How to Block Spam Calls and Robo Calls

Unwanted calls are the bane of everyone and every business that has a phone. Spoofed and illegal robocalls are the most common complaint received by the FCC, and your business has undoubtedly received them (likely even today). If you want to do away with these, here’s how to block spam and robo calls.

Step 1: Register With the Do Not Call Registry

The National Do Not Call Registry is a database of phone numbers that telemarketers aren’t allowed to call legally. The registry is widely used for personal numbers, but business numbers can be added too.

To add your number to the National Do Not Call Registry:

  1. Go to
  2. Click “register your phone”
  3. Click “register here”
  4. Enter the phone number(s)
  5. Enter an email address
  6. Click “submit”
  7. Click “register” to confirm
  8. Click the link emailed to you
  9. Your phone number is registered

Adding your phone number to the Do Not Call Registry won’t prevent illegal scams and solicitations, but it’ll stop legitimate telemarketers from calling your business. There’s still a surprising number of telemarketers.

Step 2: Switch to a VoIP

A voice-over internet protocol (VoIP) phone number operates differently from a traditional phone line. Because VoIPs use the internet rather than a landline or cell connection, users have greater control over the phone number.

Having greater control can help you reduce the number of illegal spam and robo calls. You can set up a phone number so that it’s less likely to be called, and certain controls can be implemented to further reduce the likelihood of calls.

If you aren’t yet using a VoIP phone service, you can add your new number to the National Do Not Call Registry after switching.

Step 3: Set Up an Automated Menu

You can further strengthen your VoIP’s protections by setting up an automated menu. Even if your customers don’t want to navigate a lengthy phone tree, have at least one option to select before reaching a live person.

Most robo calls can’t select from an automated menu. The vast majority of robo calls that still are made to your VoIP will be deflected by a single menu option.
