The Grandstream GXP2200EXT adds 20 dual-color keys and a 128x384 graphic LCD to a GXP2140 or GXP2170, with 2 pages for 40 contacts per unit. It suits secretaries and operators who need to monitor more extensions without swapping their phone.

====

If a GXP2140 or GXP2170 has run out of keys, the Grandstream GXP2200EXT is how you add more without replacing the phone. Each module brings 20 programmable keys with dual-color LEDs and a 128x384 graphic LCD that labels them.

What the Grandstream GXP2200EXT adds

• 20 keys per page and 2 pages per module: 40 contacts per unit.
• Up to 4 modules chained to one phone: 160 contacts.
• Keys handle BLF (standard or eventlist), call park and pick-up, speed dial, intercom, conference and transfer.

No power adapter needed

The connector plate screws the module to the phone, and the RJ11 cable in the box goes to the phone's EXT port. Power and firmware both come from the phone. Keys are set in the phone's web interface under Advanced Settings, MPK EXT Settings.

Typical Saudi setups

A secretary's desk at a Dammam company tracking every manager's line, or a mall switchboard routing calls to shops, security and maintenance.

GXP2200EXT or GBX20?

Both give 20 keys over 2 pages and chain up to 4 units, but they are not interchangeable. The GXP2200EXT fits the GXP2140 and GXP2170, with a 128x384 graphic LCD, an RJ11 cable and host power. The GBX20 fits GRP2600 and GXV3350/GXV3450 phones, with a 4.3-inch color screen and USB cable, and needs a 12 V supply once two or more are connected.
