Yes. However, it is anything but easy.

When you say "dial-up" if you are referring to dial-up networking known
formally as Remote Access Services (RAS) then I think that if there is a
solution you will have to come up with one yourself.

However, if your modem uses the Unimodem TSP (telephony service provider),
and if it models its input and output units as Windows waveform devices,
then you can use the Telephony API (TAPI) to make or receive a telephone
call, ask TAPI to get the device ID of the remote party's "microphone ", and
use the waveform API (waveInOpen() etc ) to gain access to the audio stream.
That done, you can write a RIFF header to a file and append to it the
digitized audio samples that you read from the microphone.

It is not a task for the faint of heart. :-)

Regards,
Will

see TAPI
see the MSDN samples
you will find some pointers there.

Hi, I'm experimenting with the Serial Port in VB.NET 2005. Although it isn't that easy to get any feedback from my COM-port as I thought it would be... How can I read all the Data that the port sends back?

Automating date/time input for modem/router

by: Franc Zabkar | last post by:

My D-Link DSL-302G modem/router has a real-time clock whose settings are volatile. To avoid hand keying the date/time via the modem's JS interface, I wonder if there is a way to copy the JS code to the hard drive and modify it to automatically retrieve the PC's date/time. I could then add the hacked JS page to my browser's bookmarks. I've already successfully modified and adapted other modem menus, but I don't know how to go about this...
