* TMSDTMFObserver class
*
* This class provides callback mechanism for TMSDTMF listeners.
*
* Client class that wants to receive events from TMS must inherit from
* TMSDTMFObserver class and register itself with the TMSDTMF object.
*
* Functions declared in this class are called upon TMS events.
*
* The client must not do any blocking, or perform any CPU-intensive operations
* in the callback methods. It is recommended that the client saves event data,
* returns from this function immediately and if necessary, responds to
* the event in asynchronous way.
