Enable Teams Calling for Your Microsoft 365 Environment

If you already use Microsoft 365, you can use Teams Calling from Atlantech Online to simplify things for employees and your IT team. 

Teams Calling is a Microsoft product, so why not just go through them?

Surely they know the best and have large customer service teams to help when I have a question.
But if you value fast, professional support, that may not be best route to go.

"Switching to Teams Calling was so timely and efficient with Atlantech Online!

We were hesitant to switch over before the license change, but Atlantech Online was always available to answer any questions that we had and always responded in a timely manner, and professionally managed the cutover and then accommodated the license change."

I 10/10 recommend this company.

“Very happy with our decision to rollout Teams Phone and Cloudfax with Atlantech as our partner. There were a few bumps along the way, as with any rollout. But as always, the Atlantech Online team was very responsive, agile, and quick to act.”
