BT launches BT4500 Big Button phone

BT tells us about the features of its recently launched BT4500 Big Button cordless phone with built-in answer machine…

BT has listened to customer feedback and included a number of features on the BT 4500 cordless phone to help making and receiving calls easier, especially for people with vision, hearing, dexterity or mobility impairments. The phone features larger buttons to help prevent mis-dialling, and a backlit screen with a large, easy to read font.

As you would expect, the handset is hearing aid compatible and includes a flashing light and built-in volume boost function. Users can also switch their hearing aid to a ‘T-loop’ or ‘T-Position’ to enjoy a clearer sound. For further details, see BT’s guide to hearing better on the phone [PDF], as recommended by the charity Hearing Link.

Peace of mind

The BT4500’s visual voicemail feature shows users the details of anyone that has called and left a message, whilst the slow playback functionality enables those messages to be played slowly, allowing more time to hear the message clearly. There is also a hands-free facility for any users who might find it difficult or inconvenient to hold the handset while talking, or wish to share the call with others.

Support for BT’s Call Control nuisance call blocking service is a newly added feature across the Big Button range – one which lets users filter and block any unwanted calls. The BT4500 Big Button can block up to 80% of nuisance calls, and has the ability to automatically send international, anonymous (no caller ID), withheld and payphone numbers straight to the answer machine without having the phone ring – a great help in ensuring you receive only the calls you want. [NOTE: Call control feature requires a ‘Caller Display’ service to be supported by your network provider, for which additional charges may apply].

Freedom around the home
BT understands that people enjoy long conversations, and will often need to move around during a call. The BT4500 has an outdoor range of up to 300m and up to 50m indoors (given ideal conditions), and will alert the user if they are about to move out of range. The battery has a talk time of up to 13 hours and standby time of up to 160 hours. There’s also a ‘Live conversation recording’ facility, for those times when you might want  to capture important details and pieces of information such as addresses or directions, and review them later.

According to Dave Barrett, Senior Inclusion and Accessibility Manager at BT, the phone’s array of features, while especially useful for elderly and vulnerable people, can ultimately be of use to everyone. He comments: “We’ve been listening to your feedback, and think this new phone will give added peace of mind. It puts people back in control of their calls.

The BT4500 Big Button cordless phone is available from the BT Shop, priced at £64.99

    looked at one of these today for my partially sighted 80-something mum. two VERY bad features . 1) it doesnt display the whole calling party ID before you answer ,only the last 7 digits and (e.g ‘…nxxxxxx) 2) when you review the missed call log it displays each number in a jerky 3 stage scroll which cannot be slowed down or stepped. quite frankly its not the right tool for the partially sighted and is being returned.

    Is there any way that the scrolling numbers can be stopped on a BT4500 telephone as it is quite confusing.

    I purchase a BT4500 big button phone and so far its been nothing but trouble you cannot have a conversation on both handsets the wife in one room and myself in another as they do not connect, so I will be taking them back for a refund.

    What do I think of the BT 4500 big button phone rubbish two people in separate rooms should be able to have a conversation with the caller but no the damn thing keeps going wrong. So I will be returning the phone for a full refund.

    Bought this and it is being returned for a refund. I cannot see the scrolling display so it is useless. Otherwise fine but this one annoyance makes it impossible to cope with.
