Optima HD Voice

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

Further outfitted with directory synchronization, visual voicemail management, Boss/Admin and more, it raises the bar for productivity to new heights. With an all-new USB port, the T42S boasts unparalleled functionality and expansibility with USB recording and USB headset features

Effortless Deployment

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 T42S 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.
