Should be plenty if not an overkill. One of our setups: 20 phones, 8
outgoing/incoming SIP trunks, MeetMe conferencing with ztdummy and no
Zap hardware. IVR/voice mail/MOH/Recordings/etc. Runs on a single
PIII-600, 256 MB RAM. CentOS 4.4 with a stock 2.6.9-42 kernel.
Asterisk 1.2.5, in production for 1.5+ years. CPU usage about 2% per
call. Quite reliable (hence not upgraded). This is a g711 only setup
with no transcoding.
