The Yealink T57W is a Linux based premium-level IP phone with a 7" pixel color touch display that is fully adjustable. The T57W supports 16 SIP accounts and features built-in Bluetooth and Wi-Fi.
The T5 series features Yealink's Acoustic Shield technology for distraction-free voice clarity. The technology uses multiple microphones to create a virtual shield between the speaker and the person on the other line. When enabled, it blocks out or mutes sounds that are considered to be outside the shield so that the person on the other end hears the speaker clearly.
