Hello everyone, New to 3cx, but not new to IP PBX systems. Have been deploying Yeastar asterisk style boxes for the past year with little to no problems. The company I work for has decided to make the move to 3cx for it's VIP clients. I love 3cx and how it seems to function right out of the box, however, I'm getting an odd error when trying to make outbound calls. Explanation of network: Broadsoft Switch in the Cloud > FIOS > Edgewater Router (which is acting as a registration SBC ) > 3CX server Version: 12.5 Steps to reproduce the issue. At 3cx Phone (windows client) dial external number and press call. Receive error: Call Failed. Destination Not Found. Checked the Server activity logs. Code: 12-Jan-2015 17:49:33.420 Leg L:9.1[Extn] is terminated: Cause: BYE from PBX 12-Jan-2015 17:49:33.370 [CM503020]: Call(C:9): Normal call termination. Call originator: Extn:102.

Does that mean on the broadsoft switch or is that specifically on the 3CX server? From what my googling of this error means, it's something to do with the remote party ID? I do know for this Broadsoft switch, for outbound calls, the "From User" needs to be the same as the user name for the trunk. I didn't see a place for me to set that anywhere. Any suggestions?
