Subject: Re: [Openh323gk-users] Proxy Mode to traverse firewalls
There has been some movement to add H.460.18/19 to GnuGk. PacPhone now
supports H.460.18/19 and is totally Free. It also supports GnuGk NAT method
so you can NAT traverse if you are registered to either GnuGk or
Tandberg/Polycom/Radvision but more importantly it contains P2Pnat Media
which allow the H.460.18/19 calls to avoid the need to proxy media which
makes it a lot more scalable. This will be a part of GnuGk v2.2.8 and will
also work with GnuGk NAT method. If you have a windows box (not vista) then
there is a GnuGk version with the technology on the PacPhone website. I will
be merging P2Pnat Media to the GnuGk CVS head after the v2.2.7 release.
Technical Info on P2Pnat Media can be found here. It is currently working
its way though the ITU at the moment.

Hello Andrew,
I'm managing a VC network of almost 70 public high schools, all with
legacy Polycom Viewstations, and with every imaginable firewall, connecting
from all over the state via Internet. I'm doing almost exactly what you are
asking about (If you look at the mailing list posting before yours' you'll
also see some of what I'm not succeeding at) in the testing phase. I think I
may already have a working configuration for what you want. Drop me an email
and we can exchange phone #.
GnuGK has its own firewall traversal, and it works very well in the most
common situations (at least in my experience). It's related to the
H.460.18/19 approach that the V2IU as well as the Tandberg and Radvision
solutions support, but it's not the same. (But you may want to look up some
of Simon Horne's posts on this list to see the status of H.460 in H323plus
and GnuGK development). It also proxies (which is important) and neighbors
well (which helps in a situation like yours and mine, with one central phone
number database).
The problem with those commercial solutions for us is the licensing
sucks: Polycom lets you use any number of clients up to the bandwidth of the
unit, but doesn't give you a software client for old non-H.460 endpoints.
Radvision gives you a software client but charges too much per user (for our
situation - we occasionally have 50+ schools in a call).
Hope I can be of some help,
--Paul
