Hi there! Just wondering if anybody knows how to resolve the error below? 19:20:31.433 [CM503020]: Normal call termination. Reason: Forbidden 19:20:31.433 [CM503016]: Call(76): Attempt to reach <sip:07967XXXXX@192.168.10.30:5060> failed. Reason: Forbidden 19:20:31.433 [CM503003]: Call(76): Call to sip:07967XXXX@sip.voip-unlimited.net:5060 has failed; Cause: 403 Spoofed From-URI Detected; from IP:18.104.22.168:5060 It occurs when an extension is set to forward to an external number. The call in question is coming in through the same provider as it is being forwarded out of - I'm speaking to the provider but I'm hoping somebody has had the same issue and found a fix! Many Thanks Oli.
