BT 6510 Digital Telephone and Answering Machine with Nuisance Call Control, Twin DECT

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.

A Do Not Disturb function will allow you some peace and quiet, ensuring the phone won’t ring or light up to disturb you, while certain contacts can be marked as VIPs- enabling them to get to you even in your peaceful moments.

Great phones Easy to use, with large buttons these phones are ideal for all ages. Good clear answer phone with long message time. Great Value for money. 04 August 2014
Excellent product I am so pleased with these phones. They do all I could wish for-VIP TONES, DO NOT DISTURB MODE-block unwanted calls etc. Have used Phillips in the past but these do all they did and are much cheaper so great all around. Would highly recommend. 23 July 2014
Good overall product Easy to set up and use. Only one negative you have to be quick in putting in mobile numbers before it reverts back a screen 16 July 2014
Great phones Good quality easy to use and good value for money,these phones have various choices of ringtones and are nice and loud if needed to be. Very happy with the purchase. 25 June 2014
Good value for a good product Easy to set up, literally out of the box and plug it in. Good sound quality, though I had to play around with the volume settings so the ring tone wasn't ear-splitting. Solid, attractive and robust looks and all the necessary functions. Limited ring tones, but that's not a problem for me. I can access voicemail from the 2nd handset too. All round, a very good buy. 27 April 2014
No more unwanted calls Brilliant. It was easy to set up, very easy to block all those unwanted calls, occasionally one gets through by using a 'proper number' but just enter that number into the blocked list. Also no longer have to get up to answer it, keep it near by and return to cradle at night. I recommend it when ever nuisance calls are mentioned. 22 April 2014
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
