Call block lists

A call block list blocks calls to and from unwanted numbers across your entire account. When a call matches an entry in the list, Live Hub disconnects the call immediately.

Numbers can be added to the block list in two ways: - Your phone number provider can identify numbers as spam or otherwise suspicious. Live Hub can automatically add those numbers to the block list. - You can manually add phone numbers or number prefixes when you identify unwanted calling patterns.

Live Hub blocks calls before they consume resources or incur charges: - Blocked calls do not count toward your calls per second (CPS) limit. - You are not billed for blocked calls. - Blocked calls do not appear in dashboard metrics, which helps prevent spam traffic from skewing your reports. - Blocked calls remain available in routing history for 30 days, allowing you to review what Live Hub blocked.

## Add a number or prefix

A call block list entry can block a specific phone number or an entire number prefix. You can configure the entry to match the called number, the calling number, or both.

To add an entry:

  1. In the Navigation pane, select Routing, and then select the Call Block List tab.

    The Call Block List tab

  2. Click Add Prefix.

    Adding a prefix

  3. In the 'Prefix' field, enter a full number or a prefix. A prefix can end in *.

  4. From the 'Type' drop-down list, select which number the entry matches on: Called number, Calling number, or Called and Calling numbers.

  5. Click Create.

    Live Hub checks the entry and rejects duplicates. Once accepted, the entry takes effect immediately.
