HD Audio Yealink Optima HD Voice technology combines cutting-edge hardware and software with wideband technology for maximum acoustic performance. Yealink's self-developed AI noise cancellation ensures better audio quality during calls. This open and highly versatile audio codec is designed to deliver superior HD audio quality compared to other wideband codecs, even in high network bandwidth environments.

High Security and Compatibility Yealink T85W adopts the latest network security technology, supporting SRTP and TLS call encryption, 802.1x media access control, MD5 and MD5-Sess based authentication, AES security profile, and other perfect security protection mechanisms to avoid hacker attacks. It is widely compatible with third-party SIP devices and leading SIP platforms. In addition, T85W supports a dual system function, which can back up your phone system in advance to avoid system crashes caused by upgrade failure, thus providing you with enterprise-level system protection. The T8X series also supports a security center function to ensure your phone is more secure, with high-sensitivity functions and data supporting user individual control and one-click disconnection.

Customizability and Scalability T85W not only has Gigabit PoE dual network ports for PoE power supply but also features two USB ports. You can choose based on your needs.
