I seem to recall that one or two folks in here have got the BT8500 cordless phones that have TruCall technology built in and can block unwanted calls.
I know that it can be set up to answer a call, ask the caller to say their name, then it rings your phone and says something like "It's Fred's Double Glazing Company" at which point you zap the caller or whatever. My question is, what happens if you have a corded phone plugged in as an extension? Presumably it would ring immediately upon receipt of the incoming call whereas the 8500 will remain silent while it does its bit, but do they work alright 'together'?
We told my in-laws that they should have a corded phone in the bedroom in case of power cuts but they're now to infirm to mess about plugging/unplugging as and when needed and the corded phone needs to stay plugged in. Unfortunately though, they're getting quite a few junk calls, hence the need for something like the 8500.
