Re: How calculate dealy VoIP communication

You can't get it directly.
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.

        Hi,
        
        I know how to calculate the bandwidth, jitter and loss packets of RTP traffic. How can I estimate the mean 
delay?
        
        Thank
