Bridging a Polycom into the AG

[Ti Leggett]

While lying down resting, I was thinking that it probably wouldn't be
too hard to bridge a polycom unit into the AG so that a) Remote polycom
users could participate in an AG meeting without an AG and b) AG users
could participate in a h323 meeting.

On a related note, after wiring the uM2 up to be AG-ified and getting
the linux PIG nodes working smoother, I've found out several things:

- MatchMakers aren't needed. In order to use unbalanced audio with the
Genter, wire tip or left channel to positive on the phoenix connector
and tie ground to negative and ground on the pheonix connector. Viola!
- It looks like the alsa sound drivers are a valid free alternative to
the 4Front drivers, at least on PIG nodes. I just installed the alsa
drivers on personal-ag which has an i810 chipset and it's full duplex
and seems to work quite nicely. We need to find an alternative to the
4Front drivers because a) Their should be an open source alternative re:
latest discussion on Groove and b) the es1370 chipset is no longer being
made and c) most computers are coming with onboard sound which by and
far is the i810 or Via chipsets
- The linux PIG drm doesn't by default transmit video. The effect this
has is that you can't get your own video feed locally until you check
the transmit from the menu. Oddly though your video is being fed because
remote users see it fine. I guess that's becuase the vrm is
transmitting.
- A linux port of the genter software would come in *very* handy on the
uM2 AG node.
