Easy Call Control Initialization

To use call control functionalities via the Easy Call Control module, you must first initialize the module using the EasyCallControlFactory class. This class provides helper functions for taking control over IDevice instances and gives access to call control for the device.

The Easy Call Control module can be initialized with either Single Call or Multiple Call functionalities.

Option A) Single Call

To initialize the module with Single Call functionalities, see the following code sample.

using Jabra.NET.Sdk.Core;
using Jabra.NET.Sdk.Modules.EasyCallControl;
using Jabra.NET.Sdk.ToolsAndHelpers;

namespace InitializeECCSingleCall
{
    class ECCSingleCall
    {
        static async Task Main()
        {
            // Initialize the Jabra SDK
            try
            {
                var jabraCore = Init.InitSdk(new Config());

                // Set up for ISingleCallControl
                var easyCallControlFactory = new EasyCallControlFactory(jabraCore);

                // Whenever the core module detects new devices
                jabraCore.DeviceAdded.Subscribe(
                    async device =>
                    {
                        // Create Easy Call Control for single call handling
                        if (easyCallControlFactory.SupportsEasyCallControl(device))
                        {
                            var singleCallControl = await easyCallControlFactory.CreateSingleCallControl(device);

                            // Call single-call-control related functionality, for example
                            // Start a call, wait five seconds, end the call.
                            await singleCallControl.StartCall();
                            System.Threading.Thread.Sleep(5000);
                            await singleCallControl.EndCall();
                            // etc.
                        }
                    });
            }
            catch (JabraException ex)
            {
                Debug.WriteLine(ex.Message);
            }

            // Prevent the app from terminating, to allow for attaching and detaching.
            await Task.Delay(System.Threading.Timeout.Infinite);
        }
    }
}

To avoid repeating the code sample above in the documentation that follows, be aware that whenever a device's call control functionality is mentioned, it is assumed, that you have created an IMultiCallControl or ISingleCallControl instance as a prerequisite for any of the other operations.

Option B) Multiple Call

To initialize the module with Multiple Call functionalities, see the following code sample.

using Jabra.NET.Sdk.Core;
using Jabra.NET.Sdk.Modules.EasyCallControl;
using Jabra.NET.Sdk.ToolsAndHelpers;

namespace InitializeECCMultiCall
{
    class ECCMultiCall
    {
        static async Task Main()
        {
            // Initialize the Jabra SDK
            try
            {
                var jabraCore = Init.InitSdk(new Config());

                // Set up for ISingleCallControl
                var easyCallControlFactory = new EasyCallControlFactory(jabraCore);

                // Whenever the core module detects new devices
                jabraCore.DeviceAdded.Subscribe(
                    async device =>
                    {
                        // Create Easy Call Control for multi call handling
                        // Note different creation method from the previous example
                        if (easyCallControlFactory.SupportsEasyCallControl(device))
                        {
                            var multiCallControl = await easyCallControlFactory.CreateMultiCallControl(device);

                            // Call multi-call-control related functionality, for example
                            // Start a call, wait five seconds, put call on hold, wait, resume, wait, then end the call.
                            await multiCallControl.StartCall();
                            System.Threading.Thread.Sleep(5000);
                            await multiCallControl.Hold();
                            System.Threading.Thread.Sleep(5000);
                            await multiCallControl.Resume();
                            System.Threading.Thread.Sleep(5000);
                            await multiCallControl.EndCall();
                            // etc.
                        }
                    });
            }
            catch (JabraException ex)
            {
                Debug.WriteLine(ex.Message);
            }

            // Prevent the app from terminating, to allow for attaching and detaching.
            await Task.Delay(System.Threading.Timeout.Infinite);
        }
    }
