Sorry. Misread it. As Johannes suggested, there is a sample in the CallLogging implementation for using events. How to use them are there.

Basically there is a monitor instance that you can grab from: application.environment.monitor

And then you do things like:

monitor.subscribe and monitor.unsubscribe with the event definitions and handlers.
