Cisco Cisco Computer Telephony Integration Option 9.0 Developer's Guide

The client application should hold a reference to the Session object as long as it 
is in use, but the client programmer must release the last reference to the object to 
prevent a memory leak when the object is not longer needed.

During application cleanup, the Session object must only be disposed by invoking 
the CCtiOsSession::Release() method. This will ensure proper memory cleanup

.

For example:

m_pSession->Release();

Before making any method calls with the Session instance, you must set the 
session as an event listener for the desktop application and subscribe to events.

The following lines show this in 

rSession.AddEventListener(this, 

CtiOs_Enums.SubscriberList.eAllInOneList);

In this example, the session is adding the containing class, the desktop 
application, as the listener, and using the eAllInOneList field in the 
CtiOs_Enums.SubscriberList class to subscribe to all events.

To set connection parameters:

Create an instance of the Arguments class.

Set values for the CTIOS servers, ports, and the heartbeat value.

When setting values, use the String key fields in the CtiOs_IKeywordIDs 
interface, as shown in the example below.
