Hi<br>
<br>
I am getting this dreaded error on a asterisk box when call from one<br>
UA to another using Asterisk as a media relay and openser as a SBC and<br>
proxy.<br>
<br>
chan_sip.c:3779 retrans_pkt: Maximum retries exceeded on transmission<br>
<a href="mailto:1310650592@10.100.0.101" target="_blank">1310650592@10.100.0.101</a><br>
<br>
If I make a call from a UA to the PSTN through Asterisk all is<br>
fine. This only happens when calling from one UA to another on the<br>
same LAN.<br>
<br>
I have posted an example sip trace here <a href="http://pastebin.com/m2262b0ef" target="_blank">http://pastebin.com/m2262b0ef</a><br></blockquote></div><div><br>ACK is not accepted as I could spot quickly, 200ok being retransmitted. Probably there is something wrong with dialog attributes, after Fosdem I can check it better.<br>

<br>
My openser.cfg is here <a href="http://pastebin.com/d5e84aaf7" target="_blank">http://pastebin.com/d5e84aaf7</a><br>
<br>
I realise this is a issue with Asterisk but I have not been able to<br>
find a fix. Therefore I figure there might be something I can do on<br>
openser. The problem seems to be with a ACK not being returned but my<br>
SIP knowledge is not good enough to know how to fix it. Any help is<br>
greatly appreciated.<br>
<br>
Regards<br>
<br>
Jon<br>
