The BT8600 comes with BT's unique Virtual Assistant, which means you'll never have to speak to another cold caller again*

  • Virtual Assistant screens incoming calls
  • Numbers on your contact list get straight through
  • Numbers you have blocked are rejected
  • For all other calls, the Virtual Assistant asks the caller to say their name and then asks the user whether they want to accept or block the call without speaking to the caller

Even more advanced call blocking*

  • One touch call blocking - simply press the one touch button if you don't want to take the call and send the number to the blocked list

5* BT8600 Telephone
Reviewed by R S Stacey on 26/10/2017
The phone was delivered very quickly. It all worked very easily from the start and I am very pleased with it so far. The telephone feels comfortable in use and the speech through the speaker is clear and no distortion.

Excellent phone. Download pdf. It gives more information. If you need help and don't want to wait for your call to be answered, use the email address supplied. Their response was excellent. Don't connect the phone line until all handset batteries have been charge for at least 24 hours. To my surprise, I discovered that nearly all my nuisance calls came from international numbers, presumably to avoid being fined by Ofcom. Since I don't expect any calls from foreign countries, I have blocked them. I haven't had a nuisance call since.
5* Excellent . If you're fed up with rubbish calls, buy this now!!!

Excellent device.
We have been plagued with nuisance calls for years and were delighted to discover the 8600
It is easy to programme and has stopped all the unwanted calls. Ii even blocked one wihile I was still in the process of setting it up!
We have been recommending it friends for the past 3 weeks and cannot speak highly enough of it
5* Excellent product

Bought a twin for the kitchen and study with a basic Duet210 in the hall for use in a power cut! It has killed nusiance calls stone dead. You do need CLI on your phone line for it to work and contact numbers must be in full including the STD code. I found the user manual adequate and easy to follow. Also the setting up of contact numbers, settings, etc was very intuitive.

Dr JJ Rigby is wrong in his review. Page 35 of the user guide says how to call another handset. And you don't need to 'transfer calls', just pickup the second handset and put down the first!

Absolutely brilliant piece of kit.
Call Guardian really effective.......
Everyone should have one......the nuisance callers will be soon be out of business.!
8600 model great value for money at circa £60.for three handsets and an answering machine.
User guide is as "user friendly" as I have found anywhere......
but initial setup of the essential Contact list needs care.....and a good read of the manual....

Brilliant, it does everything it should do. Main problem, many of my friends complain about the "Announce message". It starts in a garbled way with a female voice and the insertion of my name has long pauses, my male voice and then switches back to the female voice so that some friends gave up at this stage and did not complete. The use of the word "Announce" is enough to put anyone off. Why not just start with "Calls to John Whoever are being screened ... (followed by the rest of the original words and allow the gender of the whole to be male or female to fit in with person who has the Call Blocker phone?
5* Poor advice from BT Help
Reviewed by T. Tallis on 10/05/2016
As I was getting plagued by nuisance calls I was advised by BT to get the BT8600. It arrived quickly and the install instructions were followed. It blocked all the phone numbers I programmed I put into the phone it should not have blocked. After 3 days of endless calls to the help line and re-installing caller display it still blocked all call that were in the call book. I decided to return the phone as it seemed faulty. A replacement phone arrived after a few days and surprise, surprise the same fault. BT checked the phone line and said there was no faults. I decided to contact the software company as BT were no help! The answer was change the BT ADSL splitter/filter it is likely to be causing the problem! Change the filter and the phone works as it should and passes the installed phone numbers as it should without blocking them. No thanks to BT!

Been waiting for a phone system like this for years. Purchased from B.T. recently , set it up and added all our contacts , and "BINGO" havnt received a single nuisance call since. I got a couple of friends not in our call list to try calling us to see what happened to them, they were prompted by the system to leave their name and hold , the phone then rang at our end , we were informed who was calling and given the option to allow once or always, which I subsequently did, and then added to the list of callers. Absolutely delighted with this purchase. Have already been onto friends that we know are equally annoyed by the volume of nuisance calls, I suspect the number of companies using this particularly irritating practise will plummet rapidly. Many Many thanks B.T.
