CallProvider Class
Holds call and telephony session objects. In some cases the call may already be answered, that is in Established state, before being passed on to the workflow. In such cases, the AcceptCallActivity should not be used in the workflow since the call is already accepted. A custom activity should be used instead which must expose a CallProvider object as a property. The CommunicationsSequenceActivity in the workflow can then bind to the CallProvider property exposed by the custom activity.
