Cisco Cisco Computer Telephony Integration Option 9.0 Developer's Guide

E_CTIOS_MISSING_ARGUMENT - The Arguments parameter did not 
contain values for both CTIOS_CTIOSA and CTIOS_CTIOSB. At least one 
of these values must be provided. The connection failed. No events are fired.

E_CTIOS_IN_FAILOVER - A previous connection attempt failed and the 
CIL is currently in failover and attempting to establish a connection. This 
continues until a connection is established, at which point the CIL will fire an 
OnConnection() event indicating that the previous Connect() method has 
succeeded. To attempt to connect again with different parameters, the 
application must first use the Disconnect() method.

E_CTIOS_SESSION_NOT_DISCONNECTED - The Session is not 
disconnected (i.e. a previous Connect() method is in progress, or the Session 
is already connected). The application must call the Disconnect() method 
before attempting to establish another connection. The CIL may fire an 
OnConnection() event for the to previous call to the Connect() method if the 
connection was in progress, but will not fire one corresponding to this method 
call. 

E_CTIOS_UNEXPECTED - There was an unanticipated error. The 
connection failed. No events are fired. 

Once the application receives a Connect return code of CIL_OK, it should not call 
Connect again on that session until it receives an OnConnectionClosed event after 
a call to Disconnect.

If you are using CTI OS in an IPCC Enterprise environment, you can configure 
the agent to automatically log in again in the event of a failover.

To configure the agent to log back in automatically, add the 
CTIOS_AUTOLOGIN keyword with the value “1” to the Arguments instance 
used to configure the agent:

rArgs.SetValue(CtiOs_IKeywordIDs.CTIOS_AUTOLOGIN, “1”);

For more information on logging in an agent, see page 4-42.
