I'm not completely sure what you mean by call flow, but I'll answer with what I think you are asking, please let me know if I'm off base. Also, the bridge connects straight out to the provider without passing through a firewall. Phone dials external number, invite request goes to proxy, proxy and phone authenticate, proxy sends invite to registrar which responds with a redirect pointing to the bridge, proxy sends invite to bridge, bridge responds with a 404 to the proxy, proxy responds to phone with a 404. An odd thing I've noticed that differs between the failed and successful calls is one of the sip via headers on the invite between the proxy and bridge. The rport on failed calls is the same port that the proxy listens on. On successful calls the rport is a random high port number, not sure if that is indicative of the problem or not. * Failed call header: Via: SIP/2.0/TCP 172.22.2.10;branch=z9hG4bK-XX-66c918`Ff7O4WerPX6DHjNI8eg;rpo rt=5060 * Successful call header: Via: SIP/2.0/TCP 172.22.2.10;branch=z9hG4bK-XX-67b4Pdrdq8pBHUFbEnQ0H8w4eQ;rpo rt=32769 _______________________________________________ sipx-users mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-users/
