Call Protect features

Incoming Call Verification - AT&T Phone for business Call Protect will verify incoming calls with [V] in front of the number or name. The [V] stands for "Valid Number" and means that AT&T has verified that the call really is originating from the device that is registered to that number, in other words, it is not a call from someone that is trying to pretend it is their number (i.e. a spoofed call). 

This featured is part of a nationwide initiative to reduce the number of unwanted calls.  At first only AT&T and a few other companies are validating calls. As more phone companies come onboard to this initiative and begin validating calls, the percentage of validated calls will increase.

Keep in mind, even if AT&T validates the number, people can still use valid numbers for bad purposes. Always use caution when answering calls from people you don't know.

Calls may arrive without being marked with a [V] due to one of the following reasons:

  • The phone company the caller is using has not yet begun verifying calls. 
  • The call is marked as Fraud Risk or Spam Risk. These calls are not marked with [V]alid Number because it is believed the caller on the other end intends to defraud or is a suspected spammer. 
  • The call has failed validation from the phone company that owns the number.
Calls will be marked [V]alid Numbers when legitimate telemarketers and other callers correctly identify themselves and originate calls from a phone number they own.

Automatic Fraud Blocking1- If the call is “Allowed”, it will ring through as usual. If the call is determined to be potential fraud, the caller will hear a busy signal and the call will not be delivered. This feature can be toggled on or off.

Suspected Spam Call Warning - If the call is determined to be spam, it with be allowed but delivered with “Suspected Spam” as the caller ID name along with a category such as Suspected Spam, Deb Collector, Political, Nonprofit, Telemarketer, Survey, or Robocaller.
