Closed GoogleCodeExporter closed 8 years ago

Hi,

I'm install BigBlueButton 0.71 on FreeBSD 8.1 amd64 according to:
http://code.google.com/p/bigbluebutton/wiki/InstallingBigBlueButton

And found one problem - when user joined to the conference (and listen
greeting), his do not appear in the Listeners window. At this time
red5 logs show java exeption:

==> stdout.log <==
[ERROR] [EslEventNotifier-1] org.freeswitch.esl.client.inbound.Client

I tested three different versions of the FreeSWITCH and found:

BBB 0.71 workfin only with one specific FreeSWITCH version:

ol/main/f/freeswitch/freeswitch_1.0.6-0ubuntu10-10-15-11-24PST.1~lucid.tar.gz

with freeswitch-1.0.6 - i have an error:

freeswitch-snapshot.tar.gz (12-Nov-2010 16:12 114M) - no any visible errors, 
but listeners window still empty.

Could you please check and confirm this ?

Also please see similar Issue# 639 
(http://code.google.com/p/bigbluebutton/issues/detail?id=639) for log files and 
other info.

Thanks a lot!

Hi Alex,

We have looked into this problem and found that the packages that the Ubuntu 
install uses are the same version as the .tar.gz you are using, all from 
October 10, 2010.

We have not tried out the latest builds of FreeSWITCH so we did not know that 
BigBlueButton wasn't working with them.  I noticed you did some pretty in depth 
testing and filed a bug with FreeSWITCH 
(http://jira.freeswitch.org/browse/ESL-52).  This is definably an event issue.  
I have attached my working configuration files but from inspecting what was 
posted in Issue 639 your addresses fairly ok, however see my notes below.

We have found that in bigbluebutton-sip.properties (in 
/usr/share/red5/webapps/sip/WEB-INF/) the sip.server.host had to be equal to 
the ip of the machine that is the SIP server, even if that IP is that of the 
current machine.  From our testing we found using 127.0.0.1 doesn't work. I did 
notice in your sip-diff.txt file you had used 127.0.0.1.

The other two files, bigbluebutton.properties 
(/usr/share/red5/webapps/bigbluebutton/WEB-INF/) and the event_socket.conf.xml 
(/opt/freeswitch/conf/autoload_configs/) should have matching IP addresses, be 
it 127.0.0.1 or an external IP address.  A few things I noticed here.  In your 
red5-webapps-bigbluebutton-diff.txt I noticed that you had changed your 
ami.host to "localhost", I'm not sure if it will resolve this or not, however 
this is for Asterisk.  The esl.host is for FreeSWITCH.

I couldn't find your event_socket.conf.xml, which is where the listening server 
is set for FreeSWITCH, so I'm not sure what you have there.  The 
bigbluebutton.properties and event_socket.conf.xml are event related.  
bigbluebutton-sip.properties is used to tell red5 where the server is (Asterisk 
or FreeSWITCH).

Hope this is helpful and you can get your setup working.  Let us know what your 
current status is.

Scott

Hi Scott,

Thanks for update!
I tried your proposed files but the error appears again.
After that i registered bug for FreeSWITCH: 
http://jira.freeswitch.org/browse/ESL-52
Now this bug fixed. BigBlueButton works fine with FreeSWITCH again!

Tested on: FreeBSD 8.1 amd64, tomcat-6.0.29, red5-0.9.1 and FreeSWITCH GIT from 
23.11.2010.

P.S. 127.0.0.1 for SIP/ESL also work fine:
