Re: Cannot see RTP packets on end

[Martin Visser <martinvisser99 () gmail com>]

The problem will be that your friends capture probably has not seen the the
related SIP or RTSP control packets associated with the conversation. RTP
runs on top of UDP, but is doesn't use a fixed or well known port, so it is
difficult for Wireshark to always determine whether particular UDP packets
are UDP. If you right-click on a UDP packet that you think is RTP and use
"Decode As..." to select RTP, you should get the result you are after.
