> I am using the MSComm control to dial up phone (by modem). I wish to dialup a phone and when the other site is pick up the phone, my pc can continue to play the pre-recorded wave file, so that the other site can hear the sound through the line (Notes : the sender is modem,the receiver site is a phone, not modem.)
> Do any one know how to do it ? I had succeed to dial up the phone, but the problem is don't know how to play the wave and send out through the receiver site ? Any API can i use ?
>thanks !

I don't know how you could detect an answer without a hardware handshake, but you could always have the users call your program instead. As soon as the server picks up it could start playing the .wav file.
