Alternative for GetAutomation() in the LyncClient

Hi,

We are developing an Lync client application, in this we need to dial a number to outside number the below code works fine when we are not using UI Suppression

LyncClient lyncClient = LyncClient.GetClient();
 var automation = LyncClient.GetAutomation();
 var conversationModes = AutomationModalities.Audio;
 var conversationSettings = new Dictionary<AutomationModalitySettings, object>();
 List<string> participants = new List<string>();
 var contact = lyncClient.ContactManager.GetContactByUri("tel:" + _TelephoneNumber);
 participants.Add(contact.Uri);
 automation.BeginStartConversation(AutomationModalities.Audio, participants, null, null, automation);

The same code while we are running the application in UI Suppression mode LyncClient.GetAutomation() throwing an error "Exception from HRESULT: 0x80C8000B". In forums found that GetAutomation() will not work in UISuppression mode. Is there any alternative way to achieve this functionality if so could anyone provide us sample code.

Thanks and Regards,
