Not able to receive create conference event from Lync client (on Meet now)

Hi,

We are using UCMA 5.0(V6.0.9319.0) and Lync Server 2015(V6.0.9276.0). From the Lync client whenever Meet now is clicked, we expect some event to be triggered on the application layer which is developed using UCMA 5.0.

We are pretty much naive to UCMA development and below is the code we have tried on the application layer:

ProvisionedApplicationPlatformSettings serverPlat = new ProvisionedApplicationPlatformSettings("ConferenceOnTheGo", "urn:application:ConferenceOnTheGo");

_platform = new CollaborationPlatform(serverPlat);

_platform.EndStartup(_platform.BeginStartup(null, null));

 ApplicationEndpointSettings endpointSettings = new ApplicationEndpointSettings("sip:ConferenceOnTheGo@dc.com",
                    "10.203.229.164", 5061);

endpointSettings.IsDefaultRoutingEndpoint = true;

 _endpoint = new ApplicationEndpoint(_platform, endpointSettings); 

_endpoint.EndEstablish(_endpoint.BeginEstablish(null, null));

 _endpoint.InnerEndpoint.SessionReceived += OnInnerEndpointSessionReceived; // we are receiving this event

_endpoint.RegisterForIncomingCall<AudioVideoCall>(OnAudioVideoCallReceived); // we are not receiving this event.

_endpoint.ConferenceInvitationReceived += ConferenceInvitationReceived; // we are not receiving this event.

Please suggest if we are doing it rightly or missing anything in getting CreateConference Event on our UCMA apllication layer
