How is Operator Connect different from Microsoft Calling Plans?

Operator Connect routes calls through a Microsoft-certified third-party carrier that manages the voice infrastructure, while Microsoft Calling Plans use Microsoft itself as the carrier. Both add PSTN calling to Teams, but they differ in who controls the network, pricing structure, support model, and deployment flexibility.

With Microsoft Calling Plans, Microsoft acts as the phone carrier and charges per its own rate card with metered minutes. With Operator Connect, the organization chooses a certified carrier that provides per-user or shared-channel pricing, often with unlimited local and long-distance calling included. The support experience also differs significantly because Calling Plan issues go through Microsoft's standard support channels, while Operator Connect issues go directly to the carrier. Carriers like Atlantech Online provide live engineer support in under 10 minutes, 24/7/365, which is a faster path to resolution than Microsoft's tiered support queues. Operator Connect also gives organizations more flexibility on number management, E911 configuration, and pricing models than Calling Plans typically allow.
