From 30 Sep 2028, these Azure Communication Services offerings no longer function: Email, SMS, Advanced Messaging with WhatsApp, Chat, Chat for Teams Meeting Interop, Rooms, Number Management (Direct Offer), Direct Routing, Job Router, Web UI Library SDK and Mobile UI Library SDK. Voice/Video Calling SDK, Call Diagnostics, Call Automation, Audio Streaming, Call Recording and Closed Captions continue to function only when used with Microsoft Teams, and applications must be updated to the latest SDKs.
