessary to coordinate a unified response? That dispatcher may be on a console with a Radio over IP (ROIP) interface while the field assets may be on push to talk (PTT) radios, and the experts and leaders who may be travelling and on a cell phone or in conference room located far away in a municipal capital. How does an IT manager securely integrate, provide universal and secure remote access, and archive it for later analysis and compliance? C2 is estimated to be a $45 Billion market with a 6.6 CAGR by 2029. So, solving these problems is not only critical for emergency preparedness, but is a lucrative market for potential vendors.

The Solution

Mass notification services have become standard fare for municipal communications. With one call civic leaders can reach all their residents without sirens or public address systems. These can be further integrated with SMS to send the same message via text messaging, email, or other forms of media. In airports, these systems are used as ‘crash phones’ to bring all the airport emergency services and management together on one system rapidly, securely, and independently of the device they use for communicating. This same concept that has served airport management for years will work in other C2 use cases as well.

Imagine the first responder on the scene on a handheld radio, their supervisor enroute in a vehicle, the dispatcher at a console in a command bunker, and emergency management resources in a conference room, or in transit. You need one system capable of bringing all of them together. Specifically radio, VOIP telephony, cellular telephony, collaboration and conferencing services, and their underlying infrastructure. To do this you need a common denominator – SIP. XOP Networks provides the pieces required to integrate this secure, reliable, universal service. Their services can be deployed in a highly available manner, using data centers, cloud, premises based, or in a hybrid model.

Starting at the edge, XOP provides a ROIP gateway that can be deployed on a processor in your existing routers, or in a separate dedicated unit or units in a diverse, redundant fashion. They also provide the Universal Service Node (USN) which can convert and bridge any protocol into one conferencing system which supports voice, video, chat, screen sharing, document sharing and does so securely and privately on a platform dedicated to your requirements. XOP also provides device independent access to the USN, so users can dial in from a satellite phone, cell phone, VOIP phone, collaboration system, or use any device with a browser to access the conference. Through its robust API, XOP provides a variety of recording, AI, and other interfaces and integrations to comply with recording regulations and all 3rd party applications and partners with the best of breed MSPs and manufacturers should their customers desire one stop shopping. XOP has even developed custom software and designed CPE telephone stations to meet specific customer requirements.  And of course, they provide professional services to manage your project from start to finish and maintain it for the life of the system.

Conclusion

As the technology landscape continues to evolve, ROIP will evolve as well. How will technologies such as AI inference and network slicing provide new features and functionality to this market? Will enhanced mobile broadband/massive machine type communications provide large groups of first responders and their support to areas requiring a temporary or even long-term large emergency services presence? Using the airport crash phone example, how does a regional airport scale to support a massive first responder presence if an incident occurs and lasts for extended periods of time? Access is one portion of the solution, but as the access evolves and presents greater numbers of users, you will require a flexible, scalable, proven collaboration system to integrate and efficiently bridge the audio, video, and sharing for any given situation.

No matter what the future may hold, C2 use cases cannot tolerate service interruption as their constituents face potential life or death situations. XOP networks provides these services in a comprehensive solution that ticks the boxes of technology, compliance, procurement, reliability, and performance. They are acutely aware that the acronym CIA (confidentiality, integrity, and availability) is a critical component of any IT policy. Their solutions have been used by users and vendors to provide over 1 million ports of secure services for over 20 years without a millisecond of downtime. These customers and users include service providers, government, financial institutions, the military, first responders and more.

When you select a vendor partner, you choose one based on experience, reliability, performance, and TCO. XOP excels in these areas as is evidenced by their 25-year history in the very demanding C2 and financial sectors. Is your C2 systems integrator an XOP partner? If not, you may want to have them contact us today for a demonstration and discussion of their solutions. As a former XOP customer, I can assure you that after we did, they were deployed in our cloud environment globally. The value was unparalleled, and the decision was easy to make.

Secure Remote Access to Voice Services

Secure Remote Access

The Problem

Remote work is here to stay for financial and efficiency reasons. Leaders can either continue to bemoan that fact, or they can help their CIO’s craft a strategy that aligns the technology goals with the business goals, making remote work a force multiplier. Now IT leaders must combine this requirement with the trend towards collaboration platforms, and away from on-prem PBX’s or even cloud VOIP solutions. One might be tempted to say that going with a large provider means only the best security. Unfortunately, recent outages and security events do not support that conclusion. Here are a few examples:

-Microsoft and AT&T suffered prolonged outages so far in 2024. The issues were attributed to configuration changes. Wouldn’t you expect a firm that is ‘too big to fail’ to not build in a single point of failure, or to perform proper regression testing, and to have a strategy for immediately and seamlessly backing out and restoring services for such upgrades?

-CrowdStrike. Massachusetts E-911. Enough said?

 

Imagine that you manage first responders in an emergency scenario. You need to connect all your assets at once wherever you are and wherever they may be. Additional resources must securely be able to join as required. Can you press one button and do it securely without fear of failure?

Now imagine you are a remote worker in the financial industry. Your trader voice Hoot and Holler, intercom, shoutdown channels or even ARD and MRD are mission critical. If you are away from your desk and need the information, can you join in time? One such customer was using their PBX conference bridge for a hoot and anytime a user picked up their phone everyone else was treated to music on hold. They needed a dedicated secure system with android, IOS, windows or MAC desktops, and dedicated hardware instruments to accommodate how each trader wanted to use the system. XOP was able to accommodate each trader in the way they wanted to trade, not the way a vendor decides for them.

If your enterprise relied on any of the previously mentioned vendors, you lost the ability to communicate, productivity, and revenue. In the instances of 911, perhaps lives and public safety. The cloud means centralization unless your solution is architected properly, and even then you are betting your business on one vendor, one mistake, and the loss of your entire bundle of apps which are all in the same basket.

The Solution

There are multiple ways to provide secure remote access, and a solution must transparently support both and be device and network independent.

Hosting

Customers require a service that is highly available, diverse, redundant, and secure. A shared service is not for everyone, but whether it is shared or not, you should not be vulnerable. The solution should be available on prem, in a multi-regional cloud, in a datacenter, or in any hybrid combination that you desire.

Security

You have already performed your risk assessments and executed your IT strategy. You manage your own identity and access management (IAM) solutions. IT managers should not have to manage multiple systems, nor inflict your users with additional security inconvenience when you already use LDAP. So, if your user is remote, and they are logged into your network, the single sign on should be all they need to work in your environment because it fully integrates out of the box. You made an investment and plans, and they work. Your vendors should be accommodating you, not the other way around.

Access

We have addressed the hosting and secure parts of the problem. Now let us address access to the mission critical voice applications. There are numerous legacy services still in use globally. Not all firms are on the same evolutionary path. Remote access solutions must accommodate analog, TDM, SIP and WebRTC, and anything that may come next. That means you may need a gateway that can convert from whatever you are using, into that secure conferencing and collaboration system. Your users need remote access on demand and that can mean any PSTN device, a web browser, or any device they have access to at that moment.

Service Management

The system must provide an Administration Portal for you to perform provisioning, moves, adds, changes, and deletes at any time. You need to be able to create new conferences as your needs evolve. It must provide a recording interface or offer its own recording capability. And any data must be encrypted.

Conclusion

XOP Networks provides all these services in one solution that ticks each of these boxes. They are acutely aware that the acronym CIA (confidentiality, integrity, and availability) is a critical component of any security policy. Their solution has been used by vendors to provide over 1 million ports of secure services for over 20 years without a millisecond of downtime. Their customers include service providers, government, financial institutions, the military, first responders and more.

The XOP Networks’ Universal Services Node provides access and gateway from any network to their services. Their conferencing service provides the secure private conferencing you need, and their collaboration service provides the same service full multimedia experience as the big guys, but in a secure, private platform that will make sure that your information remains yours, not public on the dark web.

Dialing in from the PSTN whether cellular or VOIP, and a browser based, secure, private collaboration system can mean the difference between business as usual, or the loss of business, insurance claims, and lawsuits from your customers or against your vendors. I encourage you to contact them and discuss solutions for your specific requirements. Together, you can create a custom architecture that enables your users to leverage technology to achieve your strategic plans. Remember, I was an XOP customer, and I know firsthand the value of their technology solutions.

NEC: How to Properly and Effectively Roll Out a Clear and Official End-of-Life Notice

The Problem

If you have read my previous blogs, you know that I have been highly critical of company’s end of ____ notifications to their customers. The very customers who were loyal, and that paid their bills so the manufacturer could continue to operate. Loyalty should be a two-way street, but often is not. We have all experienced end of _____ for products we rely on. Some merely send an email with a PDF or web link, some are handled well, and others have been borderline dishonest.

I have witnessed firsthand companies that were unable to update their software and hardware because of financial mismanagement. Their choice was to hide this from their customers who believed that their devices were still viable and did not contain risky elements that were no longer supported. They could not produce an update or a replacement because of a lack of funding. They did not want to damage their reputations and let their competitors know their dire straits. They made ‘new’ components from old warehouse stock and bought their own back grey market items from auction websites and sold them as new. Such behavior is reprehensible.

Now let me tell you about my recent experience with NEC, and their exiting the PBX market. It was a Master Class in how to care for your customers, resellers, and partners.

The Solution

Founded in 1899, NEC has a long tradition of professionalism, and high-quality products and services. They are a large international firm with a diverse product portfolio. They have been a market leader in SMB PBX systems for many years. They offered powerful UCaaS and CCaaS services and have always been hailed as innovative. However, even the best of companies such as NEC face decisions on how to invest their capital. Recently they decided to exit the premises-based UC PBX market. But rather than run from this, they leaned into the decision and openly announced this to all customers and partners with sufficient advanced notice.

NEC did not stop there. They reached out to their partners and assisted them with the planning of their transition. We know that almost all firms OEM portions of their offerings. NEC went as far as to put their resellers and customers together with these OEMs and create webinar forums to ensure that the customers and partners had ongoing support, and the same products to offer and support into the future.

How often do you witness that level of loyalty and care for customers? This type of commitment does not just happen. It is a byproduct of an ethically managed business where values have cascaded from top to bottom, internally and externally. There is so much to be cynical about these days, however this duty of care is extraordinary, and I applaud them and their leadership for it, and wish them well in the future.

Conclusion

If you were affected by this announcement, you can join XOP and NEC on a webinar as they work with their customers and partners to transition NEC Meeting Center, and other features beyond the EOL date. Like NEC, XOP values their customers and works with partners who integrate and provide solutions to their customers. Contact your NEC account or product team for the date and time of this webinar, and rest assured that you will be cared for in the same loyal and professional manner that you became accustomed to from NEC. Well done!
