I am attempting to do the following:

Someone calls (internal) x8000, get's voicemail(Unity) and the option to transfer to someone else. Option 1 is selected, which transfers to x8001. x8001 is set to forward all calls to an external 800 #.

The problem is, when option 1 is selected, it does forward to the x8001 but then goes to a busy signal.

If I dial x8001, it does transfer correctly to the external 800 #

Any ideas are welcome.
