In this article, we’ll cover:

Recommended practices

Adding the Caller ID step is recommended to take control of your incoming calls:

  • If you keep getting calls from certain unwanted numbers, patterns, or private numbers, you can add them to the Caller ID phone list and route them to the Match branch to be hung up immediately, effectively blocking spam or irrelevant calls.
  • If calls come from specific numbers or patterns, you can route them straight to the right department or person so they're handled efficiently.

Caller ID step controls

  1. Phone numbers: Enter the phone numbers or the start of phone numbers you'd like to match, for example:
    1.  '+64' to match all New Zealand phone numbers, or
    2. '+61 4' to match all Australian mobile phone numbers.
    3. To enter multiple numbers at once, include a comma between each number.
  2. Also match private numbers: Allows you to include hidden or unknown numbers and redirect them to a specific path.
  3. Match: This branch sets where the numbers from "Phone numbers" are routed.
  4. No match: This branch redirects any number that doesn't match the patterns or numbers listed under "Phone numbers.”
