The EXP20 Expansion Module is designed to enhance the flexibility and call-handling capacity of the SIP-T27P and SIP-T29G IP Phones. It features a 160×320 Graphic LCD and provides 20 programmable softkeys each paired with a dual-color LED.
The EXP20 contains a large and user-friendly liquid crystal display (LCD) interface that measures 160×320 pixels, as well as contains 20 physical, dual-color LED keys. The additional screen space and added number of buttons simplifies user navigation and streamlines essential operational functions such as speed dial, BLF, BLA, call forwarding, transfer and hold. Up to six EXP20 phone systems can be strung together on a single daisy chain. The advanced new Yealink EXP20 is an ideal IP phone system for receptionists, administrative assistants or contact center workers who need to monitor and manage a large volume of calls on a regular basis.
