Next, from the left hand menu, click “Follow me”.
On the far right of the screen, click the extension you just created [in this case, 2001].
On the next page, you'll change the following settings:
Ring Time: 60 seconds [to allow time for the call to connect]
Follow-me List: enter your cel number followed by the pound sign [#]
Confirm Calls: check this so that you'll get a whisper [automated message] saying the call is from the IVR
Terminate Call: hang up [this will be what happens if you don't answer]
