Subject: Playback over modem
Reply | Reply to author | Forward | Print | Individual message | Show original | Report this message | Find messages by this author
Hi,
For months I have tried to dial a number and play a wav file using this
connection. I have tried Julmar's ITAPI and also Tapi3lib.
I can call the number but I can not create a terminal. Using Julmar's api I
try;

 TCall
myCall=MyAddress.CreateCall("0",LINEADDRESSTYPES.PhoneNumber,TAPIMEDIATYPES .AUDIO)
TTerminal t=myCall.RequestTerminal(TTerminal.FilePlaybackTerminal,
TAPIMEDIATYPES.AUDIO, TERMINAL_DIRECTION.TD_RENDER)

in this code TTerminal object always returns null.

Before that I tried using Tapi3Lib directly;

         ITAddress oAddress;      
         ITMediaSupport ims = (ITMediaSupport)oAddress;
         ITTerminalSupport its = (ITTerminalSupport)ims;  //Error

When I try to crate ITTerminalSupport I get "unable to assign... Such an
interface isn't supported" error.

I'm using Agere Systems HDA modem. As I said I got no problem calling. Is
the problem about my modem's audio support? I also tried the codes on a few
laptops and I got same errors.

Thanks in advance
Halil

Hi,
I use below code, and can Play wav file via phone line:

private void btnPlay_Click(object sender, EventArgs e)
        {
            Object[] playList = { "C:\\myfile.wav" };
            ITTerminal PLyTerminal=
bcc.RequestTerminal(TAPI3Lib.TapiConstants.CLSID_String_FilePlaybackTermina l,
TapiConstants.TAPIMEDIATYPE_MULTITRACK, TERMINAL_DIRECTION.TD_CAPTURE);
            ITMediaPlayback MediaPlay=(ITMediaPlayback)PLyTerminal;
            MediaPlay.PlayList = playList;
            ITMediaControl MediaControl = (ITMediaControl)MediaPlay;
            bcc.SelectTerminalOnCall(PLyTerminal);
            MediaControl.Start();
        }

and use below code for dial:
private void btnCall_Click(object sender, EventArgs e)
        {
           bcc = (ITBasicCallControl2)ln.CreateCall(textBox1.Text,
TapiConstants.LINEADDRESSTYPE_PHONENUMBER, TapiConstants.TAPIMEDIATYPE_AUDIO);

            bcc.Connect(false);
            }

Halil,
are you using a voice modem or only a fax/data modem?
The latter won't work for this.

bcc.RequestTerminal(TAPI3Lib.TapiConstants.CLSID_String_FilePlaybackTermina l,
TapiConstants.TAPIMEDIATYPE_MULTITRACK, TERMINAL_DIRECTION.TD_CAPTURE);

And For Andreas's question. How can I understand if a modem supports voice

Thanks & Regards

Halil, you are welcome.

You may want to try my TotoŽ Tool WaveDevice and see whether it reports any
wave devices (in / out) associated wih your modem:
http://www.i-b-a-m.de/Andreas_Marschall's_Toto_Tools.htm#_TotoŽ_Tool_WaveDevice
If i doesn't then your modem isn't (installed as) a voice modem.
