It does the G723.1 encoding in the DSP. The Quicknet xJack products do the
same thing enabling you to use that codec without violating the licencing
involved. The best way to get this working would be through the OpenH323
code. Some of the people on the openh323 mailing list are looking at a
driver for this device as well. A cross of the USB people and the openh323
people would be the best way to get this working quickly with input from
both sides of the fence. Then you could use this device with something
like gnomemeeting
