Must Be Connected to a Panasonic PBX, June 17, 2008
This review is from: Panasonic KX-T7720 24 Button Advanced Hybrid Speakerphone/telephone (Office Product)
This phone was not designed to be connected directly to an outside phone line. Instead it should be connected to a Panasonic digital or hybrid PBX system. It features a speaker-phone, automatic redialing, call conferencing and excellent sound quality. It can be used on a desk or mounted on a wall. Twelve buttons with lights can be custom programmed, so they connect to outside lines or to other extensions and indicate whether such connections are busy. A standard 4-wire (2 pair) CAT3 connection between this phone and the PBX is all that is necessary to enable all of its features.
