Abstract
A communications system and associated method distributes media in a communications network. A Session Initiation Protocol (SIP) communication session call is established between a caller and a communications server. A message is transmitted from the communications server to the media server that includes Session Description Protocol (SDP) parameters for media provided by the media server. Media is delivered to the caller in a packet format in accordance with the Real Time Transport Protocol (RTP) to reuse the same socket as the source IP and port numbers and update RTP timestamps and sequence numbers. The media is transferred to the caller with minimal jitter buffer flushes and network resource usage.
