Yealink • SKU EXP40
A legacy backlit LCD expansion module with twenty physical keys across two pages, providing up to forty programmable functions for selected Yealink T4 phones.

The EXP40 adds BLF, speed dial, transfer, park, pickup and other supported functions to selected Yealink T46 and T48 phones. Up to six modules can be daisy-chained, but the EXP40 is a legacy/end-of-sale product and exact phone, firmware and power rules must be checked.
Quick answer: Choose EXP40 only for a confirmed compatible T46S, T46G, T48S or T48G installation. It does not support current Yealink phones generally, and external power may be required as module count increases.
Use two pages of twenty keys for supported contacts, lines and call actions.
Daisy-chain multiple modules where the host phone, firmware and power design permit.
Identify the supported T46/T48 host models before ordering a replacement module.
A quick fit check for Australian businesses comparing equipment for users, rooms, sites or wider projects.
