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 five possible states:
      • Ring extensions
        • All checked extensions (2xx) are rung in parallel.
      • 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
        • While ringing, user has the opportunity to:
          • Transfer to a specific phone (2xx)
          • Transfer to a specific user (3xx)
          • Transfer to an outside number (dial specified number given to dial pad)
          • dial someone else in to conference before we all pick up (this is strange, but the button is there!)
          • Send to General voicemail (100)
          • Drop the call
        • 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 normal/priority user routing below)
    • Yes, it is a priority caller, Process priority caller routing (see normal/priority user routing below)

Normal/Priority User Routing

For each user, there is a set of routing steps to be executed serially, depending on if the user is a normal or priority caller, and then based on the current USER mode. A user is a priority caller if they are listed in the priority callers list. Any number of steps can be created, and a dial plan segment should be created for each one.

  • Get house mode
    • If Normal caller, select normal caller steps given house mode
    • If Priority caller, select priority caller steps given house mode
      • Execute next step which is one of four possible states: (TOP)
        • Ring Extensions
          • Parallel ring selected extensions (2xx)
        • Transfer to another user
          • Transfer call to specified (3xx) extension
        • Go to user's voicemail
          • Transfer call to specified user voicemail
        • Transfer to an outside number
      • Loop back around to (TOP)
    • If all instructions are carried out and still unresolved, drop back to menu (101)
