Sorry to jump in late.

I'm looking into building * appliances.
Small footprint box with 4-6 10/100 ports and some variety of fxo/fxs or
T1 cards.  I'm currently in the process of specifying the boxes right
now.  Of course with some kind of web interface for configuration.  The
hardware requirements for a 1fxo/4fxs would be significantly less than
for the T1 cards, but My first focus was to spec for usage with T100P
and a channel bank.

If there's demand, I'll also look into specs for a lesser machine that
wouldn't support the T1 cards.
