/**
*
* @class    CAnsPhoneCallMaker AnsPhoneCallMaker.h
* @brief    This class makes a phone call
*
*    An RCall handle is required to make the call. In order to open it, we need a handle on
*    an RLine handle. This will have been opened before this class is constructed and is passed
*    in as a parameter of the constructor.
*    
*    The MakeCallL() function is called in order to make the call.
*    This uses one of the RCall.DialL() functions. The RunL() function is called when the number 
*    has been dialled. At this point, we ask the RCall handle to notify us if a change occurs to 
*    its status, using NotifyStatusChange(). This will result in the RunL() function being
*    called when the status has changed. If the status is hanging up or idle, then we close the
*    RCall handle.
*    The observer is updated when the call has been hung up
