Hi,
This is the exact thing what I want to do at my organization too... So, thx
for asking this question.
Now, I have a firewall with a ALG for H.323 calls. Enabling that at the
firewall and using gnugk in -rr mode (H.245 Routed) makes it possible for
me to call remote end, and FYI I have only one GK inside the network.
If anyone has any better solution please post it here!!
Regards,
Vineet Menon
