I suspect that some combination of Telephony service, ICS, and ICF /
Windows Firewall is causing your trouble. If you can boot up a Linux
partition, I think you will find that gnugk runs fine. If it is not practical
for you to use Linux, BSD, etc. for your gateway, try to determine
what is not working in Windows:
You can easily test with the firewall disabled. Before doing so, of course,
make sure that you have all security updates installed, and disable
file and print sharing, and any other services that you don't want to
be accessed from outside. You can use "netstat -o -a" to see
what ports are open and what processes are listening on them.
If it works with the firewall off, it may just be the audio packets being
blocked. Try setting RTPPortRange to a few ports and opening those
UDP ports in the firewall.
If not, try a test with ICS and Telephony also disabled. When you turn
off ICS, the settings for your LAN interface may be reset. If so, manually
configure it for a 192.168.0.1 static IP. Then, after a reboot, Telephony
should not be running. If it is, stop it manually. Of course, in this test
setup, the other hosts on your LAN won't be able to access the Internet,
but your IP phone and your friend's endpoint should be able to register
with gnugk, and I believe that calls should be possible. If not, try adding
NetworkInterfaces=192.168.0.1/24,61.93.xx.xx/xx. If it still doesn't
work, you should run Ethereal on both interfaces to see why the proxy
isn't doing its job.
If gnugk runs ok when ICS, etc. is disabled, you have several options:
1. Use an inexpensive hardware router for NAT. Choose one that allows
you to forward required port ranges to gnugk.
2. Use a third-party NAT software, instead of ICS.
3. If your other hosts only need to access the Internet for Web and email
(and VoIP), you could use an application proxy instead of NAT.
4. Find out precisely what fails when ICS is enabled. There may be a
workaround in the configuration, or with a patch to the source.

I don't have a Planet IP phone, but do use some of their gateways.
Those have a bug (feature?) that causes the ringback to continue to
play, until audio packets are received from the destination, when fast
start is not used.
