Your Operator Connect journey starts in the admin center of Microsoft Teams. If you do not have MS Teams yet in your organisation, you can purchase any Microsoft/Office 365 package through Enreach or one of our resellers.
With MS Teams admin center, you can choose to have Enreach as your carrier. By choosing Enreach you allow phone numbers and SIP trunks ordered at Enreach to become available in MS Teams. Then you can assign these numbers to the MS Teams users to make and receive telephone calls.
