I am running Wireshark V 1.2.5 on Windows 7 and I have a question on what is the correct method to find all packets in an RTP stream from a trace that has multiple H.323 calls in it. I use "VoIP Calls" and highlight the call I am interested in and click "Prepare Filter". This will give one or maybe a few RTP packets. Originally I thought that the correct method was to use the RTP setup frame :- rtp.setup-frame == 4 However, I was advised by someone that I should use the RTP SSID:- rtp.ssrc == 0xb1854be7 I have a trace where if I filter on the SSID I get 95% RTP packet loss, but if I filter on it via the RTP setup frame, I get 0% RTP packet loss. Which method should I be using? Keith French
