open verifiable calling

The open verifiable calling tag covers Microsoft’s use of a GSMA Foundry-backed framework to verify outbound calls from Azure Communications Services-based enterprise contact centers. The initiative focuses on giving legitimate customer-support and sales calls stronger caller ID credentials, helping recipients distinguish them from spam and reducing the risk that genuine business calls are blocked, mislabeled, or ignored. Coverage under this tag centers on the changing role of caller ID, cryptographic verification for enterprise communications, and Microsoft’s demonstration of the approach at MWC 2026. It is relevant to organizations using Azure contact-center services and monitoring trust, reachability, and identity across business phone calls.
