T73WYealink T73W SIP Phone (No PSU)
The T73W is the wireless twin of the T73U: the same 12 SIP accounts, 2.8-inch backlit colour screen, USB port and EXP55 expansion support, with built-in dual-band 2.4G/5G Wi-Fi 6 and Bluetooth 5.0 added. Buy it for desks without cabling, or wherever staff pair Bluetooth headsets straight to the phone.
The rest of the package is the modern T7x platform: Hall-switch hook for silent hang-ups, Linux 6.1 with TEE hardware encryption, Ultra-HD voice, and headset configuration and firmware updates driven from the phone's own display — including wearing detection for automatic channel switching.
It ships without a power supply. Cabled desks can run on PoE; Wi-Fi-only desks will need the optional PSU, since there is no PoE without a network cable.

Frequently asked questions
Is there a PSU in the box?
No — the No PSU variant ships without one. Use PoE where the phone is cabled; on Wi-Fi-only desks fit the optional Yealink PSU.
Do Bluetooth headsets pair directly?
Yes — Bluetooth 5.0 is built in, so compatible headsets pair straight to the phone without any USB adapter. USB and RJ9 headsets are supported as well.
Is it supported on hosted platforms?
Yes — it is a standard SIP endpoint with auto-provisioning across mainstream hosted PBX services. We can verify your platform before you commit.
Can I still cable it?
Yes — the Ethernet ports and PoE remain, so the Wi-Fi is an option rather than a commitment. Many sites run mixed wired/wireless estates on this one model.
