Humm... Imay be using an old version of Ethereal, because it does not explicit show RTP or SDP packets.<br><br>I will run tests and post the RTP/SDP capture, thanks a lot for the help!<br><br>Just one thing, yesterday I run nmap to check the ports on both clients and in both of them I saw that ALL UDP PORTS are blocked/filtered by firewall/router/proxy.... do you think this may be the problem? I checked the client source code and I seems to be synmetric.....

HI <br>Use ethereal, or ngrep <br>if not install Download it and install on the Clients side and server side ( for Ethereal) and Ngrep in Server, <br>So that U can see the SDP section in ngrep and in Ethereal u can both rtp packets and SDP messages,
<br><br>I seen the urs Debugs of the OpenSER it doesn't show the properly. <br><br><div><div><span class="e" id="q_111c0255f4743881_1"><span class="gmail_quote">On 4/4/07, <b class="gmail_sendername">Amanda Mattiuz</b>

I have the tcpdump output (from server) and the log from openSER in debug mode here with me... how can I capture SDP specifically? If u teach me I can do it and post it.... in fact I'd love to learn it heheheh
