Carsten: The main issue is really the playout length supported by the conference room echo cancellation systems. The remote side echo can have as much as > 200 msec rtt and i have not seen systems supporting tis well except dedicated ones built for that purpose. Might be related to the DSP cost which may go up with rtt you want to support, not quite sure about the algo's Ideally nowadays this should be taken care of by CPU within meetecho itself if thats really whats used as the channel to connect room with remote participant. Not sure if meetecho itself does echo cancellation.
