A quick start guide

Rated 5 out of 5 by from Peace at last! As a portable 'phone and answering machine the BT8500 functions well and is packed with features, but the clever part is in its call blocking technology. Using the default settings, calls from any number which you have not programmed in to the phone book (including withheld, international, and unavailable numbers) are answered silently and the caller hears a message asking them to identify who is calling and then press the # key on their 'phone. Once they do this the 'phone rings, you hear the recorded voice of the person calling, and you then have various options - e.g. accept the call, block it, direct it to the answering machine, or just hang up. (It is conceivable that a genuine caller might ignore the request to say who they are and hang up but I rather doubt that this would happen if the call was important.) Manned call centres do not bother trying the annouce option, presumably as they know that the call will not be accepted, and automated call systems can't get past the message asking for identification. The privacy settings can be customised so that, for example, you could direct withheld numbers to the answering machine whilst leaving unavailable and international numbers on the 'ánnounce' setting. The only negative points that I have encountered so far (and a small price to pay for the covenience of the other features) are - 1. The time does not update automatically with changes to daylight saving time. 2. There doesn't seem to be any way of displaying the list of blocked numbers. Since buying and installing the BT8500 I have not received any nuisance calls although I can see from the call list that many have been intercepted by the 'phone. My privacy, peace and sanity have been restored at last! Highly recommended.

My current phone (needs replacing) is a BT Verve which allows us links up Our Response door/bell/phone. It fully intergrates with the BT Verve as another phone unit as well as doorbell and talk-to- visiter unit. Will the BT 8500 do the same?

Hi. I have this phone. How do I extend the range so it reaches to a garage?

Asked by: montym
On this occasion Maplin do not stock a product that exactly meets your requirements, or indeed anything close enough to offer you as an alternative.
