Expansion module with 4.3" color screen

The Yealink EXP43 adds a 4.3 inch 272 by 480 pixel color display and twenty programmable keys with dual-color LEDs to compatible VoIP phones. Three illuminated control keys allow quick page switching for extended key layouts. It is designed for receptionists and power users who need more line appearances or feature buttons than the base phone provides.

Best for high-volume call handling

This module suits staff who monitor many extensions, queues or shared lines and benefit from color-coded status at a glance. Buyers who only need a few extra speed-dials or who use phones outside the supported T4U series should look at simpler add-ons or the phone's built-in keys instead.

Twenty keys per page with color LEDs

Each page presents twenty physical keys, each backed by a dual-color LED that shows line state, presence or feature activation. Three dedicated page-switch keys with their own LEDs let users move between pages without on-screen menus. This key count and visual feedback are the deciding factors for choosing the EXP43 over modules with fewer keys or monochrome indicators.

Questions about this item

Which Yealink phone models accept the EXP43 expansion module?

The EXP43 is built for the Yealink T4U series desk phones and attaches directly to their expansion port.

Does the EXP43 require a separate power supply when connected to a compatible T4U phone?

No, the module draws its power from the host T4U phone through the expansion port, so no extra adapter is needed.

How can I confirm the EXP43 is operating correctly after attaching it to my T4U phone?

The 4.3 inch 272 x 480 colour screen lights up, the 20 keys show dual-colour LEDs and the three page-switch keys illuminate when the module is recognised.
