Key Features and Benefits
This premium phone is for executives and professionals who expect high phone performance
and a superior Skype for Business-tailored experience.
With its 7-inch, 800x480-pixel backlit touchscreen and a modern interface, the T48S offers users
simple one-click access to Skype for Business features while lowing the learning curve thanks to
its familiar and friendly user interface. The SIP-T48S is also with Yealink’s Optima HD Voice
technology and SILK speech codec for unparalleled audio clarity. Phone users will think they are
sitting in the same room with one another. The T48S provides added flexibility for executives
and professionals with its USB Bluetooth connectivity and its ability to switch calls to mobile
phones. With the Yealink EXP40 Expansion Module, the phone extends up to 240 contacts.
Optima HD Audio
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 band-
width, 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 expan-
sibility with Bluetooth, Wi-Fi, USB recording and USB headset 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 custom-
ers 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.
