All,
I am in need of a H.323 Proxy, or reflector, to simplify the IP network
that is being developed for VTC. The problem I am trying to solve is
connecting separate networks together, using private links, so everyone
can dial each other over these dedicated links. The separate networks
have private links purchased usually due to special funding, or other
regulatory issues. Some of the networks connected are on different
ISP's, further complicating the layer 3 network routing.
In order to simplify and abstract the dial plan from each entity, I am
going to stand up a central gatekeeper that all entities can peer with.
This will be a "free trade zone" for all those who want to join "the
network". What I need now is the ability to "route" all the traffic
through a central location such that layer 3 routing is also simplified
across all entities. Asking each entity to create a custom route table
or add static routes for each customer is not scalable.
The inter organizational call volume will be small. It will rarely be
more than a handful of simultaneous calls at any given time.
I am currently experimenting with GNUGK and its proxy feature. I can
get the system to proxy calls when I register endpoints directly to the
GNUGK. However when I set up a neighbor GK and make a call the call
completes, but it is not proxied. I have tried with and without an
internal network config statement and even the Endpoint Function
registering as a Gateway and Endpoint with no luck.
The setup is below.
EP1 < -- > gk1 < -- > GNUGK < -- > gk2 < -- > EP2
I would like the GNUGK to proxy all calls from gk2 or any other gk that
it is peered with. Is this possible? If so, how? If GNUGK cannot do
this, is there a product that could? Config of GNUGK is below.
Thanks in advance!
