Product overview



Standard Due date unavailable

The BT4500 Big Button has large buttons making it not only practical for elderly customers but also an aid to sight, hearing and dexterity impaired customers.

Fed up with sales calls interrupting you at home? The new BT4500 Big Button brings you unique functionality to block nuisance or unwanted calls. Its call management feature puts you back in control, by enabling you to choose the calls you want to take and those you want to block.

Designed in the UK, the BT4500 Big Button offers you a large easy to read display, great sound quality and tons of simple to use features. The BT4500 Big Button's built in answer machine comes with 60 minutes record time - all in an energy efficient package.

Block Nuisance Calls

With the BT4500 Big Button you can choose the type of calls you want to block. For example international and withheld numbers can be blocked, which account for a large proportion of unwanted sales calls. Calls still go through to the answer machine, so if it's someone you want to hear from they can still leave a message. Alternatively if there are specific numbers you want to block, you can block up to 10 numbers from getting through.


Big Button

The BT4500 Big Button is the perfect phone for an elderly customer or sight, hearing or dexterity impaired. The large buttons make dialling easy and accurate and the 1.8” full graphic display ensures clarity when reading the screen.


Hearing Aid Friendly

The BT4500 Big Button is hearing aid compatible, thanks to the built-in inductive coupler. This allows you to clearly and comfortably hear telephone conversations through your hearing aid.


Full of Features that are Simple to Use

Do Not Disturb - For those times when you just want some peace and quiet, switch on Do Not Disturb so that your phone won't ring or light up.

Visual Voicemail - See a list of who's called you, and choose which message to listen to first.

Call Waiting - Shows you who are trying to get through and at the press of a button you can switch to the new call or reject it.

We've also made it easy to divert calls to you to your mobile or other numbers for when you are away from home. Or if you want to have a 3 way call the BT4500 Big Button helps you get it set up in a few simple steps.


All Your Numbers at Your Fingertips

With the BT4500 Big Button you can save up to 100 contacts, letting you keep track of all your favourite people. All these contacts are automatically copied to all of your handsets, ensuring you always have the numbers you need, and saving you time entering them more than once.

5* Bt 4500 Big Button Trio
Reviewed by Colin Titford on 21/08/2014
Having read the reviews on this cordless phone, I decided to give it a try, and it's fantastic. I am partially sighted, so the small print manuel was of no use to me, however, I was able to easily find the manuel online, and was able to magnify the instructions. Once you understand what each button controls, it is relatively easy to set up the phone, and you only have to program one handset, as it transmits your inputs automatically to the other handsets. In less than a week, we have already blocked 3 'cold callers'! Everything about the phone features is just great, and I would definitely recommend this product to others, especially if, like me, they have a sight or hearing disability.
4* Excellent, But.....

An easy phone to set up, but while I was setting up one of the two mains power adaptors failed, had to make do just using one until a new one arrived.
3* BT4500 phone
Reviewed by Anonymous on 03/08/2014
Phone is generally good, except I thought it was supposed to block 'withheld numbers' All it does is send these calls straight to the answer machine. The machine then continually beeps until you listen to the message. Even more annoying, was that it did this with the return call from NHS 111 so I missed the call I really needed! I would not have purchased this phone if I had known this would happen. I thought numbers were totally blocked.

1* This should come with a warning
Reviewed by Anonymous on 18/12/2013
These phones with nuisance call blocker should come with a warning. I bought this phone and it stopped others working, including a corded telephone. Reception was abysmal - noise on the line and very faint even with ADSL plug. Words seemed to cut out. Returning it as faulty. I had to pay for an engineer to come out. I now know the truth and have ordered a set of phones recommended by the independent engineer.
