<div dir="ltr">Hi, <div><br></div><div>After a long break while concentrating on other parts of my system I'll get back to this problem. My system has changed a bit since the last setup, although it's mostly the same: CentOS 6.5, Kamailio on <a href="http://1.1.1.1:5060">1.1.1.1:5060</a> and newly added Asterisk on <a href="http://1.1.1.1:5070">1.1.1.1:5070</a>. I use realtime integration, which seems to work nicely. I'm able to call from a zoiper client to another while signaling goes through Asterisk via dispatcher module functions. </div>
<div><br></div><div>I fixed my kamailio script, there was a copy paste error which caused all my rtp profiles to be rtp/savpf, silly old me for making this mistake! Now my script looks like this: </div><div><br></div><div>

<div><br></div><div>Now I'm getting somewhat similar results as in the beginning of this thread, although, I am having progress as well. I'm not sure if adding Asterisk to the mix (sip.conf has avpf=yes) will make life more difficult but here goes:</div>
<div><br></div><div>I'll try to make a call from a ws client 660 to a zoiper client 771. Call is established, and stays on for 2 seconds, then gets a hang up, which originates from Asterisk, not from either client. What is strange is the sdp descriptions:</div>

<br>
</div>I see that you're trying to talk RTP/SAVPF in all cases. Is this what<br>
you want? Or do you want to bridge between RTP/AVP and /SAVPF? Assuming<br>
that the granstream doesn't support SRTP, you should replace the first<br>
and the last occurrences in this snippet with "RTP/AVP".<br>

<br>
</div>It's not rtpengine which is cutting off the log lines, it's probably the<br>
syslog daemon handling them. On my system I have rsyslogd and it's<br>
handling very long log lines quite nicely.<br>

<br>
</div>I believe ngrep works on a per-packet basis only, which fails as soon as<br>
the UDP packets get fragmented. I have more luck using wireshark as it<br>
reassembles fragments.<br>
