In general, using STUN with sipXecs is neither needed nor helpful, and can cause problems. > These are these settings on this phone. Is it possible some of these to > produce the problems? Not that I can see. I'd suggest setting the DTMF to "RFC 2833", since that's what sipXecs requires. Does the phone log anything when it's rejecting a call? You may have to contact Siemens for help. _______________________________________________ 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/
