We had to purchase new cordless phones due to the interference we got on old ones from our FIOS service. The Panasonic 4 handset plus answering machine phones were stylish, sleek, and within an affordable range. The whole system sets up quickly and easily, not complicated at all for those who might be tech challenged. The sound is clear on all the sets, I especially like that you don't need a phone jack in all the rooms, only the one at the main base. The features on the phone are handy, there is caller ID, a phone book, an answering machine, and the volume can be controlled at the touch of a button....
