The Yealink EXP55 Color Expansion Module is a high-performance solution designed to significantly enhance the call-handling capabilities of Yealink T7X and T8X series IP phones. It features a large, intuitive 5.5-inch color display (480×960 pixels) that provides a vivid visual experience with customizable wallpapers and clear icons. For administrative professionals and receptionists managing heavy traffic, the module offers three pages of 26 flexible, dual-color LED buttons, allowing for up to 78 programmable features such as BLF/BLA, speed dial, and call transfer. For maximum scalability, users can daisy-chain up to three modules to a single phone, providing access to a total of 234 additional keys.

Engineered for seamless integration, the EXP55 connects directly to the host phone to ensure rapid data refresh rates and reliable transmission. This connection doesn’t sacrifice connectivity; a built-in USB port remains available on the side of the module to support extended functions like call recording via a flash drive. By combining a modern, easy-to-operate interface with massive expansibility, the EXP55 serves as an essential tool for contact center workers and power users who need to monitor contacts and streamline complex workflows with ease.
