Frequently Asked Questions

What is a robocall?

    A robocall is an automated telephone call delivering a recorded message. The term robocall is often used to reference other types of calls made by spammers, spoofers, scammers and more.
  • Spammers can be individuals or organizations that place automated phone calls in a manner that is in willful non-compliance with state and federal laws governing the use of auto-dialers.
  • Spoofers can be individuals or organizations that knowingly transmit misleading or inaccurate Caller ID information. These calls may be placed manually or through an auto-dialer. Spoofers often use various methods to mask their telephone number in order to show a completely different number--often a number that may be local or familiar to you.
  • Scammers can be individuals or organizations that disregard state and federal laws to make calls with the intent of committing identity theft or other types of fraudulent behavior.

Are all robocalls being blocked?

The simple answer is no. Some robocalls are helpful, like appointment confirmations and public notices, while others are meant to cause harm. The harmful robocalls are the ones we strive to block. Spoofers can be especially difficult to block due to the various methods they use to hide their telephone number.

What calls are being blocked?

Our call-blocking solution aims to block as many of the calls made with malicious intent as possible. The calls have the potential to invade your privacy through identity theft, money scams and other forms of fraud.

How are these harmful calls identified?

Our solution relies on data from multiple sources including Carrier Partner Data, SIP Origination and crowd-sourced feedback. All of these sources work together to create a "reputation score" that we use to determine the security risk of that caller and block those that represent a high risk.

What do I do if I think a call is being wrongly blocked?

Simply let us know that you feel a telephone number is being blocked in error. We will no longer block that number when it's owner contacts you.

What do I do if I think my number is being wrongly blocked?

Let us know that you think your number is being wrongly blocked. We can ensure your number will be allowed through our network and will investigate why your number was blocked. While we can ensure your number is allowed through our network, the recipient of your call may have other call blocks in place.

How can I report malicious robocalls?

If you want to report a robocaller, spoofer or scammer, feel free to add your number to the Nationwide Do Not Call Registry at www.donotcall.gov. If you receive an unwanted call after your number has been on the National Registry for 31 days, report it to the FTC here.

What if I don't want any of my incoming calls blocked?

Please let us know if you would like to opt out of this free call-blocking service.

Are there other solutions to identify or block these harmful calls?

Most devices have internal settings that allow users to block unwanted numbers. Some newer wireless devices have options to identify the call as potentially harmful or screen calls for unknown numbers. You can even download various call-blocking apps from your device's app store. We offer free online tutorials for most wireless devices. Once you enter your wireless phone's make and model, check in the Phone or Contact portion of the training to learn how to block a number
