The Avaya 1416 supports 16 line appearances/feature keys on the phone itself – and up to 3 x 32-button expansion modules, providing access to a total of 112 line/feature keys or speed dial buttons. This will satisfy the needs of even the most demanding secretary or receptionist. Each of the buttons features a dual LED (red, green) providing explicit status for the user. For a familiar look and feel, the 1416 includes several fixed feature keys for common telephone tasks including conference, transfer, drop, hold, and mute. In addition, the 1416/1616 includes a high quality two-way speakerphone, and supports a broad portfolio of Avaya wired and wireless headsets through its integrated headset jack.
