Extend your front desk with the Yealink EXP38 expansion module, designed for receptionists, administrative assistants, call center agents, and executives alike. Compatible with the Yealink T26P and Yealink T28P, the EXP38 has 38 fully programmable DSS keys, each marked with a dual-color LED indication light. The EXP38 supports IP-PBX functions you come to expect your VoIP system to handle such as speed dialing, BLF/BLA, intercom, call forwarding/transfer/hold/park/pickup/return, and more.
The Yealink EXP38 connects to the compatible Yealink phone via an RJ-12 cable and can be powered by the phone for up to two (2) EXP38 units. For powering 3-6 units, a power adapter (AC 100~240V input and DC 5V/1.2A output) will be required.

Not quite there
Yealink says you can connect up to 5 of these, but that simply hasn't been true for my company. The 3rd, 4th, and 5th units stop working randomly. Usually the 5th. We've replaced them, followed all yealink's advice, and nothing has helped.
