Sorry, I forgot to post the SDP message from the client that originates the
INVITE. Here it goes:
Content-Type: application/sdp
v=0
o=sip:amanda@195.176.182.183 0 0 IN IP4 84.72.112.122
c=IN IP4 127.0.0.1 <http://195.176.182.183/>
t=0 0
m=audio 2100 RTP/AVP 0
a=PCMU/8000
I notice from here that the audio ports described here and in the server SDP
message are different. Could this be an issue??

From the server I got:

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.
