DESCRIPTION


The VoSIP service provides a cost-effective, reliable, and secure means of classified voice communications, secret only, for Command and Control (C2) and non-C2 customers with the capability to communicate directly using point-to-point or conference calling. It does provide a media/voice interface (gateway) to the circuit-switched network providing interoperability between the VoSIP service and the Multilevel Secure Voice service.
