how to hookoff a call from delphi

[AugustinMarc]

Hello,

 

I just started to wirk with the ClientSDK and so far, I can make a call :-)

Thats not really hard to code, but to terminate the call is on another hand.

 To establish a call is simple:

var
  aLine: integer;
Begin
aLine := ClientLineMgr1.DispSelectedLineNumber;
ClientLineMgr1.DispSimpleDial(ed_Dial.Text);
end:

 But to terminate will not work :

TClientLine(ClientLineMgr1.DispGetLine(aLine)).DispHookOff;

So, who knows how to terminate thel call?
