Choose Your Own Carrier

You can choose your own carrier in the Microsoft Teams Admin Center. You don't have to use Microsoft as your carrier. Atlantech Online is one of the few carriers available to choose from and we're integrated directly into Teams and Azure.


Number Management & Provisioning

Phone numbers can be selected out of the management portal. Your IT Administrator can assign phone numbers and policies through the Microsoft Teams Admin Center. Users assigned numbers can use Microsoft Teams for phone calls. 

Operator Connect delivers three primary benefits to SMBs and enterprise:


More Control for IT Admins

  • Self-manage users, numbers, call queues, auto-attendants, and more
  • Reduce the number of apps your IT admins must manage & support
  • Migrate to the cloud easily with API-driven, direct-to-carrier control and flexibility.

Simplifying Management & Adoption

  • Use Teams apps (desktop & mobile) for all calls
  • Easy-to-understand per user pricing
  • Employees use Teams for messaging, meetings, and calls, promoting rapid adoption with minimal need for onboarding & training.

Get the Most from Your M365 Investment
