How to press virtual hangup key

[Jogi]

hi there,

i try press the hangup key in my application, to hangup outgoing calls.
Can anyone tell my whats wrong with my code:

private const byte VK_HANGUP = 0x73;

private const uint KEYEVENTF_EXTENDEDKEY = 0x0001;

[DllImport("Coredll.dll")]
public static extern void keybd_event(byte bVk, byte bScan, uint
dwFlags, uint dwExtraInfo);

keybd_event(VK_HANGUP, 0, KEYEVENTF_EXTENDEDKEY, null);

The code runs without errors, but also without success. Need help ...
please

Regards
Jogi
