BT 4500 Big Button Digital Cordless Telephone and Answering Machine with Nuisance Call Control, Trio DECT

Product information

The BT 4500 Big Button Telephone is a practical solution designed to aid sight, hearing and dexterity impaired people. It features large, responsive buttons to make dialling, a large 1.8" full graphic display to make reading the screen easy and has been tested to provide clearer sound. It is also compatible with hearing aids, so you'll be able to comfortably hear calls through your hearing aid.

Key Features:

  • Call Control allows you to choose which calls you answer and which calls are sent straight to the answer machine. For example, you can block all International and Withheld numbers, cutting out a large proportion of unwanted sales calls. You can also block up to 10 specific numbers to stop any particular nuisances from contacting you too.

  • A 'Do not disturb' function prevents your phone from ringing or lighting up in times when you need some peace and quiet.

  • Visual Voicemail will give you a list of who's called you and allow you to choose which voicemail message you want to listen to first, so you can prioritise the most important messages.

  • The large 1.8" full graphic display enables you to instantly view how many voice messages, missed calls or text messages you have, and makes it easy for you to find the number you want from your phonebook. A blue backlight makes it easy to read, even at night.

  • A hands-free speaker mean you can share a conversation with other people in the room or use your hands for something else as you talk.

Please Note: In order to use Call Control, text messaging and visual voicemail features you must be subscribed to a Caller Display Service from your network provider. Charge may apply.

Rated 5 out of 5 by Fantastic phone Had to replace our landline phone due to crackling on line and constant nuisance calls. Read up about this phone bought from John Lewis a few weeks ago. installation and set up easy. Lovely phone to hold, numbers are big and screen showing caller id is clear and readable, volume can be loud if you need, it has everything you need the wife programmed the call blocker we have no nuisance calls if one gets through with a number identified you can block by number have done this must be so frustrating for these callers now they keep trying but call gets rejected . Ha ha 18 March 2015
Rated 5 out of 5 by Very good product. Although there is nothing wrong with my eyesight, the large numbers are very useful. The message display is very clear and messages on the answerphone can be played back slowly. The three sets synchronise and you need only enter your phone numbers once. I am very pleased with the product and can highly recommend. 03 March 2015
