Expansion Modules
Get expansion modules at IP Phone Warehouse. Expansion module, attendant console, sidecar — whatever you call it, add keys to compatible phones. Give power-users additional feature keys, speed-dial keys, or quick action keys. They are designed to fit with the style of the base phone, and might feature color LEDs to indicate status or self-labeling LCD screens for simpler updating through your phone system. Many modules can be powered through the base phone using PoE (Power over Ethernet), while others require a separate power supply. Find expansion modules from the leading brands — Poly (Polycom), Cisco, Yealink, Grandstream and many more.
