OAuth 2.0-based Authentication for SIP Requests using Azure AD

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

Azure AD is Microsoft's cloud-based identity and access management service, designed for Internet-based applications. As Azure AD 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.
