I am able to dial a 4 digit transformation pattern that will call a 7 digit number.
I can call the 7 digit number.
I can not transfer the call to the number. So the switchboard cannot transfer callers to this number.
If I set my phone to forward all calls to this four digit number, the number is forwarded without error.
It is only when using the transfer option that it fails from any phone, not just the switchboard.
I also cannot transfer to the number by dialing, 9 + 7 digits.
Using Call Manager 6.1.4.1000-10
