I currently use Packet8 service at home, have for a couple years now. It works fine but I am now diving in deeper.

I am also building a system for a small business, which will probably use Linksys equipment.

I am playing with softphones now.

ekiga (for Linux) could not get it going because the linux box has no mic input! (A Shuttle SB95)

Linksys SPA-400

This is an interesting device because it's open source. You can download the source tarball from the Linksys site.

It looks like it's based on Monta Vista Hardhat Linux

Asterisk

You might want to use an IDE/CF adapter that can hold two CF cards. This way you could stick in a smaller second card -say- 32 or 64MB and mount stuff like /etc/asterisk, /var/log, /var/run and voicemail etc on that one, possibly leaving the main card mounted read-only for most of the time.

Using Digium cards for FXS/FXO

Zaptel modules genzaptelconf -d Generates /etc/zaptel.conf and /etc/asterisk/zapata-channels.conf files.

Adjusting gain

1. Edit /etc/zaptel.conf to adjust receive and xmit gain levels.
2. Use ztmonitor channel to see levels during a call.
3. Use asterisk reload to change settings during a call.
