<div class="PlainText">hi!<br>
<br>
try to:<br>
- look in tcpdump of your SIP traffic (use wireshark)<br>
- add logging to your kamailio.cfg<br>
<br>
both points to understand the difference between 2 calls (good and failed).<br>
<br>
The description that you prepared is not informative enough - to understand<br>
what is wrong <br>
(important point: kamailio is sipproxy, and does not operate with such<br>
things as "call")<br>
<br>
try to dig more, prepare more info on the point of view of SIP and share<br>
here.<br>
<br>
cheers<br>
