i have trouble with BYE routing and loose routing and kamailio
sometimes looping itselft Bye packets.i checked loose routing and
bye packet routing here
<a class="moz-txt-link-rfc2396E" href="https://voipmagazine.wordpress.com/2014/12/05/strict-and-loose-routing-of-sip-sequential-requests/">"https://voipmagazine.wordpress.com/2014/12/05/strict-and-loose-routing-of-sip-sequential-requests/"</a>
and here <a class="moz-txt-link-freetext" href="http://www.ietf.org/rfc/rfc3261.txt">http://www.ietf.org/rfc/rfc3261.txt</a> .<br>
<br>
i tought that if top route header with lr is itself , next route
header will be sent but it sending itself so looping. once , it
was happened on INVITE transaction and i disabled register_myself
on domain module. , couldnt figure out why it happens.<br>
<br>
Kamailio2 and Asterisk has same interface but different port. i
put and exit method when looping itself and saved day.<br>
<br>
<br>
