Ok, so I've got BBB setup, I'm setting the voicebridge and webvoice settings; however, when i dial in to freeswitch it tells me that i'm the only one in the conference, the audio can't be heard through the computer bbb client, and it doesn't show a new user in the bbb client nor does it bind the audio to my existing user in the bbb conference. I've followed the instructions in the FAQ, but it didn't resolve the issue. Below I am listing my create.jsp, bbb_api.jsp,netstat and bbb-conf --check settings.

Jeff, use /opt/freeswitch/bin/fs_cli to watch freeswitch

1) Join BBB normally, then do > conference list

2) Then Dial into freeswitch and do > conference list

This will show if you both users are in same confernence or not......

Your dialplan when dialing into freeswitch, should prompt you, or
transfer you to the correct bbb conference

paste the results of test and we can help you.
