Yealink EXP55 Color Expansion Module

The Yealink EXP55 Color Expansion Module is a powerful productivity accessory designed to extend the capabilities of compatible Yealink T7 and T8 Series IP phones. Ideal for receptionists, executive assistants, operators, customer service teams, and other high-volume call users, the EXP55 provides quick access to contacts, extensions, speed dials, and advanced call handling functions while improving overall workplace efficiency.

Featuring a large 5.5-inch color display with a crisp 480 x 960 resolution, the EXP55 delivers a rich visual experience with color icons and intuitive navigation. The vibrant display makes it easy to monitor line activity, view contacts, and manage call functions, even in busy office environments.

The module includes 26 programmable line keys per page, each equipped with dual-color LED indicators for instant status updates. With three independent page buttons, users can quickly switch between pages and access up to 78 programmable buttons from a single module. Keys can be configured for Busy Lamp Field (BLF), speed dialing, call forwarding, call transfer, call park, call pickup, line appearances, and other commonly used business telephony functions.

For organizations with extensive call management requirements, up to three EXP55 modules can be connected in a daisy-chain configuration, dramatically expanding the number of available programmable keys. This makes the EXP55 an ideal solution for attendant consoles, front desk operations, and enterprise communication environments.

The first EXP55 module receives power directly from the connected Yealink phone, simplifying installation and reducing cable clutter. When deploying two or three modules, an optional 5V/2A power supply is required. Additionally, the remaining USB port on the EXP55 can be used to support extended phone functionality, including USB call recording and other compatible USB accessories.

Designed for seamless integration with Yealink T7 and T8 Series IP phones, the EXP55 combines advanced call management capabilities, flexible programmability, and a premium color display to help businesses streamline communications and improve productivity.
