There are several situations where audio conferencing becomes ‘mission critical’. For example, during a Satellite launch, multiple people from around the globe get involved in monitoring the progress of a mission. One or more mission directors may need to communicate with their multiple team heads, other mission directors, personel from satellite manufacturers, personnel from satellite launch service provider, the end customer and other stake holders instantaneously. Such communication is typically provided by using Hoot and Holler networks that are built using traditional leased lines terminating into a conference bridge. Each site is equipped with CPE that allows personnel to join different ‘conference nets’ by pressing mechanical ‘push’ buttons. XOP Networks’ IP based Hoot-n-holler application changes all that. With XOP approach remote locations can be equipped with TDM to IP media gateways or with IP phones directly. All of these devices from around the world then home into XOP Networks’ USN running the IP based Hoot-n-Holler Conferencing application. The Mission Directors are provided with web portals that can be accessed over the Internet for monitoring multiple individual H-n-H conferences. Via these portals individual Mission Directors can either simply ‘monitor’ or can have ‘talk and listen’ access to any of the conference nets with a simple mouse click. The use of VoIP minimizes the cost of mission critical conferencing, and the use of web portals for conference net selection makes the application accessible to larger number of people and free from any mechanical failures – a constant headache with the legacy approach.
