DLRegisterType2CallDeltas
The DLRegisterType2CallDeltas() routine is used to request Call Delta information.
Parameters
• pbxh - A number used to identify the system. This is the user-supplied parameter used to
connect to Dev Link in the call to DLOpen().
• cb - The address of the callback function that will receive real-time events. Only one callback can
receive real-time events at one time, and if this parameter is NULL, then real-time events will no
longer be sent to the application.
Return value
• This routine may return:-
• 0 = DEVLINK_SUCCESS
•
1 = DEVLINK_UNSPECIFIEDFAIL - Returned in the event of an error.
• 2 = DEVLINK_LICENCENOTFOUND - If no CTI licence is activated on the IP Office
system.
