 # Teams Interoperability: Calling and chat
 
 > [!IMPORTANT]
-> Calling and chat interoperability is in private preview, and restricted to a limited number of Azure Communication Services early adopters. You can [submit this form to request participation in the preview](https://forms.office.com/r/F3WLqPjw0D) and we will review your scenario(s) and evaluate your participation in the preview.

You must be a member of the Azure Communication Service TAP team.
 
 As part of this preview, the Azure Communication Services SDKs can be used to build applications that enable bring your own identity (BYOI) users to start 1:1 calls or 1:n chats with Teams users. [Standard Azure Communication Services pricing](https://azure.microsoft.com/pricing/details/communication-services/) applies to these users, but there's no extra fee for the interoperability capability itself. Custom applications built with Azure Communication Services to connect and communicate with Teams users or Teams voice applications can be used by end users or by bots, and there's no differentiation in how they appear to Teams users in Teams applications unless explicitly indicated by the developer of the application with a display name.

 ## Get Teams user ID
 
 To start a call or chat with a Teams user or Teams Voice application, you need an identifier of the target. You have the following options to retrieve the ID:
-- User interface of [Azure AD](../troubleshooting-info.md?#getting-user-id) or with on-premise directory synchronization [Azure AD Connect](../../../active-directory/hybrid/how-to-connect-sync-whatis.md)
+- User interface of [Azure AD](../troubleshooting-info.md?#getting-user-id) or with on-premises directory synchronization [Azure AD Connect](../../../active-directory/hybrid/how-to-connect-sync-whatis.md)

 ## Calling
-With the Calling SDK, a Communication Services user or endpoint can start a 1:1 call with Teams users, identified by their Azure Active Directory (Azure AD) object ID. You can easily modify an existing application that calls other Communication Services users to instead call a Teams user.

 ## Privacy
 Interoperability between Azure Communication Services and Microsoft Teams enables your applications and users to participate in Teams calls, meetings, and chats. It is your responsibility to ensure that the users of your application are notified when recording or transcription are enabled in a Teams call or meeting.
 
-Microsoft will indicate to you via the Azure Communication Services API that recording or transcription has commenced and you must communicate this fact in real time to your users within your application's user interface. You agree to indemnify Microsoft for all costs and damages incurred as a result of your failure to comply with this obligation.
