I never succeeded with this module.
My install:
- the latest drupal bbb dev,, the latest bbb 0.8 beta 4
- added api-0.8.bbb.inc as per http://drupal.org/node/1310654
- modified voiceBridge as per http://drupal.org/node/968470

When I start a meeting, bbb disconnects after 1 minute. I get these errors in the logs that fire at the exact time I press "Moderate":
- "invalidPassword: You must supply the moderator password for this call." if I did not filled in a password
- "notFound: We could not find a meeting with that meeting ID" if I filled in a password

Any hep would be much appreciated
