Skype for Business Server provides a unified communications solution for voice, chat, and video communication, as well as “enterprise voice” capabilities to integrate with or replace on-premises private branch exchange (PBX) telephone systems. It works with client applications for desktop PCs and mobile devices, and it provides a limited browser interface for conference attendees. However, Teams is Microsoft’s focus for unified communication and collaboration. Although the latest version, Skype for Business Server SE, will be supported until at least 2035, it’s unlikely to receive more than quality, bug, and compatibility updates.
