HD Sound

The T48 S features Yealink Otima HD Voice technology based on broadband frequency response, which is found on both the handset and the speakerphone for clear, noise-free sound.

Extraordinary screen

Its 7-inch colour touch screen makes all the difference. You can easily view your contacts, call logs, and perform your usual operations in the blink of an eye. In addition, it is possible to display up to 29 lines in monitoring at the same time, thus optimizing your communications.

Simplify your installation
