The history of Microsoft Teams Voice Engineer certification

The Microsoft Teams Voice Engineer certification is designed to validate the competency of a professional engineer to design, test and deploy voice solutions with Microsoft Teams. It is a significant step in the continuing evolution of collaboration and communication technologies. I have been working on the Microsoft Teams project at Microsoft for a year now. In this time, my team has had the opportunity to work across all aspects of the product, utilizing cutting-edge technologies such as Azure Active Directory, Cortana Intelligence Suite, and Cognitive Services. I've learned a great deal from this experience, but one of the most interesting challenges I've had to tackle was designing and building out the system that would allow us to scale our voice model through our global footprint. The architecture for this solution was actually much easier than I expected it would be, which made it exciting to put together.

There were two primary reasons for this:

First, Teams leverages some of the core infrastructures already in place for Skype for Business Online; second, Microsoft Teams is built on top of Office 365 Groups and shares many components with SharePoint Online (for example, most of our routing logic is implemented in .NET Core).
These facts enabled me to leverage a lot of existing code and infrastructure while building out my services.
