Use Call Protect to prevent unwanted calls

Block fraudulent calls, get spam call alerts, and filter your calls using Call Protect on your AT&T digital phone.

Call Protect features

  • Call validation: Calls that display a [V] on your phone's caller ID show that we’ve confirmed that the call is from the phone registered to that number.
  • Suspected spam call warning: Your AT&T phone's caller ID will display Suspected Spam and a spam type (Political, Nonprofit, Telemarketer, Survey, or Robocaller).
  • Fraud auto-blocking option: Potential fraud calls give the caller a busy signal, and the call won’t go through.

  • Call blocking: If you have a specific number you want to block, press *61 after the unwanted call to block that number. To turn off the individual block, press *80. You can also block and unblock phone numbers under Call Blocking in your phone portal.

  • Call Protect history: Call Protect call history logs your calls for the last 30 days. Calls are categorized by status: flagged or auto-blocked.
