- Wow a clever guy on Dragon's Den has made a device which blocks nuisance callers ringing your phone ... Except that the idea is not entirely new and similar devices in America already existed. And with a smart phone you can set a different ring for different callers in your phonebook and so send calls from people who are not in your phonebook direct to voicemail.
- Ah I see this device is basically a caller ID thing, but you program your friends numbers in. You have to program your phonebook numbers in and a have caller ID service, so when someone calls you the Truecall detects that number and if it is a new number it hangs up or puts it to voicemail. ... what about when someone calls you in an emergency ?? ..the police .. your wife from a phonebox ?
Some of the other devices noticibly £50 instead of £100 just ask the caller to press a number and if they don't it cuts them off hence it cuts off automated callers.
.. simple switchboard phones already have this also your phone company have schemes to block numbers with schemes like "Choose to Refuse" and of course you can do it via program running on your computer for free.
