The trick is that you need to get your phone to send a message that has a valid domain in the To header field (must match how the registrar is configured), but actually transmit the packet to the public port. It would be much easier if you'd make the public port match the private one. Is there some reason that you've not used the default port numbers everywhere? _______________________________________________ sipx-users mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-users Unsubscribe: http://list.sipfoundry.org/mailman/listinfo/sipx-users sipXecs IP PBX -- http://www.sipfoundry.org/
