Support outbound public switched telephone network calling for faculty users through Microsoft Teams with a pay-as-you-go calling service scoped to Country Zone 1 in the United States. This offering provides the calling-plan component for organizations that need consumption-based voice usage instead of a fixed monthly pool of included calling minutes. Assign the service to eligible faculty users within the organization’s Microsoft tenant to support Teams-based calling workflows. The faculty designation matters when matching education licensing eligibility and user assignment. Country Zone 1 identifies the United States calling region for this service, helping administrators select a plan that corresponds to the intended calling geography. Pay-as-you-go treatment makes calling charges dependent on actual usage, which can suit user populations whose calling volumes differ substantially between departments, terms, or roles. Microsoft part number 3CCBA685AD5D identifies the faculty, United States Country Zone 1 version of Teams Calling Plan Pay-as-you-go. Within the Teams Calling Plan range, its distinguishing attributes are the education-focused faculty audience, the US geographic scope, and consumption-based calling. It is a digital service entitlement rather than physical equipment, so deployment occurs through tenant administration and user assignment rather than device installation.
