Subject: [Openh323gk-developer] A IP-IP H323 Gateway based on GnuGK
2.2beta4
Dear developers,
As so far, GnuGK can act as H323GK as well as a H323 Proxy, but not
a
Gateway.
After some coding works with GnuGK, I accomplished a IP-IP Gateway,
which could route calls between differend H323 zones, and I am glad to
share
it with you all, to contrib my works to the GnuGK project.
The idea of this ip-ip gateway is like this:
Zone 1 Zone 2
GK1 GK2
/ \ / \
/ \ / \
EP1 IP-IP Gateway EP2
Here GK 1 knows nothing about GK2 nor EP2, nor a ip route is
required.
IP-IP Gateway will registered with both GK1 and GK2 as a Gateway, with
some
prefixes declared.
Now if EP1 make a call that has a destination matches these prefixes,
call will be routed to the IP-IP Gateway, and IP-IP Gateway would
initiates
a ARQ in Zone 2 to GK2 and conduct the call to proper termination.
In fact, this IP-IP Gateway can route calls between more than 2 zone,
just a matter of configuration file works.
