I have enabled the AEC feature in the client in r1446971.
There might be some new options to check in the enhancedOptions.
Basic guide is here:
http://www.adobe.com/devnet/flashplayer/articles/acoustic-echo-cancellation.html
Some of them could be made configurable in the config.xml, but I had no
time yet to look into it more detailed.

@Maxim If the issue with the file permission and the mxmlc executable is
fixed, IMHO you can close OPENMEETINGS-529
@George You are welcome to test with your users
@Timur Theoretically we can use SPEEX codec. I think SPEEX is a bit better
for AEC and bandwidth usage. However my issue was the last time I used it
our recordings do no more work cause FFMPEG had very poor SPEEX support.
But I guess for VoIP integration SPEEX would be even more handy. Would it
help you if there is SPEEX in use?
