If you want full control over what calls you want to pick up, and those you want to block, nothing does it better than the BT4600 Big Button twin handset. This device has an Advanced Call Blocker feature that’s supported by TrueCall’s aware winning technology. The BT ‘Hot Key’ also helps with this by providing you with the option to block calls with just one touch. Not only can you block 100% of nuisance calls but you can also block up to 1000 calls, what more could you want. With the Call Guardian feature, it asks the caller to say their name and then asks the user whether they want to accept or block the call without speaking to the caller. The answering machine can record up to 60 minutes of messages and what is more, it’ll even give you a slow playback of them, so you won’t miss a thing. The phones are delivered with the UK line cord. For Ireland, please buy an adapter 7180641.
