Yealink T48U Datasheet
Distraction-Free HD Communications
The Yealink T4U series provides distraction-free communications with Yealink’s industry-leading Acoustic Shield Technology. Moreover, by leveraging Yealink’s Optima HD audio technology, and the addition of Opus to its broad audio codec list, Yealink’s new T4U series guarantees HD sound quality and a distortion-free communication experience.
* By supporting Opus, the Yealink T4U series delivers better audio quality in both high-bandwidth and poor network conditions, compared to other wideband or narrowband codecs.
Dual USB Ports, Strong Scalability
All T4U models are equipped with dual USB ports, meaning the entire series allows users to connect two Bluetooth dongles, Wi-Fi dongles, EHS40 headset adapters, USB headsets or USB disks at the same time. With dual USB ports, the new T4U series flexibly adapts to various scenarios and demands.
Color Expansion Module EXP43
Equipped with Yealink’s new EXP43 expansion module, the new T46U/T48U offers a full-colour experience, while the former EXP40 only supports greyscale colour mode. Moreover, when the EXP43 connects to the T43U greyscale phone model, the interface automatically switches to greyscale mode, making it more unified.
Efficient Deployment and Management
Yealink T4U series supports effortless mass deployment and Zero Touch Provisioning with Yealink’s Redirection and Provisioning Service (RPS) and Boot mechanism, making the device management labour-saving and efficient for the administrators.
