-Azure Communication Services are cloud-based services with REST APIs and client library SDKs available to help you integrate communication into your applications. You can add communication to your applications without being an expert in underlying technologies such as media encoding or telephony. Azure Communication Service is available in multiple [Azure geographies](concepts/privacy.md) and Azure for government.
+Azure Communication Services offers multichannel communication APIs for adding voice, video, chat, text messaging/SMS, email, and more to all your applications.

 Scenarios for Azure Communication Services include:
 
-- **Business to Consumer (B2C).** Employees and services engage external customers using voice, video, and text chat in browser and native apps. An organization can send and receive SMS messages, or [operate an interactive voice response system (IVR)](./concepts/call-automation/call-automation.md) using Call Automation and a phone number you acquire through Azure. [Integration with Microsoft Teams](./quickstarts/voice-video-calling/get-started-teams-interop.md) can be used to connect consumers to Teams meetings hosted by employees; ideal for remote healthcare, banking, and product support scenarios where employees might already be familiar with Teams.
-- **Consumer to Consumer (C2C).** Build engaging consumer-to-consumer interaction with voice, video, and rich text chat. Any type of user interface can be built on Azure Communication Services SDKs, or use complete application samples and an open-source UI toolkit to help you get started quickly.
