Although many people are led to believe that there is some intrinsic connection between registration and outbound calling by the way phone UIs present these concepts, there is in fact no such connection whatsoever. Registration is an inbound concept, not an outbound concept. You can make calls without being registered. You can make outbound calls using different AAA mechanisms. Being registered in no way implies being able to make outbound calls. They're just completely unrelated. There is a common authentication mechanism used in both scenarios: digest challenge authentication. As a practical matter, Kamailio sends a 407 proxy challenge for requests it is meant to relay (e.g. INVITEs) and a 401 Unauthorized challenge for requests of which it is the logical destination (e.g. REGISTER), and both draw on the same set of authentication credentials and otherwise work the same way. The AUTH route covers both of these cases. -- Alex -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/ _______________________________________________ Kamailio (SER) - Users Mailing List sr-users@lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users
