Filter Function

Filter unique phone numbers

With a filter in your dial plan, you determine what happens to an incoming call based on the phone number. For example, you can route all German phone numbers to a colleague who speaks fluent German, or you can block certain numbers by disconnecting the call. You can create a filter for a specific number, a group of numbers, or a portion of a number (for example, +33 or +49 if you want to filter callers from France or Germany).
