Product information

The stylish BT 6510 will help you rid yourself of unwanted calls interrupting you at home. With its new Call Control feature you can 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.

It’s stylish design is intended for function, as well as form. Featuring a 1.8-inch full graphic display, it’s clear and easy to read, while improved, larger speakers mean much better quality of sound.

Q & As


BT 6510 Digital Telephone and Answering Machine with Nuisance Call Control, Twin DECT 4.2 5 6 6
Phone Love the new phone and the option to block nuisance callers. 12 February 2014
Excellent product Everything about the phones were what we were looking for. The volume and ringing is easy to hear and we don't appear to get many cold calls now 28 January 2014
Poor sound quality is price of nuisance call feature The main selling point is the nuisance call feature (e.g. if you don't want to be bothered by international calls, you can set the phone not to ring for this type of call. The caller doesn't know this, and it's nice to waste THEIR time for a change!). If it IS a genuine call, they can leave a message - call centres rarely do this. The documentation is misleading (it does not state that BT the call features requires subscription). The downside is poor sound quality. Overall, I'm happy with the purchase because of the nuisance call feature 19 January 2014
BT6510 Digital Phone The main reason for buying this phone was to block nuisance calls and calls where the number is unavailable and withheld. It was very easy to set up and it does work. The number unavailable calls go direct to the answer phone. My rating of average is for the build quality. The phone had a backlit panel to show various information such as a calls list of calls received and dialled. You need this function to do last number redial. But overall I find the phone looks and feels a bit cheap. 09 October 2013
Excellent Purchase! It blocks all those nuisance calls and I have it programmed so that only my VIP list can get through and all others can leave a message. Blocking of nuisance calls is excellent! Peace at last! 13 August 2013
Some problems Sent the first one back because a lead was missing from the primary receiver unit. The next was a complete kit. It gave up after a B.T. landline fault but I eventually got it going again. The sound is quite distorted and it does not display the caller unless you sign up with B.T. ,at extra cost to you the subscriber. Generally disappointing, but it does block unwanted calls which was my main objective. , 05 August 2013
