Pin Sets

I just installed Pin Sets and added all the ext and it is working great.
But to find that when a call comes from external and the ext has followme enabled the ext rings once and the box hangs up the caller saying "Canceled"
As a test I added the full 10 digit phone number to the whitelist and the call goes thru fine. Not really a solution.
This also happens when the call is transferred blind to that ext.
What do I need to do to allow the call from IVR and a blind transfer to dial out the followme number?
