In order to be able to process the incoming calls you should provide us with a link to your web service implementing the IncomingCall( string, string, string, string ) method. As soon as a new phone call is received, an invocation with the data describing the connection will be sent to your service. The moment the invocation is received our service creates the Session and Phone objects to control the connection. Working with our service, first of all you should invoke the AcceptCall method (Phone object) to continue call processing, or RejectCall to reject the call. If you accept the call, process it as a usual phone connection, if you reject the call, just release resources.
Incoming calls processing model.
