This multihandset cordless landline telephone employs Bluetooth technology to also let you place and receive cell phone calls. After pairing your Bluetooth-enabled cell phone with the system, you can switch back and forth between cell phone calls and landline calls easily with a press of a button. The telephone's DECT 1.9 GHz technology provides clear reception with minimal interference because it avoids the crowded 2.4 and 5.8 GHz frequencies. Each handset has a speakerphone that provides loud and clear voice quality. The digital answering machine saves up to 14 minutes of messages that can be accessed from any handset. The system supports up to 12 handsets (additional handsets sold below). Two handsets are included; a full charge of each handset provides up to seven hours of talk time; each handset includes its own recharging base. Plugs into AC. Base Unit. 6 3/4" H x 5 1/4" W x 4" D.
