This is a basic configuration for a Conference Bridge Application using ARI and Node.js.

This application requires Node.js 0.10.X.

$git clone https://github.com/semidy/node-confbridge-js.git
$npm install

$npm install pg

Once you have created and configured your database, you will want to modify the dbConnection in the config.json to point to your database. For example:

postgres://user:secret@localhost/user

Run the following commands to create and/or reset all default tables, indexes, user profile, group profile, and bridge profile settings:

$cd scripts
$node defaultdatabase.js

After you have created and configured your specific database and run the defaultdatabase.js script, you are now able to setup your own specific user, group, and bridge profiles, within the scripts folder, that are to be added to the database.

Run the following commands to add a new user to the database:

$node adduser.js

Run the following commands to add a new group to the database:

$node addgroup.js

Run the following commands to add a new bridge to the database:

$node addbridge.js

Modify the ariConnection in the config.json to point to your Asterisk Instance.

Add the following to your dialplan to test the default connection:

exten => 8888,1,NoOp()
        same => n,Stasis(confbridge)
        same => n,Hangup()

Also you can add the name of your user_type and group_type in the stasis application if you have changed it from default. For example:

exten => 9999,1,NoOp()
        same => n,Stasis(confbridge, usertypename, grouptypename)
        same => n,Hangup()

Start the application:

$node app.js
