Hi,
we organized a BBB-conference with people from 7 different south American countries. We sent invitation links to all 7 other participants. Since on our side as conference moderators we were already 4 people, we uses loudspeakers and a microphone. To prevent sound interference we always deactivated our microphone when we were not speaking ourselves and asked to do the same from the other participants. Nevertheless there were many problems with sound. Some countries could be hear very clearly, some couldn`t hear in part of the meetings, others could hear us very well, but we couldn´t understand them very well (often some words were cut out). We presented just two PDFs in the conference, 4 participants had their webcams activated.
How we an avoid this problems next time. The internet connection of our server is not optimal (we have only 10 Mbit/sec upstream/downstream) for the BBB-Server (we use bbb 0.9.0-beta on Ubuntu 14.04.1 LTS (64-bit), it´s a VM with memory: 7985 MB) and some of the countries have maybe bad internet connections as well.
Would it help trying without using the webcams? Is the reason for the sound problems more the internet connection of our BBB-Server or the internet connection on the side of the participants from the other countries? Or is it caused by routing between the countries? Or is there a problem with the configuration of audio in the other countries?
We really appreciate some suggestions how we could find out the source of the problems and prepare next time better.
Thanks and Regards
