HI
Use ethereal,  or ngrep
if not install Download it and install on the Clients side and server side (
for Ethereal) and Ngrep in Server,
So that U can see the SDP section in ngrep and in Ethereal u can both rtp
packets and SDP messages,

I seen the urs Debugs of the OpenSER it doesn't show the properly.
