My place is three years old and has dual telephone sockets in all rooms apart from the kitchen. One hole is for the telephone and the other on the same backplate is a broadband connection and they have filters built in.
The phones are wireless anyway because I don't care about the radiation, what little if any there is.
I always stand well clear of the microwave when opening the door to let the radiation pour out first, I suppose it just drifts away on the floor.

I still have a corded phone just in case of a power cut and I always have my mobile which I can charge in the car if all else fails.
