[Asterisk-Users] How to create a secret code to use myasterisk@home server's long distance plan from a public phone

Since my previous response was incorrect, I will go ahead and give the 
instructions.  I pulled these from the forum at 
http://sourceforge.net/projects/asteriskathome/

Instructions for getting DISA to work with AAH (or AMP).

As Adrien pointed out, you should have Digital Receptionist set up or a 
dedicated DID route.

1. Modify your Digital Receptionist menu.  When you get to the screen 
asking for "Number of Options for Menu", add 1 to the value currently 
showing. Click continue
2. The new option should be at the bottom of the list.  Change the Option 
number to a number you would like.  This is the "extension" the caller 
dials to get to the password voice prompt.
3. Click the radio button for Custom App.  In the field, type 
"custom-disa,s,1"  (without quotes).
4. Click Continue at bottom, and then on red banner to apply them.
5. Now click on Maintenance (top of screen)
6. Click on Config Edit
7. Click on extensions_custom.conf
8. Somewhere in the file copy the following:
  [custom-disa]
  exten => s,1,Wait(2)
  exten => s,2,Answer
  exten => s,3,DigitTimeout,5
  exten => s,4,ResponseTimeout,10
  exten => s,5,Wait(2)
  exten => s,6,Authenticate(###) ;any number you want for a password here.
  exten => s,7,DISA,no-password|from-internal
9. Click Update at bottom.
10. Click Re-Read Configs

This set up works for me.
