Hi all
can u please tell me how can I detect the tones indicating that the line is
busy, ringing,or disconnected

I read on the msdn the function DetectTone

I tried to use it using julmar tapi3 as following:

TDetectTone[] TapiTones = new TDetectTone[1];

//busy tone

TapiTones[0] = new TDetectTone(0, 5000, 480, 620);

ActiveCall.DetectTones(TapiTones);

but I always get exception "Invalid tone ID"

can u help me please,

Thanks in Advance
