How To Block All Nuisance Calls – BT Halo Nuisance Call Blocker

At some point in your life you’ll have received a ‘nuisance call’, whether it be someone asking you to partake in a survey, someone claiming you’ve won a large sum of money, someone selling you a product or even dead silence.

There are a reported 8 billion spam phone calls made every year with the Information Commissioners Office receiving around 175,000 complaints in 2014. The calls are extremely frustrating, especially when you hear stories of elderly relatives signing up for things over the phone.

First of all, we’d advise all customers who are receiving nuisance calls to register their number with the Telephone Preference Service. This the central opt out register where you can enter your details and choose not to receive unsolicited sales and marketing calls. Theoretically, all companies should not contact ANY numbers on this list without your consent to do so.

Unfortunately, some of the unethical companies will continue to call you despite you opting out of the TPS. This leads us to the only other option, BTs range of Advanced Call Blockers:

BT Halo Nuisance Call Blocker

BT Halo Single
BT Halo Single –

The latest phone from BT will block up to 100% of nuisance calls. The phone features a technology called Call Guardian powered by trueCall, which works by screening all calls before your phone even rings.

You have the power to block all incoming calls and only allow phone numbers in your address book. If this seems a bit extreme you can decide for yourself whose calls come through by choosing one of the following settings within your BT Halo:

  • Announce – All calls not in your ‘Contacts’, ‘Allow’ or VIP list must say their name. Those on your ‘Blocked’ list hear, “Calls to this number are being screened by BT Call Guardian, the person you are calling is not accepting your call. Please hang up”.
  • International – All calls from International numbers must announce their name. All other calls, except those on your blocked list hear the message above and all other calls come straight through.
  • Ans Phone – All calls not in your ‘Contacts’, ‘Allowed’ or ‘VIP’ list are sent straight to the Answer Phone including those in your Blocked list.
  • Custom – You choose how you’d like to handle all of your calls.

In Announce mode (default setting), the BT Halo will filter all first time calls from numbers that are not yet saved in your ‘Contacts’, or already on tour allowed list. By doing this, you gradually build up these lists and your phone will know how to deal with the call the next time it comes in. 

These different settings give you the ability to block up to 100% of nuisance calls.

The Block Button

The block button is the most powerful button on the phone and will become your best friend.

When you have an incoming call, the handset will show ‘Announced call’. When you pick up the handset you’ll hear the caller announcement so you can decide whether to take the call. If you don’t want to take the call, simply press the ‘Block’ button. The caller will then be advised that their call is not accepted and the call will be disconnected.

The number will then be blocked and added to the blocked calls list. If that number calls again they will hear, “Calls to this number are being screened by BT Call Guardian, the person you are calling not accepting your call. Please hand up.”

You can also do this if you’re already in a call or answered it by accident. Pushing the ‘Block’ button will add the number to your blocked numbers list and they won’t be able to contact you again.

If you already have a list of blocked numbers you can easily add them manually to your new BT Halo, the same way you would add a list of contacts.

  1. I would like a answer to the following question please:-
    On my BT8600 is it possible to view the list of blocked numbers and remove one accidentally added? if not, is this a facility you can introduce retrospectively? I obviously do not want to unblock all the numbers I have had to block up to now.

    Thanks, Martin Chapman

    1. Hi Martin, it’s definitely possible to do this. In settings you can view a list of blocked phone numbers and delete from there. Thanks

      1. I can’t find a way to do this, but I can’t believe it’s not possible as that would render the allow and block list virtually useless. I have only found two options so far for these lists, one to add a number and the other to delete all numbers. Where exactly is the option to edit the list?

  2. Some of my withheld numbers are my hospital or doctor (withheld for good reason security) can I block withheld numbers after I’ve answered them if they are cold calls. I’m using bt8600 phone

      1. I tried withholding my mobile number today during a test call, but I don’t think I had an option to block the caller (only options 1 & 4 presented if I recall correctly) which would make sense because how can you allow or block a witheld, i.e., an unknown number? Can you explain please? Thanks.

  3. We’ve got a BT8600, our Call Guardian settings are set announce but all our calls, regardless of whether they are in our contacts, have to announce their name. What are we doing wrong?

    1. It sounds like your settings are on their strictest setting. Please refer to the manual within the box and change the settings.

  4. Keith,
    I have an BT 8600, I am well pleased it has stopped All unwanted calls dead in there tracks. Best thing since sliced bread.

  5. Is it possible to use a conventional cordless phone in conjunction with a bt8600? I already have a very good traditional phone so am obviously reluctant to buy more bt8600’s than I need and would put the old phone in an area where it would have only occasional use.

  6. Hi All
    Are the BT 4600-Trio and BT Décor 2600-Single in any way compatible ? I want to use them in four separate rooms but only have one telephone line.
    I already have the Caller Display Facility
    Thanking you all in advance :- Philip Taylor
