The Yealink T73U is an all-in-one business desk phone that pairs a 2.8-inch backlit color screen with Yealink’s ultra-HD audio and a Hall-switch handset for a quieter desk.
It registers up to 12 SIP accounts, does 5-way conferencing, and drives up to 40 programmable keys across 5 pages, expandable to 234 keys with up to three cascaded EXP55 modules.
The T73U is the wired sibling of the T73W: dual Gigabit PoE ports and a USB 2.0 port cover USB headsets, call recording, and expansion modules, and it skips the built-in Wi-Fi and Bluetooth for desks that are already cabled. Security-wise it adds TEE hardware encryption and a dual-system backup on top of TLS 1.3, SRTP, and 802.1X, and it deploys with true zero-touch provisioning via Yealink RPS.
