How does number porting work with Operator Connect?

Number porting transfers existing phone numbers from a previous carrier to the Operator Connect provider with no service interruption. The certified carrier submits a port request to the losing carrier, validates the numbers, and provisions them in the Microsoft Operator Connect platform so they appear in the Teams Admin Center for assignment.

The porting timeline depends primarily on the losing carrier's release process. Simple ports (a few numbers from a cooperative carrier) can complete in days. Large or complex ports (hundreds of numbers, multiple rate centers, or carriers that delay releases) can take weeks. During the transition, the Operator Connect carrier coordinates the cutover to minimize downtime, ideally achieving zero interruption for end users. Atlantech Online handles the entire porting process as part of its operator-led onboarding and charges no porting fees. Once the numbers are active in the Operator Connect platform, they appear in the Teams Admin Center where administrators assign them to users, configure call routing, and manage emergency addresses through the same interface they use for all other Teams administration.
