This is correct. According to RFC 5626, when the REGISTER includes a Contact with +sip.instance and reg-id params the registrar MUST NOT check the call-id and cseq of the request, but just the +sip.instance and reg-id params (and the registering AoR in the To header of course). -- Iñaki Baz Castillo <i...@aliax.net> _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
