Hello! I tried to search information about my problem at the internet and local sites/forums, but I didn't find solution. My provider need in CONTACT field: "7455@providerserver.com" (7455 - is login on provider server), but FS send: gw+gwname@mydomain.com<gw%2Bgwname@mydomain.com> ". If I use option "<param name="extension-in-contact" value="true"/>" in my gateway config - FS send this: "7455@mydomain.com". As a result, my external calls didn't send over this provider: "2010-03-20 17:56:30.852222 [NOTICE] switch_channel.c:669 New Channel sofia/external/7451 [0ab674ec-bc8c-48e0-9235- eb395dfe02b0] 2010-03-20 17:56:30.915402 [NOTICE] sofia.c:4788 Hangup sofia/external/7451 [CS_CONSUME_MEDIA] [NO_ROUTE_DESTINATION] 2010-03-20 17:56:30.918438 [NOTICE] switch_core_session.c:1179 Session 28 (sofia/external/7451) Ended 2010-03-20 17:56:30.918438 [NOTICE] switch_core_session.c:1181 Close Channel sofia/external/7451 [CS_DESTROY] 2010-03-20 17:56:30.919604 [INFO] mod_dptools.c:2353 Originate Failed.
