Yes, i`d like to use it (modem) with major direction (internet and net gateway) and as autoanswering machine ('cause it's voice modem). also, it can be gateway for VoIP. Thousands of applies

But problem of wiring for both analog and digital audio still exists, i just don't know how to solder this

I don't think you'll find a small enough data/voice modem. You seem to have found a data modem, but you'll need a separate modem to handle audio out to the line, and this will probably, as said, be able to be handled by the built in sound card, but you'll need some extra circuitry to interface it with the line. DO NOT try to wire it directly to the phone line, the ringing signal is something like 40 volts.

Note my post prior, with such a design, including all elements needed to use the UART!!!
