Overview

The Grandstream GBX20 is a colour-screen key module that sits beside a compatible Grandstream desk phone and turns it into a reception or operator console. Its 4.3 inch screen labels 20 keys, each of which can show whether a colleague is busy and transfer a caller to them with one press, so a receptionist or assistant can watch and route calls for many people. Two pages give 40 contacts per module, and up to four modules chain on one phone.

Is it right for you?

  • Suits a receptionist, operator or assistant on a GRP2615, GRP2624, GRP2650 or GRP2670 desk phone, or a GXV3350 or GXV3450 video phone.
  • One module gives 40 contacts over two pages; chain up to four for 160 contacts.
  • It is not supported on other GRP models such as the GRP2614, GRP2616, GRP2634 or GRP2636.
  • For a GXP2140 or GXP2170 phone, the GXP2200 EXT is the matching module instead.

Key features

  • 4.3 inch colour LCD, 480 x 272, so key labels are on screen with no paper labels to update.
  • 20 dual-colour keys per page, two pages, 40 contacts per module.
  • Up to four modules daisy-chained for 160 contacts.
  • Busy lamp field (BLF), shared and bridged line appearance, call park and pickup, speed dial, presence, intercom, transfer and conference on any key.
  • Connects to the phone with a USB cable; firmware is upgraded through the host phone’s network connection.
  • 210 x 124 x 33.5 mm, 360 g per module.

What else you need

  • A compatible host phone: GRP2615, GRP2624, GRP2650, GRP2670, GXV3350 or GXV3450. The module does nothing on its own.
  • One module is powered by the host phone. Only if you chain two or more modules, you also need a 12 V power supply.

Installation

Anyone comfortable setting up a desk phone can fit it. The supplied connector plate, screws and USB cable join the module to the phone; follow the quick installation guide for the order of assembly and use the base stand so the module sits level with the phone. Do not power cycle the module during boot-up or a firmware upgrade. Operating range 0 to 40 °C.

Software and licences

Firmware is upgraded through the host phone, so there is nothing separate to install or license.

Before you buy

  • It needs one of the host phones listed; it is not supported on the GRP2614, GRP2616, GRP2634 or GRP2636.
  • Two or more chained modules need a 12 V power supply.
