Description
The Yealink SIP-T85W is a modern smart business IP phone designed for executives, front-desk staff, office users, and businesses that need a high-end Yealink desk phone with strong audio quality, wireless flexibility, and enterprise-grade security. It belongs to the Yealink T8 Series, which focuses on combining a more modern hardware design with improved call clarity, stronger protection, and easier connectivity for professional office environments.
The phone features a 5.5-inch 960 × 480 color display in a slim desktop design with physical line keys and a business-oriented layout that is easier to use than a touchscreen model for users who prefer dedicated buttons. Yealink highlights the T85W as a smart desk phone with a larger display, emergency button, and antimicrobial materials, making it suitable for daily use in reception areas, management offices, and shared workspaces. It supports up to 16 SIP accounts, which makes it practical for multi-line office communication and professional VoIP deployments.
For connectivity, the SIP-T85W includes dual Gigabit Ethernet ports with PoE, built-in Wi-Fi 6, Bluetooth 5.0, USB-A and USB-C ports, and support for USB headsets, EHS, and expansion modules. On the audio side, Yealink equips it with AI Noise Cancellation, Optimized Acoustic Shield, and a 3W speaker to improve voice clarity in busy office environments. Security is also a key part of the device, with Yealink highlighting Trusted Execution Environment (TEE), secure boot, 802.1X, WPA3, TLS 1.3, and SRTP as part of the phone’s enterprise protection stack.
