DEVICE AND SYSTEM FOR SENDING DATAGRAMS IN A REAL TIME STREAMING MEDIA COMMUNICATION SYSTEM

摘要

A call control manager (36) provides for sending datagrams representing real time streaming media frames to a client (18) independent of whether the client is served by a network address proxy (28). The call control manager (36) receives a datagram (252) originated by the client that includes an indicated network address and an indicated port number for receipt of the datagrams representing real time streaming media frames, extracts a source network address and a source port number (254) from the datagram originated by the client, and compares the indicated network address to the source network address (256). The call control manager (36) addresses the datagrams representing real time streaming media frames to the source network address and source port number if the indicated network address and the source network address are not the same (260).
