How Does the Phone Number Blacklist Work?

CloudTalk’s Phone Number Blacklist allows you to immediately block undesirable callers, preventing them from wasting your time and money.

When someone tries to contact you using a blocked number, 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.

  What Makes the Phone Number Blacklist Unique?

Immediately Block Undesirable Callers

Block bots, vendors, telemarketers, and spammers in seconds. The Phone Number Blacklist works for both inbound and outbound calls.

Avoid Paying for Spam Calls

Not only does Click to Call save time, but it also supports conversion rate. That results in a higher return on investment. It can increase by as much as 143% on average.

Improve Call Center Security

Many call center cyberattacks consist of hackers racking up your phone bills with expensive international calls for their own good. You can limit your calls only to the countries you need to prevent this from happening. 


Access Accurate Call Center Data

Among other things, spam calls also skew your call center data. By blocking unwanted callers, you ensure you have reliable information to make your most important business decisions.

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.

4. How many phone numbers can I blacklist?

There is no limit on how many numbers you can blacklist in CloudTalk.
