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 T46S 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.
