T77UYealink T77U SIP Phone with a 7-inch Touch Screen
The T77U is the touch-screen flagship of Yealink's T7x range, aimed at executives and anyone who wants smartphone-style navigation on the desk. The large 7-inch touch screen makes switching between pages, directories and applications quick and obvious — no soft-key gymnastics.
Its party trick is the dual USB ports: they support Bluetooth, Wi-Fi, USB headsets and USB call recording via the appropriate accessories, and you can run any two at once. That keeps the base price down compared with radios-built-in models like the T74W, while letting you add exactly the wireless you need.
If a touch screen is more than the desk needs, the T74U covers the same platform with a conventional display — and if you want a bigger Android-based touch experience, look at the T87W.

Frequently asked questions
Does it include a power supply?
A PSU is not bundled for PoE-focused rollouts — power it from a PoE switch port, or add the optional Yealink PSU if you have no PoE available.
Is Wi-Fi built in?
No — Wi-Fi and Bluetooth are added via Yealink USB dongles in the two USB ports. If you want the radios built in, choose the T74W or T87W instead.
Can I record calls on the phone?
Yes — plug a USB stick into one of the USB ports and the T77U supports local USB call recording.
Will it work with my hosted PBX?
Yes — it is a standards-based SIP phone with auto-provisioning support across mainstream hosted platforms. We can confirm your provider before you order.
