I'm sure that you are intelligent enough to realize that your question cannot possbly be answered with specific information because you have provided no information upon which to base an answer.   However, here is some general infromation:

Go to the Windows Control Panel and get to the Modem diagnotics screen.  You will see AT0, AT1... including a bunch of info.  From that, you can learn the exact manufacturer and model of you modem and some other tidbits of information.

Next, go to the website of your modem's manufacturer.  There you will be able to download device drivers for your modem, including voice-capable codecs.  There may also be technical information on that site or perhaps at the site of the OEM chipset maker.

Thanks DanRollins for response ..

Basically i want to identify DSP that is inbuild with voice modem..
For that i want to use any API call in C/C++/VC++..
Is there any API call for that...

Thanjs again.......

DanRollinsCommented:
Sorry, I don't know of any such API call.  Modem voice handling is specific to the manufacturer of the modem.  They do not need to expose the DSP that they are using... They only need to provide a codec that can be used for input and output into their internal hardware.

Suppose i want to send data through voice modem..
then what happened data is transfered in compress format or actual data is transfered?

DanRollinsCommented:
Data transfer would be a separate layer withing the modem firmware.  Typically, the actual data transferred would  be compressed, but only if during the initial handshake with the remote host, the two modems had agreed upon a compression protocol.
