PCI Telephoney recorder card output detection C or C++

I am using WINDOWS and the card vendor didn't provide any information or SDK about the telephony recorder card is it possible to extract voltage change or any output information from that card

I already tried the MS TAPI no use i think its not supported with that card !!

Send the card back to the card vendor, demand your money back.

If they're not going to tell you anything, it is essentially useless.

I agree.... and it's becoming more common.

You buy a card or usb gadget and it's tied to a single program that is both driver and user code combined and it's useless beyond that. Of course the only app is always junk... :mad:
