I setup a phantom extension to do external call forwarding (which is working great). Only problem I have is that I can't renumber the phantom extension. So, I have a 2 digit dialing plan. And, currently my office has extensions 10 - 56 as extension numbers, and 57 thru 64 as voicmail ports. When I try to renumber the phantom extension (710) to extension 65 or higher, the system just gives me an error beep, and doesn't seem to let me renumber it to anything.
I don't mind using the 3-digit phantom extension number, but the problem is that if someone dials extension 710 within the auto attendenat, they get the error "You cannot be transferred to extension 71."
Am I over looking something?
