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
