A member of the Avaya one-X Deskphone Edition family, the 9650 IP Telephone is specifically designed for the "navigator" telephone user. Navigators, such as building receptionists & executive admin staff, manage calls for themselves & for groups of people as a big part of their jobs. The 9650 features built-in button module functionality with one-touch access to bridged appearances, speed dials & feature keys. When used with Avaya Communication Manager 4.0, the 9650 supports up to three SBM 24-button expansion modules.
