Asterisk and voice conference

[SuperDuG]

I am unable to start voice conferencing. I was able to before the
upgrade to 0.63 and just found out about it earlier today as no one
had been apparently trying to use it.

I have provided what I thought was relevant information below. Ubuntu

There are known issues with Ubuntu 9.10.  Can you use 9.04?

Okay, so I'm a bonehead ... changed the bbb_extension.conf from XXXXX to XXXX

Now the error is::

[Feb 24 17:44:14] NOTICE[9587] chan_sip.c: Peer '3024' is now Reachable. (3ms / 2000ms)
[Feb 24 17:44:17] WARNING[9700] pbx.c: No application 'Konference' for extension (bbb-voip, 85432, 2)


as for downgrading, I would very much rather not.  I'm not opposed to 10.04 pre-release, but physically reverting to 9.04 isn't an option I'd like to explore right now

[Jeremy Thomerson]

To fix the "konference" error, you need to install our fork of AppKonference.  You can download the latest code at http://github.com/jthomerson/AsteriskAudioKonf but I think the version that is included with BBB 0.63 is tagged correctly at http://github.com/jthomerson/AsteriskAudioKonf/tarball/bbb_v0.63

Assuming you have GCC and company installed, you should be able to untar that file and cd into konference, run "make && make install" and be done (after restarting Asterisk).

That worked swimmingly ... and hints as to how I turn off the hold music? :-)

[Jeremy Thomerson]

I suspect it's as easy as changing the dial plan options where you find the "konference" application.  Reference for application option flags is here:
http://github.com/jthomerson/AsteriskAudioKonf/blob/master/konference/Dialplan.txt

Hi Doug,

If you remove the .ulaw files from

/var/lib/asterisk/moh/

it will remove the music on hold.

Regards,... Fred

Actually Jeremy's response explained it

in my bbb_extensions.conf Konference is called with the dialplan
argument of H ... which is set to have hold music until there are n+1
participants in the conference.

It's working exactly as designed!

Thanks for the help everyone!

Removing the MOH is a bad idea for where this may be integrated with other telephony systems.  But if all you're using the server for is BBB and you want absolutely no MOH, you can do that.  Removing the flag gives you more future flexibility.

Two ways to accomplish the same thing.

I like Jeremy's solution better :-).
