Patrick, Openmeetings does not currently use software Acoustic Echo Cancelling.
If the computers being used do not support hardware AEC, I recommend that people use headsets or speakerphones like Alexei suggested. I have successfully used the ClearOne Chat 60. I have also learned that some computers support hardware AEC if enabled in the drivers (sadly mine does not).

But I'm using openmeeting from France with somebody in North America and I've very strange echo problems: When I speak, 2 or 3 seconds later I'm listening myself in a strong echo. Checking "reduce echo" in adobe flash player popup do not change anything. Using some other webconferencing solution like vidyo do not show the problem. Do you have any idea about this strange problem ?
