Watch my review video of this superb digital cordless phone that saved me from having to talk to 3 or 4 nuisance callers every day. It's based on my real world experience of buying and using the phone. I was not given the phone for review purposes and I am entirely independent of both BT and Amazon (two sources of the phone).

I used to get 3 or 4 calls a day from companies, call centres and scammers every day. They were wasting my time and getting me annoyed. However I now know how to block a number and how to stop nuisance calls. All those telemarketing calls and scammers don’t get through any more but everyone I want to speak to do thanks to my new phone.

It is a digital cordless phone with answer machine that is suitable for domestic and home/small office use and plugs into a standard telephone socket. It is claimed to be the first home phone guaranteed to block up to 100% of nuisance calls. The built in Call Guardian technology screens and blocks unwanted calls and acts as a nuisance call blocker. In the two weeks I have been using the phone I have not received a single unwanted call while all my family, friends and customers have all got through.

Basically this is what happens:
  • Your saved contacts get straight through
  • Blocked numbers won't get through
  • Call Guardian handles the rest

Enable Caller Display or Caller ID

One thing you need to know is if you want to get the maximum benefit from your BT Call Guardian you need Caller Display or Caller ID enabled on your line. Depending on your phone service provider and contract the feature maybe free or cost two or three pounds a month.

Having Caller Display allows Call Guardian to recognise your contacts - they get through automatically - while callers on your blocked number list and any caller who withholds their number or has an international number will not trouble you. Callers on your blocked list will hear a message that says, “Calls to this number are being screened by BT all Guardian, the person you are calling is not accepting your call. Please hang up”. All that happens in the background, the phone does not ring and you do not get disturbed.

In normal operation, with Caller Display enabled, any calls from numbers in your contacts, allowed and VIP lists will cause the phone ring normally, just like any ordinary phone. If the caller's number is not in any or your lists Call Guardian asks the caller to announce their name and puts them on hold. The phone rings, you answer and hear the caller's name announced, without having to speak to the caller. You then can choose what happens next.
  • Press 1 to accept the call this one time
  • Press 2 to always accept the call
  • Press 3 to block the call
  • Press 4 to send the call to the answer machine
  • Or press the red button to hang up if you don’t want to take the call at this time

Available Packs

The B8500 Advanced Call Blocker is available as a single handset or multi handset packs to suit your specific needs. The multipacks include the twin, trio, quad and even five handset pack. All the handsets are preregistered so setup will be simple.

If you initially buy a smaller pack and then decide you need further handsets that is no problem, you can add handsets if necessary. Additional handsets cost about £20 and obviously do not come pre-registered, you will have to do this manually but the instruction booklet guides you through the process.

Batteries Included

The BT8500 uses 2x AAA NiMH rechargeable batteries (included). 
Each handset runs on 2 AAA NiMH rechargeable batteries, which are supplied along with the phone. BT suggest the included 750mAh batteries will give up to 21 hours of talk time or 240 hours on standby. I certainly have had no problems with battery power, even after having accidentally left the handset overnight on my desk instead of the charging base. The handset performed without any problems next day (during work hours the handset sits on my desk and not on the charging base).

My previous phone was a BT Hudson 1500 which also used rechargeable AAA batteries but of lower capacity. After three years use the battery performance had degraded to the point where they needed replacing. I found inexpensive Lloytron AAA 900mAh NIMH batteries on Amazon which were of a higher capacity than the originals and gave improved performance. For even higher capacity batteries, but still intended for cordless phones, you could also try Palocell AAA 1100mAh Rechargeable NIMH batteries. No doubt I will be doing the same with the BT8500 once the original batteries need replacing.



Although I’ve only been using the BT 8500 for about two weeks I have found it to be excellent. It does everything it claims to do but with one proviso, you must have Caller Display or Caller ID enabled on your line otherwise you will be screening every incoming call.
With BT Call Guardian engaged you probably won’t even be aware a nuisance call has come in because the phone will deal with blocked numbers, caller withheld numbers and international calls without ringing. Because of the number of nuisance calls I was receiving I began taking a note of incoming numbers using BT's 1471 call feature so when I set up the BT8500 I was able to add all those numbers to the blocked call list. If you do not do the same you will merely have to go through the Call Guardian screening process and add calls to your blocked list as they come in. You can also block a call as soon as it comes in by pressing the onscreen button or even later on by going through your calls list and selecting numbers you wish to block. In my experience the system works really well.  

If you are a bit nervous about whether the BT 8500 will deal with your calls correctly you can leave one of your old phones plugged in. When a call comes in your old phone will ring first, if it cuts off after one or two rings you know Call Guardian has blocked the call. If you check your BT8500 handset display you will see confirmation that a call has been blocked.
As far as price is concerned the BT8500 is well priced considering all the features. When I wrote this the single was about £40, the twin £50, the trio £70 and the quad £90.

If you are suffering from nuisance or scam calls I would recommend getting the BT8500 advanced Call Blocker. It is an elegant looking digital cordless phone that has all the features you are likely to need, it is easy to setup and operate, and has the call blocker technology built in rather than an external plug-in unit.
