How-to Redirect Calls According Their Area Code

Problem

You need to filter calls coming from specific area codes (when they pass the filter they can be redirected to different IVRs/extensions/voicemail boxes or simply terminated) – this could be used to limit which regions can call your toll free number, or redirect users to different language queues depending on where they call from.

Step-by-Step Guide

Before you begin: be sure that your Condition True and Condition False destinations are created (if one of them ends up in a terminated call you need only to create the other).

  1. Login to ClusterPBX under your Client account
  2. Click the Inbound Calls Rules entry in the menu
  3. Click the Add button in the toolbar

  4. Fill in the Add/Edit form with the following information
    • Name: name that will identify the rule
    • Match caller ID number (regexp): ^1?(514|438|450)[0-9]+$

      The regular expression above will accept all calls starting with the number 1 followed by one of the following area codes 514, 438 or 450 and any quantity of numbers.

      You can add as many area codes between the parenthesis as needed.

    • Destination if condition is true: choose a destination & target
    • Caller ID prefix if condition true: text that will be displayed before user’s caller ID
    • Destination if condition is false: choose a destination & target
    • Caller ID prefix if condition false: text that will be displayed before user’s caller ID
  5. Click Apply
  6. Go to the source (DID, extension, queue, etc.) and set the new Inbound Call Rule as its destination.
