Reduce VOIP bandwidth usage
If we look deeply at a standard SIP communication structure, there are mainly two part, one is payload/media and another is RTP header and some other info/headers. For a SIP call with G.729 it consumes more than 30 Kbps of bandwidth while the payload size is only 8 Kbps. Rest of the bandwidth is consumed by RTP and other headers. VLC has it's own propreitory VoIP protocol which can replace the RTP and other headers completely and by adding close to 0 Kbps of additional transmission overhead with the payload size. So, VLC can transmit SIP with G.729 protocol without silence suppression with an astounding 8 Kbps only.
