Developers play a crucial role in leveraging these features and integrating them with existing systems to create a unified communication solution. Let's explore some of the tools and APIs available for developers to build smart calling solutions with Microsoft Teams.

Microsoft Graph API for Calling

The Microsoft Graph API is a powerful tool that enables developers to access and manipulate data within Microsoft 365 services, including Teams. By using the Graph API for calling, developers can perform various tasks such as initiating calls, managing call records, retrieving call details, and recording calls. Some of the key functionalities provided by the Graph API for calling include:

Java Code Sample: Initiating a Call With Microsoft Graph API

To initiate a call using the Microsoft Graph API, you'll need to set up the necessary authentication and make an HTTP POST request to the /communications/calls endpoint. Here's a Java code sample using the Microsoft Graph SDK to initiate a call:

Java
  
import com.microsoft.graph.authentication.IAuthenticationProvider;
import com.microsoft.graph.authentication.TokenCredentialAuthProvider;
import com.microsoft.graph.models.*;
import com.microsoft.graph.requests.GraphServiceClient;
import java.util.Arrays;

public class TeamsCallInitiator {

    public static void main(String[] args) {

        String accessToken = "your_access_token_here"; // Replace with your access token
        IAuthenticationProvider authProvider = new TokenCredentialAuthProvider(Arrays.asList("https://graph.microsoft.com/.default"), () -> accessToken);
        GraphServiceClient graphClient = GraphServiceClient.builder().authenticationProvider(authProvider).buildClient();

        Call call = new Call();
        call.target = new InvitationParticipantInfo();
        call.target.identity = new IdentitySet();
        call.target.identity.user = new Identity();
        call.target.identity.user.id = "user_id_here"; // Replace with the user's ID
        call.mediaConfig = new ServiceHostedMediaConfig();
        call.requestedModalities = Arrays.asList(Modality.AUDIO, Modality.VIDEO);
        Call newCall = graphClient.communications().calls()
                .buildRequest()
                .post(call);
        System.out.println("Call initiated: " + newCall.id);
    }
}


Replace the your_access_token_here and user_id_here placeholders with your access token and the user's ID, respectively.

Java Code Sample: Recording a Call With Microsoft Graph API

To record a call using the Microsoft Graph API, you'll need to make an HTTP POST request to the `/communications/calls/{id}/record` endpoint, where {id} is the call ID. Here's a Java code sample using the Microsoft Graph SDK to start recording a call:

Java
  
import com.microsoft.graph.authentication.IAuthenticationProvider;
import com.microsoft.graph.authentication.TokenCredentialAuthProvider;
import com.microsoft.graph.models.*;
import com.microsoft.graph.requests.GraphServiceClient;

import java.util.Arrays;

public class TeamsCallRecorder {
    public static void main(String[] args) {

        String accessToken = "your_access_token_here"; // Replace with your access token
        String callId = "call_id_here"; // Replace with the call ID
        startRecording(accessToken, callId);
    }

    public static void startRecording(String accessToken, String callId) {

        IAuthenticationProvider authProvider = new TokenCredentialAuthProvider(Arrays.asList("https://graph.microsoft.com/.default"), () -> accessToken);
        GraphServiceClient graphClient = GraphServiceClient.builder().authenticationProvider(authProvider).buildClient();

        RecordOperation recordOperation = new RecordOperation();
        recordOperation.status = OperationStatus.NOT_STARTED;

        RecordOperation startedRecording = graphClient.communications().calls(callId).record()
                .buildRequest()
                .post(recordOperation);

        System.out.println("Recording started: " + startedRecording.id);
    }
}


Replace the your_access_token_here and call_id_here placeholders with your access token and the call ID, respectively.

Integration With Third-Party Services

Integrating Microsoft Teams with third-party services can significantly enhance the calling experience for users. Some popular integration options include:

Building Custom Applications With Teams Toolkit

The Microsoft Teams Toolkit is a set of tools and resources designed to help developers build custom applications for Teams. Using the toolkit, developers can create custom calling experiences by embedding Teams calling features within their applications, including call recording. Some of the key components of the Teams Toolkit include:
