Block inbound calls to your organization

You have the option to prevent incoming PSTN calls from numbers marked as spam or involved in harassment. The callers are disconnected without hearing any announcement. The calling numbers (coming from the PSTN trunks) are matched against the locally configured E164 patterns that are configured in Control Hub.

For a successful match and call rejection, specify the calling number from the PSTN trunk in an equivalent E164 format.

Blocked contacts won’t be able to call you, but you can still make an outbound call to the blocked numbers.

To create a block list with numbers that can’t make incoming calls to your organization:

1. From Control Hub, go to Services and select Calling.
2. Select Service Settings and scroll to Call Block List.
3. Add or remove phone numbers, country codes, or other patterns to the call block list. Ensure that the numbers and patterns are in E164 format.
4. Enable or disable the following options:
   • Block calls with no caller ID - Blocks incoming calls from PSTN without calling line information (caller ID).
   • Block calls from hidden private numbers - Blocks all calls from callers with private numbers or hidden identities.
5. Select Add.
6. Enter up to 200 numbers or patterns. To add numbers in bulk, select Import CSV.
7. Click Save to save the number.
8. Click Delete to delete an entry or Clear All to delete all numbers in the block list. A notification displays to confirm the action.
