I just tested on our production system - ISDN passive card with CAPI on
a PII/400. A call from ISDN (alaw) to a GS (G.729a) used on average 5%
system, 2% user time with peaks to 25% system, 10% user. So even this
comparatively weak system should be able to handle up to four calls (all
probably depending on codec conversion), more when I finally get that
active ISDN card that's been on backorder for weeks now...

(instead of a bigger phone system, just install an IRC server - works
wonders for us ;-))
