use ssrc for filter. 
ssrc creation logic is derived from random number generation suggested by rfc.
so it should be different in all calls.

Subject: [SIPForum-discussion] Wireshark Display Filter

I have a large pcap file with about 7 active calls. I can see on one
particular call there is a problem and

need to find out when in the trace the RTP stream ends for this call. I
have identified where it starts

and ports being used, but it seems nearly impossible to find where it ends
as the source/dest addresses

are the same for all calls.


Is there a way to create a Wireshark display filter to show only the RTP
stream with port = 52560 to IP-address1.

This would help greatly in troubleshooting
