The Yealink T85W WiFi 6 VoIP/SIP Phone is a Prime Business Phone designed for busy executives and professionals, featuring an adjustable 5.5-inch colour LCD screen for comfortable viewing as well as built-in Bluetooth 5.0 and dual-band 2.4G/5G WiFi 6.

It uses a Hall switch handset for quiet operation in office environments, and Yealink's self-developed AI noise cancellation ensures superior audio quality during calls. Ultra-high-definition sound and support for broadband audio codecs provides realistic call audio. Running on Linux 6.1 with a TEE hardware encryption solution, it offers secure storage.

The T85W is also compatible with a wide range of Yealink headsets, supports configuration and upgrades through the LCD, and works with headsets featuring wearing detection for intelligent channel switching.
