A 12-line professional IP phone with 24 multipurpose extension keys with a paper slot, a 4.3-inch colour display and Wi-Fi 6.
The GRP2636 suits offices that want a paper-labelled key bank rather than a screen-based one: its 24 multipurpose extension keys come with a paper slot, so names can be printed and swapped without reprogramming a display. Behind that sit 12 lines, 16 SIP accounts, a 4.3-inch colour display, dual Gigabit ports with integrated PoE and Wi-Fi 6 on hardware version 5.0 and above, with headset support and GDMS management. Note that it does not support an extension module — the 24 paper-slot keys are the extension capacity of this phone. Call AccessStore.lk for a quote — island-wide delivery.
