First time posting here, and I could not find an old post about this, maybe didn’t search right. I have a DID that goes to a custom extension that rings the users cell phone. When call come in they go to the cell phone fine but always as “unknown caller”. I have tried populating all of the CID fields with the DID number but Caller ID on the cell always shows unknown caller. Does anybody have any suggestions or a previous thread that I can research? Any help is greatly appreciated, thank you.
