Wav and Mscomm!! URGENT

Hi
I am developing an application, Which Pickup's the call using Mscomm and my modem, (i am using AT Commands like ATH1 & ATH0), Now i want that when i click Accept Call button which wil usually accept the incoming calll and send AT commands to modem (ATH1), then i want to play a wav or mp3 file to modem which the Caller can hear,

Anyone have any demo for that, or any idea, concepts etc...

Thanks in Advance, Its Urgent

Is this thread related to this thread?

No thats a different topic,,im ust asking for Outputting Wav file using AT Commands or any diff method

Anyone Please, Have Some Info ????

Try this thread. Maybe it'll get you started. Post #6 has code to record the telephone audio - study that and maybe uyou can figure out how to reverse it.

Of course you have to have a voice modem to do it in either direction.
