This property has the following sub-properties:

Available
DeviceID
DeviceClass

Declaration

property WaveOut: ThbTapiRelatedWaveDevice;

ThbWaveOut.DeviceID

Available (Boolean)

Availability:

Design-Time: None / Run-Time: Read

This property indicates if the call has an associated wave output device. Usually the call has to be in the connected state before an associated wave device is available.

Example

procedure TForm1.hbTapiLine1Connected(Sender: ThbTapiLine; Call: ThbTapiCall);
begin
   if Call.WaveIn.Available then
begin
  PlayWave(Call.WaveIn.DeviceID);
end;

DeviceClass (String)

Availability:

Design-Time: None / Run-Time: Read

The value of this property is "wave/out". This is the only valid value at this time. When ThbTapiCall.WaveIn.Available or ThbTapiCall.WaveIn.DeviceID is called, this string is used to check if a device of the given class is assocaited with the TAPI Call device resp. to get the DeviceID.

DeviceID (Integer)

Availability:

Design-Time: None / Run-Time: Read

This is the ID of the wave output device which is associated to the call. You should prove the value of Available before ThbTapiCall.WaveOut.DeviceID otherwise an exception could raise.
