Hey All, I always struggle with loose_route() and I implemented workarounds in the past. But, I want to get a better understanding.
I have a SIP Endpoint -> Kamailio -> FreeSWITCH The domain and alias is set to the ip address of the Kamailio server (137.184.130.206) When I get the ACK back from the SIP Endpoint it looks like this ACK sip:[email protected]:5060;transport=udp SIP/2.0 Via: SIP/2.0/UDP 10.1.10.140:1052 ;branch=z9hG4bK-524287-1---740db0025fa217ce;rport Max-Forwards: 70 *Route: <sip:137.184.130.206;lr>* Contact: <sip:[email protected]:53790;transport=UDP> To: <sip:[email protected]>;tag=5gv4etZ8tUUcH From: <sip:[email protected];transport=UDP>;tag=0af5b751 Call-ID: fWido7VIUKIEI6f6kf4vkQ.. CSeq: 1 ACK User-Agent: Z 5.5.8 v2.10.17.2 Content-Length: 0 Kamailio will then remove the ACK and change the RURI to itself, which causes an ACK loop. This is what is look like *ACK sip:137.184.130.206;lr* SIP/2.0 Via: SIP/2.0/UDP 137.184.130.206;branch=z9hG4bK3fd.0cf34b683f0627ee2455594ea6cb2517.0 Via: SIP/2.0/UDP 10.1.10.140:1052 ;received=50.192.97.226;branch=z9hG4bK-524287-1---740db0025fa217ce;rport=1052 Max-Forwards: 69 Contact: <sip:[email protected]:1052;transport=UDP> To: <sip:[email protected]>;tag=5gv4etZ8tUUcH From: <sip:[email protected];transport=UDP>;tag=0af5b751 Call-ID: fWido7VIUKIEI6f6kf4vkQ.. CSeq: 1 ACK User-Agent: Z 5.5.8 v2.10.17.2 Content-Length: 0 *Question:* What am I missing here? We have the alias set and we even set it in the domain module (with the register_myself flag). We have workarounds for this, but I would prefer to figure out how to have Kamailio handle this natively via the loose_route or tm module. Thanks in advance,
