Use and tips
The GXP2135 targets desks that take many calls and must see at a glance who is on the line: secretarial desk, reception, switchboard, sales team. Its 32 BLF keys monitor colleagues' extensions and transfer with one press, with no expansion module. Bluetooth lets you use a wireless headset or hand over a call from your mobile phone. On a PoE switch, no power adapter is needed; otherwise, plan the 12 V / 1 A power supply. For a larger 4.3-inch display and 24 physical BLF keys, see the GXP2160.
