    88Subclassing the Call Class 
    99------------------------------------ 
    10 To use the Call class, normally application SHOULD create its own subclass, such as::

    3133Making Outgoing Calls 
    3234-------------------------------------- 
    33 Making outgoing call is simple, just invoke ​makeCall() method of the Call object. Assuming you have the Account object as acc variable and destination URI string in dest_uri, you can initiate outgoing call with the snippet below::

    4751Incoming calls are reported as ​onIncomingCall() of the ​Account class. You must derive a class from the Account class to handle incoming calls.

    5763    } 
     
    6773Call disconnection event is a special event since once the callback that reports this event returns, the call is no longer valid and any operations invoked to the call object will raise error exception. Thus, it is recommended to delete the call object inside the callback.

    69 The call disconnection is reported in ​onCallState() method of ​Call and it can be detected as follows::
