OAuth 2.0-based Authentication for SIP Requests using Microsoft Entra ID

You can implement Microsoft Entra ID (formerly Azure Active Directory) to authenticate SIP User Agents (UA) of incoming SIP messages (including WebRTC), based on the OAuth 2.0 protocol.

Entra ID is Microsoft's cloud-based identity and access management service, designed for Internet-based applications. As Entra ID doesn't support OAuth Token Introspection, the device validates the received token using its embedded NGINX server, which simulates an OAuth 2.0 Introspection endpoint.

For configuring OAuth 2.0-based authentication of SIP messages, refer to the User's Manual.
