Hi, If your "almost the default one" config is like https://github.com/kamailio/kamailio/blob/master/etc/kamailio.cfg[1], i guess it's the removal of route header at line 437/538. # - remove preloaded route headers remove_hf("Route");
loose_route() is only done in WITHINDLG, which checks for has_totag() You should look at https://kamailio.org/docs/modules/devel/modules/rr.html#rr.f.loose_route_preloaded[2] Regards, Kristian.

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[11]) 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 [email protected][12] https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users[13] -- Daniel-Constantin Mierla -- www.asipto.com[14] www.twitter.com/miconda[15] -- www.linkedin.com/in/miconda[16] Funding: https://www.paypal.me/dcmierla[17] -------- [1] https://github.com/kamailio/kamailio/blob/master/etc/kamailio.cfg [2] https://kamailio.org/docs/modules/devel/modules/rr.html#rr.f.loose_route_preloaded [3] mailto:[email protected] [4] http://sip:[email protected]:6060 [5] mailto:sip%[email protected] [6] http://192.168.26.1:23456 [7] mailto:sip%[email protected] [8] mailto:sip%[email protected] [9] mailto:[email protected] [10] http://sip:[email protected]:34567 [11] http://10.0.0.5:6060 [12] mailto:[email protected] [13] https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users [14] http://www.asipto.com [15] http://www.twitter.com/miconda [16] http://www.linkedin.com/in/miconda [17] https://www.paypal.me/dcmierla
