Panasonic KX-TG6644B DECT 6.0 Cordless Phone with Answering System, Black, 4 Handsets

Panasonic's KX-TG6644B DECT 6.0 Plus Expandable Digital Cordless Telephone has an answering system and 4 handsets. The DECT 6.0 Plus technology means increasing the frequency of error correction up to 80x, improving the transmission quality and range. A powerful battery back-up system keeps you connected when the power goes out so you can make and receive calls with the cordless handset. The Intelligent Eco Mode automatically lowers the power consumption when you are using the handset close to the base unit. The Range Boost technology extends transmission range by up to 20% so you can keep talking as you keep walking. Other features include Tone Equalizer to control bass, mid-range or treble tones in a caller's voice and Talking Caller ID and Call Block (with required subscriptions).
