Expansion module for Grandstream IP phones

The Grandstream GS-GXP2200EXT is an expansion module designed for compatible Grandstream IP phones. It adds a bank of programmable keys with Busy Lamp Field indicators to a desk phone. The unit provides a 1.26 inch LCD that shows the status of each line or feature. Office workers who handle multiple calls gain one-touch access to extensions, parking orbits and speed-dial entries.

Check phone compatibility and desk space

Verify that the desk phone model supports this expansion module before ordering. The accessory draws power and data from the host phone, so no separate power supply is required. Ensure there is enough surface area for the module’s 4.61 inch width and 1.26 inch screen height. The unit weighs approximately 380 grams and connects via the phone’s dedicated expansion port.

Suits receptionists and multi-line staff.

This module suits receptionists, executives and team members who monitor several lines and need quick call transfer, park, pick-up or intercom functions. It is not a standalone telephone and cannot operate without a supported Grandstream IP phone. Buyers who want a complete phone system or additional handsets should look at separate base units instead.
