Because it determines the proper route based on the method described in the 'mhomed' section of the docs.
Your choices are either to let Kamailio do that, or set mhomed=0 and choose the egress interface manually based on your own criteria. You can do this by setting $fs prior to t_relay(), e.g. $fs = 'udp:x.x.x.x:5060'; Bear in mind that this combination of transport, listener and port must correspond exactly to one of the listeners. It sounds like that's what you need to do. -- Alex -- Sent via mobile, please forgive typos and brevity. _______________________________________________ Kamailio (SER) - Users Mailing List sr-users@lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users
