This topic demonstrates how to start an audio conversation using .NET managed code with Microsoft Lync 2010 SDK.

Prerequisites

For a list of prerequisites, see Walkthrough: Start an Instant Message Conversation .

Creating the Audio Conversation Application

To start an audio conversation, get a Microsoft.Lync.Model.Extensibility . . :: . . Automation object, create IEnumerable objects to contain a URI or a phone number, set instances of Microsoft.Lync.Model.Extensibility . . :: . . AutomationModalities and Microsoft.Lync.Model.Extensibility . . :: . . AutomationModalitySettings , and then call the Automation . . :: . . BeginStartConversation method.

To create the audio conversation application

  1. Sign in to Microsoft Lync 2010.

  2. In Microsoft Visual Studio development system, create a new Windows Forms application.

  3. Select .NET Framework 3.5 or 4.0 as the target framework. For more information, see the MSDN topic How to: Target a Specific .NET Framework.

  4. Add a reference to the assembly Microsoft.Lync.Model.

  5. In Form1.cs add the following using statement.

      Copy imageCopy Code 
    using Microsoft.Lync.Model;
using Microsoft.Lync.Model.Extensibility;

  6. In the Form1_Load event handler add the following code.

      Copy imageCopy Code 
    // Create the major API automation objects.
Automation _Automation = LyncClient.GetAutomation();

// Create a dictionary object to contain UiaConversationContext
data pairs.
Dictionary<AutomationModalitySettings, object>
_ModalitySettings = new Dictionary<AutomationModalitySettings,
object>();


// Create a generic List object to contain the URI to call.
// Edit this to provide a valid URI.
List<string> inviteeList = new List<string>();
inviteeList.Add("elise@contoso.com");

// Start the conversation.
IAsyncResult ar = _Automation.BeginStartConversation(
	AutomationModalities.Audio
	, inviteeList
	, _ModalitySettings
	, null
	, null);

_Automation.EndStartConversation(ar);

  7. Build and run the application.

  8. Hear the ringtone from Microsoft Lync 2010 on the calling computer. See the accept call request on the computer you called.
