Thanks, I have download wireshark and for rtp it use rtpdump. What is
the best format for dump rtp with rtpdump ?
In the help of rtpdump I have the choice between
format : hex|ascii|rtcp|short|payload|dump|header
Usage: ./rtpdump [-F [hex|ascii|rtcp|short|payload|dump|header] [-t
minutes] [-o outputfile] [-f inputfile] [-x bytes] [multicast]/port > file
Tonight I will try the dump format of rtpdump tool
