Remarks
These events represent the responses to the asynchronous requests defined in the IUccSubscription interface. An application must implement this interface and advise an IUccSubscription object of the implementation if it is interested in receiving the status of completion of the subscription operations. This is a dispinterface. Its members define the event handlers for the events raised by an IUccSubscription object. To catch the events, a UCC API client must implement these event handlers and advise the event source of the implementation if it is interested in receiving the events. To prevent memory leaks, the client should unadvise the events when it is no longer interested in the events. Trace and Handle Errors in Unified Communications Client API

The following example creates a subscription using the supplied parameters and advises for events on the new subscription.

/// <param name="pSubContextPropertyName">context property name</param>
/// <param name="pSubContext">context value</param>
/// <param name="pEventSink">Class instance implementing event handler for subscription events</param>
/// <returns>new IUccSubscription with context</returns>
