[SIPForum-discussion] Getting frame/ethernet header information from a UDP/RTP packet.

[John Downing]

A simple Wireshark capture is the way to go.  I will be running a lab on
this next week as part of my TrainingCity VoIP Hands ON Workshop live
virtual class.  If you or anyone else wants to see how to do it just let me
know and you can join the gotomeeting session for a few minutes when we get
the lab started.
