number of digits in the AA & Voicemail extensions must be the same as all the other tabs

Auto Attendant Script: Choose aa_transfer.aef
Menu Prompt: Choose AAWelcome.wav (or you can record your own prompt and
upload)
Enter Options for each digit to route to an extension etc.

These can be changed to meet the requirements of the VAR / customer network.
