All about Call Protect for Digital Voice

Your Digital Voice service comes with Call Protect at no extra cost, meaning you’re automatically protected. Call Protect enhances the call experience by detecting and blocking spam and fraud calls, without blocking your important calls.

Our partner, Hiya, delivers an AI-powered service which monitors incoming calls in real-time and notifies you of any suspected nuisance calls. This means handsets with digital screens will display a nuisance call warning for possible spam calls, or the name of the genuine business if they’re registered with our partner Hiya.

Scam calls will be automatically diverted to junk voicemail, so you’ll never be bothered by the call.

As a Digital Voice customer, you can access and manage Call Protect in three ways:

  1. Using a handset supplied with the Digital Voice service - indicated on handsets by an HD logo
  2. By logging into My BT
  3. By dialling 1572 from any phone connected to the Call Protect service.

You may still receive suspicious calls that are not displayed as Call Protect. This is because an unwanted call for one person might be a wanted call for someone else. To constantly improve accuracy, Call Protect uses a self-learning engine that continuously enhances its capability to assess each call.

If you have seen no reduction in suspicious calls, it’s likely the service has not been activated on your line yet.  

Contacting Hiya 

If you have received a call which you think has been incorrectly displayed, you can report these directly to our service provider Hiya at Submit a request – Hiya (

If you are a business you can register directly with our service provider, Hiya, to ensure your businesses name appears.

Staying Safe

Call Protect is very successful when protecting you on most occasions, but it’s not 100% guaranteed. BT cannot accept liability for scam calls.

Handsets compatible with Call Protect

If you are a Landline customers can upgrade to Digital Voice for free to benefit from our new, AI-enhanced Call Protect, however they may still use the previous version on their existing landline until they upgrade.

If you don’t have a phone with a digital display, you’ll still be protected from nuisance calls. However, you’ll not see what number or business is calling or warning messages such as “Nuisance ?”.

Using Call Protect with your handset 

If you already have a handset with a digital screen your with your Call Protect service, we identify and add a list of nuisance callers who we'll send straight to you junk voicemail, cutting down your unwanted calls. This is the BT Blocklist and is turned on automatically with your new service. 

Your own Personal Blocklist is also turned on automatically with your new service and allows you to send numbers to your junk voicemail. It puts you back in control of your calls: you can block certain call types, like Withheld, International or Unrecognised numbers, sending them straight to your Personal Blocklist.

You can also listen to your junk voicemails from the main menu.
