Hi Răzvan Crainea:

I was sending an U command instead of an L command. This is what I interpreted 
in the documentation. Is working great now. Thanks a lot! This was worrying me 
a lot. I've being dealing with this RTP thing since long. Thought I had to 
implement handling that protocol. Thanks a lot!

Hi, Waldo!

I only see the command for Update (initial request), I don't see the command 
for Lookup(200 OK).
Moreover, are you sure RTP traffic gets to the rtpproxy machine? Because 
RTPProxy statistics doesn't see any packets getting to the server. Can you 
double check if the firewall allows the traffic?

Best regards,

Hi:


I am trying to use rtpproxy with my SIP proxy. It starts a session and both SIP 
clients send data to rtpproxy port as I see on wireshark after I modify the SDP 
part. I see data comming to rtpproxy but no data comes out of it. What could be 
going on wrong? Configuratoin issue? I send here a log of rtpproxy.

Any help is very much welcome.
