The idea is that a client has two open connections and two registrations from the same device. The registrations has the same UUID in the contact, but different reg-id's. When an edge proxy returns 430 when the registrar uses one reg-id contact, the registrar needs to retry with the other reg-id. So there are two issues here: Kamailio acting as an edge proxy that receives registrations and adds a path header, and answers with an error code if the connection to the client is lost. The other is Kamailio as a location server that understands that it has two registrations from the same device and only use one of them, with the others as failover. /O _______________________________________________ sr-dev mailing list [email protected] http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-dev
