I do more with less hardware without any problems.  In one of our
offices I have a single P4 2.8Ghz with 1GB Ram and two SATA RAID 1
drives.  This machine currently serves about 35 sip phones (about 25
actively used), has a TE410P with one PRI, a TDM22 handling 2 backup
POTS lines on the FXO's and fax machines on the FXS's, and connects to
6 other offices via IAX that transcode to GSM.  It also acts as a DNS
resolver, the FTP server for the Polycom SIP phones, and runs NTP.  At
one point I had it running FOP, which is fairly resource intensive.
It could very easily handle much more.  Top shows the CPU is between
92% (12 active channels) and 99.8% (2 active channels) idle, and
memory usage at about 470MB total, 290MB active.

All this is to say that you have plenty of hardware for your current
needs and considerable growth.
