Hi ! Please add some example on wiki related to delay in VOIP communication. Regards, From: cool_capricorn80 () hotmail com To: wireshark-users () wireshark org Date: Mon, 22 Mar 2010 15:30:42 +0000 Subject: Re: [Wireshark-users] How calculate dealy VoIP communication Hi Lars! I am also looking for this information. As I told you in my previous email that I am running wireshark on both end than i guess I can calculate the delay. I am in process of reading RFC3550 but if you give some additional information, reference or example how to do it. That will be very nice. Thanks alot. Regards, Sajid

Unless you have a capture on both ends and synchronised clocks for both captures. You may then compare send and receive times. But there's another way: Actually, most of the time, RTP endpoints do measure the round-trip delay while in conversation and exchange that information via RTCP. So you can watch for RTCP packets in your captures and extract the info from there. See RFC 3550.

How can I estimate the mean delay?
