Built-in speakerphone with eight-step volume control enables hands-free conversations. A flash button provides access to call waiting, and the redial feature allows you to quickly call the last outgoing number. Handset and speakerphone controls allow you to adjust volume levels to your liking (the speakerphone has eight levels; the handset/headset has four), while a ringer control lets you set the ringer to off, low, or high. A data port is integrated into the base, and dial lock and call restrictions are easily programmable, making this an excellent phone for family or home-office use. A ten-number speed dial allows you to program the most frequently used numbers into the phone and dial them with the touch of a button. Headset jack offers an additional hands-free conversation option. Frequency: N\A; Answering System: N\A; Lines: 1; Telephone Type: Corded.
