Notifies the application about device specific events occurring on a line, address, or call.

Namespace: Traysoft.AddTapi
Assembly: Traysoft.AddTapi (in Traysoft.AddTapi.dll) Version: 6.0.0.1110
Syntax
Copy
public static event TapiDeviceSpecificEventHandler DeviceSpecific

Value

Type: Traysoft.AddTapiTapiDeviceSpecificEventHandler
Remarks

DeviceSpecific event is used by a telephony service provider to notify the application about device specific events. The application must negotiate device specific extension version using NegotiateDeviceSpecificExtensionVersion(UInt32, UInt32) before opening the line to receive DeviceSpecific events. The meaning of the event and its parameters are device specific. Please refer to the TAPI documentation for the telephony hardware to find out about device specific functionality supported by the telephony service provider.

Note Note
In Windows Forms and WPF applications AddTapi.NET executes the handler of this event on the main thread of the application (the thread that called Initialize(String)). It is safe to access Windows Forms or WPF controls from the event handler without using Invoke mechanism.
Examples
The following code shows how to handle DeviceSpecific event.
Copy
TapiApp.Initialize("MyApp");
TapiApp.DeviceSpecific += OnDeviceSpecific;
...

void OnDeviceSpecific(object sender, TapiDeviceSpecificEventArgs args)
{
    Console.WriteLine("Device specific event on line {0}", args.Line.Name);
    Console.WriteLine("Param1={0}, Param2={1}, Param3={2}", args.Param1, args.Param2, args.Param3);
}
