Have the latest 3CX phone system v8 and installed lastest Softphone. Have a tunnel setup with a external softphone registered just fine. I am unable to dial out from this softphone to external phone number. what I mean by this is the softphone says its dialing but the phone never rings on the other end. anybody has any idea where i can check to figure out why this happening. Here is a line in the server log: 22:48:30.484 [CM505003]: Provider:[Callcentric] Device info: Device Not Identified: User Agent not matched; Capabilities:[reinvite, replaces, able-no-sdp, recvonly] UserAgent:  PBX contact: I do not know what this mean? Thanks for the help everybody. :?
