How can i mute/unmute/kick joined to conference call

[Alex Bondarenko]

Hello all,

Please help with subject. My installation quite simple, rails
application with adhearsion app in it. Have enabled_rails and drb in
config so rails and ad can talk. Flow is client call asterisk,
asterisk talk to adhearsion and adhearsion join client to one of the
conferences by simple @call.join(pin).

Question is how i can mute/unmute/kick already joined user from my
rails app? How i can get access to joined client in adhearsion? I
tried call = Adhearsion.active_calls.find(unique_ident) but seems like
just bunch of data,
can't call much methods on it. What is the solution here?

Thank you for help!

You are right.  At the moment Adhearsion does not have awareness in Adhearsion::Call objects that recognize the state of the call (ie. "on a conference"), much less helper methods to directly manipulate them.  However, what you are trying to do is still possible.  It will depend on which Asterisk conferencing module you are using.  For the sake of argument, I will assume you are using MeetMe.

You will need to construct a new AMI message to perform an action on the channel in question.  The Adhearsion::Call objects do give you a handle on the channel unique ID, but keep in mind that this list is limited to those calls which actively have a connection to Adhearsion AGI (which may or may not be the case, depending on how your calls got into the conference).  To get what you want, you would do something like:

@manager = Adhearsion::VoIP::Asterisk.manager_interface

@manager.send_action 'MeetmeMute', :Meetme => room_number, :Usernum => ???

To be honest, I'm not exactly sure how to get the Usernum since I don't use Meetme.  But you can read more about the AMI commands that are available here:

https://wiki.asterisk.org/wiki/display/AST/AMI+Actions

Don't forget to rescue exceptions from send_action, in case of a ManagerInterfaceError.

Hey BAK!

Thank you for your response! You was right, AMI is what i was need to
look into.

Problem solved by config.asterisk.enable_ami in startup.rb and using
it from rails app via drb, like:
AdhearsionRemote.send_action 'MeetmeMute', :Meetme => "8081", :Usernum
=> "2"

where AdhearsionRemote defined as:

AdhearsionRemote = DRbObject.new_with_uri "druby://localhost:9050"

in initializers/.

I also check standalone.rb file in adhearsion's examples.
But basically it was your post who point me in correct direction, so i
really appreciate that!

One more question though, can't find action in AMI for kick user from
conference?
Is there any? or what is correct way to do that if not AMI?

There is an AMI command 'meetme kick', though documentation is (as ever) sparse. It takes an ID that you can find from 'meetme list'.

Hey Ben,

Can you please point me to doc where it described?
meetme kick it's meetmeadmin command which don't available in ami
afaik.

At least i don't see it in ami commands list
http://www.voip-info.org/wiki/view/Asterisk+manager+API.

And i just tried meetme kick like this:
AdhearsionRemote.send_action 'meetme kick 8081 1'

which return error for me.

Am i doing something wrong?

As I say, the documentation is virtually non-existant. The best I could find was Web-MeetMe (http://sourceforge.net/projects/web-meetme/), conf_actions.php#28 which reads:

if (($action=="mute") || ($action=="unmute") || ($action=="kick") ){

$res = $as->Command("meetme $action $confno $user_id");

sleep(1);

}

I don't use MeetMe, so I'm afraid I can't expand on that.

Ben Langfeld

There are a couple of good resources:

https://wiki.asterisk.org/wiki/display/AST/AMI+Actions

I do not see a direct AMI action to kick a user, but using AMI you can also execute any CLI command.  Here's some documentation on a "kick" CLI command:

http://www.voip-info.org/wiki/view/Asterisk+cmd+MeetMe

Or, on the Asterisk console, type:

"meetme help"

Worst case, go to the Asterisk sources directly (yeah, bad answer, I know).

Ben, BAK,

Thank you for your responses. You both were right.
I wasn't aware about possibility to run CLI commands via AMI.
But then i saw this http://www.voip-info.org/wiki/index.php?page=Asterisk+Manager+API+Action+Command

and then figured out correct way to do that:

AdhearsionRemote.send_action "Command", :command => 'meetme kick 6 1'

Thank you guys!
