System and method providing for interoperability of session initiation protocol (SIP) and H.323 for secure realtime transport protocol (SRTP) session establishment

摘要

To provide for interoperability of Session Initiation Protocol (SIP) and H.323 for Secure Realtime Transport Protocol session establishment, a transmit key is received in a first protocol from a first endpoint. The transmit key is mapped from the first protocol to a second protocol and sent in the second protocol to a second endpoint to establish a secure communication session between the first endpoint and the second endpoint.
