I’m having trouble setting up a DID for an extension. If I configure the DID to go to a DR, it works great, but if I change it to go to an extension, I get my VoIP providers voice-mail system immediately when calling from an outside line. When I look at the server activity, it states that the phone rejected the call. I’m using a Yealink phone that has been provisioned from 3CX. I’m running the free version of 3CX v10.
