a gatekeeper is only needed for H.323 (not SIP) but I assume we are going
to use H.323. A note: most gk's do not traverse NAT well unless the gk is
on the physical firewall. see caveat below.

dunno about ipcop.

GNUgk is the gatekeeper that I use(d). v2.0.4 (just released) has
NAT/H.323 proxy built in. http://www.gnugk.org/gkdoc/RELEASE-NOTES gnugk
is not the easiest to compile, it requires the newest versions of PWLib
and the OpenH323 from the openh323.org site. Old versions of pwlib and
openh323 need to be removed. The compile time on the p4 should not be too
bad but on < 1Ghz can take an hour or longer.
