Proposed Asterisk Dialplan

We desperately need to write a new Asterisk dial plan to replace the AMP generated one that has become far too bit-rotten to be of any substantial use. This page will track the conceptual flow of what will be needed for the new post Asterisk 1.8+ dialplan.

Dial Plan Flow

Call from outside line (1xx)

• Call comes in from outside line
  • Get house mode and branch between four possible states:
    • Ring extensions
      • All checked extensions (2xx) are rung.
    • Transfer to a specific user
      • Transfer to specified (3xx) extension
    • Go to a specific user's voicemail
      • Transfer to selected user's voicemail
    • Present a menu to select Home user (101)
      • Is the number listed in Callers for me(?) for a user.
        • Transfer to user extension. (3xx)
      • Present menu audio, and select between options:
      • If explicit extension is selected, ring said extension. (Do we want to allow all extensions to be pressed here?)
      • If User number is selected, Transfer to user (3xx)
      • If General Voicemail, drop to general voicemail box (100)
    • Transfer to outside number
      • Dial outside #

Ring specific extension (2xx)

• Does current house mode allow extension to be rang?
  • No? Bounce to Menu (101)
  • Yes? ...then
    • Ring specified extension
      • If extension does not pick up within specified IVR delay time, Transfer to (101) for IVR menu

Ring specific user (3xx)

• Find user via AGI script, map to a list of (2xx) extensions.
• Is number on Priority caller list?
  • No, it is a normal caller, Process normal caller routing (see per user routing below)
  • Yes, it is a priority caller, Process priority caller routing (see per user routing below)
