Also FXO devices require certification to be used in many countries,
and this is not cheap, the manufacturer has to pass this cost on to
someone.

But if you want 24 or 30 lines, a Digium Wildcard T100P/E100P is only $25/$20 per line
or for 96/120 lines, a T400P/E400P is only $16/$13 per line.

For smaller systems, you'd have to go a NetJet ISDN BRI card ($150? for two lines)
or X100P ($100?) per 1 line, or VoiceTronix OpenLine4 ($500?), OpenSwitch 6/12 ($800/$1500?)
for 4/6/12 analogue lines.

The openswitch cards can operate groups of the ports as FXS ports too.
