Key Features and Benefits

Optima HD Voice

Yealink Optima HD Voice technology combines cutting-edge hardware and software with wideband technology for maximum acoustic performance. As a speech codec for real-time, packet-based voice communications, SILK, is designed to perform a higher HD audio quality which provides scalability in several dimensions and is highly scalable in terms of audio bandwidth, network bit rate, and complexity. And its hearing aid compatible (HAC) handset helps the person who is with hearing loss to hear the voice more clearly.

High interoperability

The T48S is fully compatible with Skype for Business and Office 365, making for a rich and capable ecosystem for executives and professionals. Simply sign in with your Skype for Business account; your presence status and contacts immediately sync with the SFB client. The T48S even lets users synchronize Outlook Calendar meeting schedules in real-time- by simply clicking to join a meeting. With an all-new USB port, the T48S boasts unparalleled functionality and expansibility with Bluetooth, Wi-Fi (pending) and USB recording (pending) features.

A rich visual experience

Featuring a large touch panel and modern Skype for Business interface enables richer visual presentation and easier navigation of the menu. Pin your favorite contacts directly on the home screen, easily arrange them, and place a call to them with just a tap. Supporting Microsoft’s Skype for Business Server in-band provisioning and in-band configuration management enables a carefree configuration and easier-than-ever mass deployment. Automatically deploy on a variety of servers- http, https, tftp and ftp. Yealink’s T48S can even be pre-installed with Yealink’s premium software for Skype for Business prior to shipping, meaning plug-and-play for customers immediately after unboxing. Furthermore, a unified firmware and auto-p template that applies to all T4S phone models (T41S, T42S, T46S and T48S), saves even more time and costs for businesses, as well as simplifies the management and maintenance.
