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.

Q & As

BT 4500 Big Button Digital Cordless Telephone and Answering Machine with Nuisance Call Control, Trio DECT 4.4 5 10 10
Vast improvement Every aspect of this phone is better than its (non-BT) predecessor. Sound is clear and adjustable, big buttons very accessible. Contacts easy to enter and maintain - each handset is automatically updated. Little interference from desktop PC. Only downside is that call blocking does not work as we have another phone plugged into our branch line upstairs. 02 September 2014
A welcome change This phone will be ideal for those with large hands frustrated with handsets getting ever smaller 12 August 2014
BT 4500 Big Button Digital Cordless Telephone and Answering Machine with Nuisance Call Control, Trio DECT Great product! Handsets are convenient size and weight, the numbers are large and easy to see and use, and the audio quality is excellent. The set-up guide is clear and easy to follow, and installation requires only the one telephone socket for the first handset. Reception on all three handsets excellent throughout the property. A very usable and efficient installation for all to use, especially the elderly. 07 July 2014
Easy to use - mostly Positive: Phone and answering machine good, menus easy to master. Have no criticism of the sound quality. Negative: When looking at calls both received and made, the number display is too large and scrolls through too quickly making it difficult to accurately read the number. One handset failed after a couple of weeks. Instant no hassle replacement of complete set by JL (one of our reasons for shopping there!). Hope the replacements are long term reliable. 03 July 2014
Very satisfied This product does just what it says on the box. The big buttons are easy to see and use. The phone blocks nuisence calls - a great plus - and it can be programmed to indicate who has called and the time of the call. We are really pleased with it. 11 May 2014
big clear buttons but poor sound quality when using speakerphone facility I bought this phone for my parents and at first I was very pleased. The buttons are big and clear and the instructions for setting the phone up were very easy to follow. However, one of the main reasons for buying the phone was to have the speakerphone facility but the sound quality when using the speakerphone was very poor and in the end \I returned the phone and received a refund. 06 May 2014
Ok if you're desperate It's ok the buttons are big and clear and it's easy to programme, however sound is not great and it's not very pretty 11 March 2014
