First off, I apologize if this has been sent multiple times, the mailing
list won't cooperate with me... Hopefully that is resolved now.

I'm attempting to replicate the behavior of an Asterisk conferencing
system and I need a feature that, I'm surprised to say, doesn't seem to
be supported (easily) in FreeSwitch.

I've setup my dialplan so that when a specific extension is hit, it
calls out to some javascript which acts like an IVR to handle the
prompts and conferencing setup. (Similar to this:
http://wiki.freeswitch.org/wiki/Examples_confcall_js but with my own
improvements.) Anyway, the conferences are stored permanently in a
database table, but I need them disabled until the conference owner
dials in and enables his conference. If other users have entered the
conference prior to the owner, they should hear music-on-hold until the
leader enters. (The purpose of this is to prevent abuse of conferences
that are, basically, always available.)

This is easy in Asterisk because you can pop someone into MeetMe with
different flags. So, in my IVR, I prompt for the "conference number"
(known to all) and then the "password" (known only to the owner/leader).
If the proper password is entered, that user is sent to conference XYZ
with the leader flag set. If no password is entered, the user goes to
conference XYZ, without the leader flag. If anyone enters before the
leader, they're told by MeetMe that "the conference will begin when the
leader arrives" and MeetMe provides MOH until that time.

Help! This is an absolute deal-breaker for my install... How can I do
this in FreeSwitch?
Thanks...

Jason,
There are many ways to accomplish this using FreeSWITCH. All of
which will require you to do a little bit of coding in js, lua or some
other language.

1. Park all callers into a fifo.. (see mod_fifo)
2. When leader auths in your script then you uuid_transfer them all
into the conference.

You could also do this via esl using perl, lua, python, php or ruby.

That should accomplish the same ending result.

the easiest way would be the new feature I added to 13442

in the conference profile add

<param name="conference-flags" value="wait-mod"/>

to your <profile>

and in your dialplan

<action application="set" data="conference_member_flags=moderator"/>
<action application="conference" data="1234@wideband"/>

or

<action application="conference" data="1234@wideband+flags{moderator}"/>


Don't forget the wishlist and donate button on the main site....

Michael,

Pardon me for hopping on this thread, but can you explain more about this new feature? I've been wanting something like this to apply different behaviors for different conference members. Can this be used to provide a 'moderator' with different behaviors bound to DTMF keys than regular callers?

Anthony - unbelievable! Thank you so much for implementing that! I kept
going through the possibilities of using a FIFO, putting the javascript in a
polling loop, or having everyone enter the conference muted and manually
playing MOH. This feature absolutely makes my code a snap... Yes, I will
remember the wish-list and I will update the wiki (probably tomorrow
though).

Stephen: This new feature doesn't provide the ability you're referring
to... It gives me the ability to make normal users "wait" on a moderator to
open the conference.

However, the capability you're asking for already exists in FreeSwitch by
choosing different "profiles" for your conferences. Within the
mod_conference config file you can create different profiles which use
different "caller controls" a.k.a. "in-conference dtmf features". So,
create one profile for your normal users and another identical profile
(except for the caller controls) for your moderators/admins.

When you put them into the conference, you can select your profile like so:
<action application="conference" data="1234@profile_for_users"/>
<action application="conference" data="1234@profile_for_moderators"/>

I hope that's all correct - again, I'm new.

Anthony, I will try this out first thing tomorrow!

This opens the door to what you ask but to add moderator specific dtmf controls is another patch that would require specifics and most likely a bounty or contract to complete.

Thanks j3flight, I have used that method, but the profiles seem to be for conferences not users. So I give a conference a profile, and everybody in the conference shares the profile settings. If I'm wrong, let me know, otherwise I'll stop hijacking this thread.

Nope, it seems you are absolutley correct. I had setup my conferences this
way, but hadn't experimented yet. I tried putting two users into the same
conference using different profiles, but they both had the same caller
controls. Bummer.

I believe we can get around this though, assuming I can call javascript from
the caller controls. Currently, I am using a trick in my conference IVR
where I scan the UUIDs in a conference looking for an IsModerator variable
that I set when they were dropped in. If a user has that variable set to 1,
they are a moderator.

I could use that same trick from the caller controls to determine whether
that user has moderator permissions and can act (or not act) on their button
press. I'll give it a shot at some point and post back.

It would be an improvement to move the caller controls to the member so it works
the way you expect but it will have to wait for the right time and motivation level.

From there it would also be possible to make up some new caller controls that were moderator inspired like (mute all besides moderator) stuff like that.

I don't want to get too fancy because the idea behind the conference is to keep it clean.
We do have a caller control that just sends an event so an external application can catch it and use esl to do the desired action such as, dial 4, get the event on the socket decide it means mute all and then send the correct series of api calls to mute each member.

Wiki Tax paid...
That was my first contribution to the freeswitch wiki!
MC, you're welcome to have a look over it and see if i made things clear
enough. Feel free to edit.

And the wiki tax if you feel comfortable adding this to the wiki. If not let
me know and I'll add it.

I could not get this working on current trunk. Can you post your configuration on conference module and the dialplan example?

Thanks,
