plus overhead. You may be able to get by with less compression and
still fit within that modem's bandwidth.
I do not understand
why I should use compression. The regular phone
conversation is not compressed either.
Once more, I don't talk about VOIP.
The issue is how I can transfer voice from the computer to the phone
line with the help of the modem.
As I mentioned earlier, most modems won't do that. Those that will are
"soft modems" or "Win modems" and require the appropriate software. A
standard, hardware modem, which you said you had, connected via a serial
ports simply is not capable of what you want. This leaves the
alternative of voice over IP, which will require compression to fit
within the bandwidth of that modem. There is no magic that we can tell
you to perform that can make a modem do something that it wasn't
designed for. Perhaps if you were to mention the make & model of your
modem, we could provide further info.
BTW, "regular" phone conversation is often compressed, if you go through
a discount long distance carrier. It also is when you use a digital
