The goal is to listen several telephone lines and record conversations. The
basic components would be

Line -> DAA -> ADC -> TCP/IP/Ethernet -> PC.

I would like to know whether there are better solutions; may be the
recorders are already existing with PC interface. The most complex thing I
feel is PC interfacing. May be it is better to use USB or something else
instead of Ethernet. I'm sure that USB has a special class (thus drivers for
major platforms) for telephony but not sure in success.

Very much thank you for any advice.

I have 2 sound cards, recording 2 stereo channels at the time is possible,
so plug 4 mono in the back of the PC, I take from voice modem for example,
or little transformer with cap on phone line.
So much simpler, in Linux more soundcards should be possible,
also I have not tried but the Creative SB live I use has more then one
/dev/dsp in use, so perhaps recording 4 mono channels or more with one card
is also possible.
