Grandstream GBX20 Extension Module

The Grandstream GBX20 is a powerful extension module designed to expand the functionality, flexibility, and productivity of compatible Grandstream GRP carrier-grade IP phones and GXV IP video phones. As a trusted Grandstream GBX20 supplier in Dubai, UAE, we provide genuine GBX20 extension modules ideal for receptionists, operators, call centers, and high-call-volume business environments.

The GBX20 features a 4.3-inch TFT color LCD display (480 × 272) that provides up to 40 programmable contacts per module, with support for up to 160 contacts when daisy-chaining up to four GBX20 units. This allows users to efficiently manage large numbers of extensions, speed dials, and presence indicators.

Designed for advanced call handling, the GBX20 supports a wide range of features including Busy Lamp Field (BLF), call park/pick-up, speed dial, presence, intercom, and call transfer/forwarding. These features make it an ideal solution for reception desks and operators who need to quickly monitor and route incoming calls.

The GBX20 integrates seamlessly with compatible Grandstream phones, using a local GUI with smooth animations driven by the host device. A single GBX20 can be powered directly by the host phone, while installations with two or more modules use the included 12V power supply. Firmware upgrades are handled easily through the host phone’s network connection, simplifying maintenance and deployment.

With its sleek design, robust build quality, and professional-grade performance, the GBX20 ensures maximum productivity by helping teams efficiently monitor and dispatch incoming calls.
