Here is the product description in HTML format:
The Yealink EXP40 is a compact expansion module designed to extend the functionality of your Yealink T4xG and T4xS series desk phones. With a dedicated grayscale LCD screen and dual-color LED keys, it gives busy offices and front-desk staff quick access to the extra lines, contacts, and call-handling features they rely on every day.
The EXP40 is built for environments where fast, reliable call handling matters most, such as receptionist desks, call centers, and multi-line offices. Its dual-page layout doubles the number of programmable keys available at a glance, letting users manage more contacts, lines, and features without cluttering the desk with multiple phones. Because it daisy-chains with additional EXP40 units, businesses can scale their key capacity as staffing or call volume grows; just keep in mind that while the host phone can power up to 2 modules on its own, connecting 3 to 6 modules together will require an external 5V/1.2A power supply.
Adding an EXP40 to your Yealink desk phone is a straightforward way to keep your team organized and responsive, without the cost of upgrading to an entirely new phone system. We've been helping businesses find reliable, budget-friendly telecom and IT equipment since 1991, so you can shop with confidence knowing our team has the experience to back it up.
Every item we sell goes through a rigorous 25+ point certification process before it ever reaches your door, giving you added peace of mind that your expansion module is ready to perform from day one. Add this EXP40 to your cart today and give your front desk or busy workstation the extra keys it needs to keep calls moving smoothly.

Expand the capability of your Yealink T4xG or T4xS series desk phone with the Yealink EXP40 LCD Expansion Module. Designed for busy front desks, call centers, and multi-line offices, this module adds dozens of programmable keys so your team can manage calls faster and more efficiently.
The EXP40 is built for organizations that rely on high call volumes and need instant access to extensions, lines, and features.
