Description
The Yealink SIP-T77U is the touch screen model in Yealink's T7 series, with a 7-inch 800x480 color touch screen, 16 SIP accounts and 84 one-touch DSS keys. It suits executives and busy professionals who want smartphone-style navigation, AI noise cancellation and two USB ports for headsets, recording or wireless dongles. It is an open SIP phone that works with leading soft switches such as 3CX and BroadWorks, so check that your phone service supports it.
Key features
- 7-inch color touch screen: The 800x480 capacitive touch screen makes switching between pages and apps quick, and shows caller name, number and photo.
- AI noise cancellation: Yealink's AI noise cancellation, Acoustic Shield and Smart Noise Filtering filter out keyboard and office noise so callers hear you clearly.
- 84 one-touch DSS keys: Program 84 on-screen keys for lines, speed dials and BLF, and add up to 3 EXP55 expansion modules for up to 234 more.
- Two USB ports (USB-A and USB-C): Use any two of Bluetooth (via BT41), Wi-Fi (via WF50), a USB headset or USB call recording at the same time.
- Wide headset support: Works with wired RJ9 headsets, USB headsets, Yealink WH62/WH63 Portable DECT headsets and EHS wireless headsets through the EHS40 adapter.
- 10-way conferencing: Run a conference of up to 10 parties from the phone, without a separate bridge.
- Security and easy rollout: Linux 6.1, TEE hardware encryption, secure boot and TLS 1.3 protect the device, dual firmware images guard against a failed upgrade, and Yealink RPS supports zero-touch provisioning.
Choose your power option: the PoE version runs from a Power over Ethernet switch and has no power supply in the box. Choose "With power supply" if your switch does not provide PoE (adds the Yealink 5V/2A power adapter).

Specs are Yealink's, from its current data sheets. "None listed" means the data sheet names no such feature. Yealink uses SIP accounts and VoIP accounts to mean the same thing. Yealink lists the power adapter as optional on most models, so check that your switch has PoE or choose With power supply. Compare all T Series models
