What's next

“The technology has leveled the playing field. It hasn’t leveled execution.”

That's the work ZIRO is focused on: combining software, automation and operational accountability so enterprises and partners get more out of Microsoft Teams Phone, and keep getting more out of it.

Congratulations, Steven, and thank you again to UC Today.
