I don't think a node can do this (H323) by default. I often have to use
H323 with webcasting and its just an integration issue.
If the customer has money, I use a Polycom Viewstation and use the VCR
ports to give video and audio in and out. That then goes into my sound and
video mixers and gets mixed down like any other source. A copy of the
webcast video then gets fed down to the other end.
The audio is a little trickier (without a Gentner), so I use the mix minus
technique on my mixer and gate the audio manually if I get stuck. Not great
but works.
We get multi-party H323 by using a commercial conference bridge. (I think
its the Radvision MCU)
If the customer doesn't have money (common outside the commercial arena), I
use the D-Link i2eye DVC-1000. it costs around NZ$800, so thats US$400 or
less. It doesn't allow me to feed it video, so place the unit at the front
of your AG room. Feed the video from your DLink into one of the video
inputs on the AG so that it pops up on the screen. Feed the audio into your
gentner and feed audio out from the gentner to the D-link (into the mic
connex).
And it should all work.
There is a VERY nice H323 card thats used in flyaway codecs for broadcast
(like the Scotty or talking head) but they will only sell to me in OEM lots
of 10, which works out at NZ$30K. You could install that into your node and
it would integrate really well. But I don't have a spare $30K <sigh>.
