Revolutionarily new design As Yealink 's SIP Phones continue to evolve, the SIP-T48S has been designed by pursuing ease of use with a scratch-resistant 7 inch touch screen, the T4 Series' signature metallic texture, non-slip rubber feet, and ergonomic recessed buttons. HD Audio Yealink Optima HD Voice refers to the combination of software and hardware design as well as the implementation of wideband technology to maximize acoustic performance. Coupled with advanced acoustic clarity technology such as full duplex, echo cancellation, and an adaptive jitter buffer, the SIP-T48S creates an amazing face-to-face experience. A rich visual experience for applications The SIP-T48S supports vast productivity-enhancing features such as a XML Browser, call forwarding, call transfer, 3-way conferencing, and support for a vast number of UC platforms for a superior UC experience.
