Professional Overview

The Grandstream GBX20 is a high-performance extension module designed to enhance the productivity and call management capabilities of users in high-volume call environments. It is the ideal solution for receptionists, administrative staff, call center agents, and executives who need to efficiently monitor and dispatch a large number of calls. By transforming a compatible Grandstream IP phone into a powerful attendant console, the GBX20 provides the direct control and at-a-glance visibility required for a modern, fast-paced business.

At the core of the GBX20's design is its large, vibrant 4.3-inch color LCD screen, which provides a clear and intuitive display of contact status and line information. The module features 20 programmable, dual-color keys, and with two switchable pages, it offers a total of 40 programmable functions. For organizations with extensive call handling needs, the GBX20 is highly scalable; up to four modules can be daisy-chained to a single host phone, providing a massive expansion of up to 160 programmable BLF/speed dial contacts. This ensures that even the busiest user has immediate access to their entire team.

The GBX20 supports a rich set of features, including Busy Lamp Field (BLF), speed dial, call park/pickup, call forward, transfer, and intercom. Power is conveniently supplied by the host phone for up to two modules, simplifying installation and reducing desk clutter. Seamlessly integrating with Grandstream's GRP and GXV series of professional IP phones, the GBX20 is an essential accessory for creating a powerful, centralized, and highly efficient call management workstation.
