We have recently bought a Phillips set with one main answerphone base and two separate extentions. However, the ringing tone is terribly tinny, even on "Very Loud", and it's difficult to hear in rooms without an extension. The hand sets are lightweight and cheap and nasty, and although I have to admit the convenience of being able to carry them around, the small numbers make dialling difficult if it's a number you haven't pre-prgrammed in. I'm not sure whether our system offers different ring tones for different family members although there is a loudspeaker and intercom facility.
