The aircraft is on the ground, and the parking brake is on

screw "send to voice mail". I want the phone to *PICK UP*, play one of a selection of pre-recorded messages, and then allow the caller to press a button if they really really want to interrupt, or answer the question in the message. 200MHz on an ARM is plenty of power to implement this.
