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 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:
      • 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
    • If all instructions are carried out and still unresolved, drop back to menu (101)
