Usually inbound routing does not differ if the call comes from a local subscriber or from an external domain. Outbound routing is performed if the domain in the request URI (ruri) is non-local. regards Klaus Am 29.06.2012 19:46, schrieb Auro Tripathy: Hi All:   I’m a newbie, excuse the simple (no pun intended) question.   I installed Kamailio and I’m able to set it up so that all subscribers in the *same* domain can talk/discover-presence, etc.   What do I  do so that subscribers in other domains, for example the iptel.org domain, can talk to subscribers in my domain?   -Auro     _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users(a)lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
