I am fairly new to the Asterisk Gateway Interface. Couple of questions.
My end goal is to have a script that automatically page when a call is parked. In esscence, the operator would park the call and then presented with a selection (eg. 1 for management, 2 for IT, 3 for marketing, etc...) and once the entry is set an automated page would go out and say something "Management pick up on 71. Management 71."
