TeleMatrix 9400 Series cordless phones have a flat panel design that complements the look of flat screen television sets in the room. Choose from 7 standard or custom color handset accents to match any room décor. Features include patented OneTouch voice mail technology, and an integrated Ethernet pass-through port for guest connectivity. AutoSync pairing automatically registers remote 9400 Series cordless handsets with the base unit when in the cradle. Our optional battery backup feature also helps assure guest connectivity during power outages.
