Hi Ramesh, RFC 3550, Section 8 could help:
If a receiver discovers that two other sources are colliding, it MAY keep the packets from one and discard the packets from the other when this can be detected by different source transport addresses or CNAMEs. Br, Somesh :--) -----Original Message----- From: sip-implementors-boun...@lists.cs.columbia.edu [mailto:sip-implementors-boun...@lists.cs.columbia.edu] On Behalf Of Ramesh Kuppili Sent: Tuesday, May 23, 2017 12:30 AM To: sip-implementors@lists.cs.columbia.edu Subject: [Sip-implementors] Duplicate RTP streams with same source IP address and Port number SIP Gurus, I have a situation where I am receiving multiple RTP stream from the same IP address and port number. But with different SSRC. The media in the both streams is the same (audio, more precisely ringback tone). How should I handle this scenario. 1. Should I accept one stream and ignore the other. If so, which stream should I prefer. 2. Should I mix both the streams and play on the endpoint. I am almost certain that mixing both the audio streams will result in undesirable ringback like tone. Is there a any standard that specifies how I should handle this case. Any pointers in this regard is really appreciated. Thanks in advance. - ramesh _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/mailman/listinfo/sip-implementors _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
