Don't trust that GW. A CANCEL MUST NOT containg To tag (except if it's a CANCEL for a re-INVITE, but it's not common and it's not your case). > Also, I noticed kamailio sends the INVITE to the second route before > sending the CANCEL to the first one. Was this coded on purpose? (I > believe this doesn't go against the RFC, but it is something curious). It's faster in this way :) Why to wait until the CANCEL is sent? -- Iñaki Baz Castillo <i...@aliax.net> _______________________________________________ Kamailio (OpenSER) - Users mailing list Users@lists.kamailio.org http://lists.kamailio.org/cgi-bin/mailman/listinfo/users http://lists.openser-project.org/cgi-bin/mailman/listinfo/users
