Have questions?

1. What is the Phone Number Blacklist?

The blacklist is a list of phone numbers you do not want to receive calls from. To block a call, add a phone number to the list. You won’t be able to call contacts added to the blacklist and vice versa. You can add numbers to the blacklist via the contacts on your phone or manually.

2. How do I blacklist phone numbers?

First, log in to your CloudTalk account. From the left-hand menu, navigate to “Account”, choose “Settings”, and then click on “Blacklist”. From there, you can edit your blacklist by clicking “Change” and “+Add Phone Number”.

Select the Area Code of the number you want to black in the newly opened tab and enter the Phone Number in its basic form. Choose whether you want to block the number for Inbound, Outbound, or both types of calls, and click “Save”.

3. What happens when I blacklist a phone number?

When a blocked number tries to contact you, they’ll hear a message saying that your phone number has been disconnected, and the call will be immediately terminated to stop them from leaving any voicemail.
