Re: [SR-Users] received parameter in route URI not used despite path use_received set to 1

Hi I'd like to make sure I've understood correctly how use_received in path module is supposed to work, because I don't get what I expected to get after reading the documentation I've got a little set up with a UAC behind a NAT registering to a kamailio registrar through a kamailio edge proxy (he UAC is a simple sipp script simulating a UAC behind a NAT) path is enabled on both EP and registrar, and use_received is set to 1 on EP the path, contact and via headers in the REGISTER going from the EP to the registrar are : Via: SIP/2.0/UDP 192.168.26.129;branch=z9hG4bK20da.9f4ab6ad25eae6acdd4bd4d655b320ce.0 Via: SIP/2.0/UDP 10.0.0.5:6060;received=192.168.26.1;rport=23456;branch=z9hG4bK-105-1-1 Contact: <sip:1000@10.0.0.5:6060 <http://sip:1000@10.0.0.5:6060>>;methods="INVITE, ACK, BYE, CANCEL, OPTIONS"  Path: <sip:inside@192.168.26.129 <mailto:sip%3Ainside@192.168.26.129>;lr;received=sip:192.168.26.1:23456 <http://192.168.26.1:23456>> where 192.168.26.129 is obviously the edge proxy then I place a call to the UAC through registrar the EP receiveds the following INVITE : INVITE sip:1000@10.0.0.5:6060 <http://sip:1000@10.0.0.5:6060> SIP/2.0 Record-Route: <sip:192.168.26.142;lr> Via: SIP/2.0/UDP 192.168.26.142;branch=z9hG4bKdf25.142eebc72e940d07ad983a858c67f64e.0 Route: <sip:inside@192.168.26.129 <mailto:sip%3Ainside@192.168.26.129>;lr;received=sip:192.168.26.1:23456 <http://192.168.26.1:23456>> Via: SIP/2.0/UDP 192.168.26.1:34567;received=192.168.26.1;rport=34567;branch=z9hG4bK-107-1-1 From: "1001" <sip:1001@my-fake-domain.com <mailto:sip%3A1001@my-fake-domain.com>>;tag=107-1 To: <sip:1000@my-fake-domain.com <mailto:sip%3A1000@my-fake-domain.com>;user=phone> CSeq: 1 INVITE Call-ID: 1-107(a)192.168.26.1 <mailto:1-107@192.168.26.1> Contact: <sip:1001@192.168.26.1:34567 <http://sip:1001@192.168.26.1:34567>> ... The Route header is exactly what is expected, but the edge proxy still sends the request to the request-URI address (10.0.0.5:6060 <http://10.0.0.5:6060>) instead of sending the request to the received address set in the first Route header The path module documentation states : 3.1. |use_received| (int) If set to 1, the “received” parameter of the first Route URI is evaluated and used as destination-URI if present. kamailio configuration on the EP is almost the default one (just added path support, and modified the REGISTRAR route to forward the request instead on saving the contact, so there is not even a mid registrar on the EP tried with kamailio 5.3.7 and 5.4.4 thanks _______________________________________________ Kamailio (SER) - Users Mailing List sr-users(a)lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users
