Your T7X or T8X handles the calls. The EXP55 gives you the keys to work them fast. 26 physical keys per page, dual-colour LEDs, and a 5.5" 480 × 960 colour display with backlight so you can read names in a dim office at 6pm. Three pages of programmable keys — 78 total. Daisy-chain up to three modules for 234 keys if your reception desk is running a full queue. USB 2.0 port on the module for headsets, Wi-Fi dongles, or call recording. Wallpapers and screensavers included, so it doesn't look like a hospital monitor
