An 8-line professional IP phone with Bluetooth, Wi-Fi, Gigabit PoE and GBX20 extension-module support for growing desks.
The GRP2624 is the expandable 8-line phone in this batch: where the GRP2634 trades expansion for built-in keys, the GRP2624 keeps a clean front and adds GBX20 support — up to 4 modules for 160 contacts — as the desk grows. It shares the 2.8-inch colour display, 12 SIP accounts, dual Gigabit PoE ports, Bluetooth and swappable faceplates with its sibling, and is managed through GDMS.
