Microsoft Teams is growing up fast.

“We’re announcing a new vision for intelligent communications to transform calling and meeting experiences by bringing comprehensive voice and video capabilities into Teams, along with cognitive and data services, and insights from the Microsoft Graph,” said Kirk Koenigsbauer, corporate VP for the Office team in a blog post.

Microsoft’s chat-based team collaboration software is inheriting the calling and virtual meetings capabilities currently found in Skype for Business.

The Teams instant messaging platform – which is bundled with the company’s Office 365 productivity suite – was launched only six months ago as a rival to Slack. According to Microsoft, there are now 125,000 organizations using the software globally.

Teams is already running on Skype’s cloud-based infrastructure for video and audio calls, which Microsoft is “evolving rapidly.”
