Managed conferencing solution using 
Asterisk, Web-MeetMe and a database-driven scheduler
by Dan Austin <dan_austin@fitawi.com>
================================================================

** Background
	It has been suggested that conferencing in general and 
MeetMe specifically represent the killer app to drive Asterisk
integrations.  While MeetMe does provide a solid foundation for
audio conferencing, there is a need for a management interface
that allows system administrators, conference administrators,
and system users to schedule, monitor and manage conferences.

** Security concerns
        It is strongly recommended that register_globals be
turned off.  The Web-MeetMe UI no longer needs this feature
turned on, and if it is turned on the system may be vulnerable
to XSS.

** Using Web-MeetMe with Asterisk 1.6 or newer
	Starting with Asterisk 1.6, the logic to enforce
conference start times, end times and resource limits have
been moved into app_meetme.  This means that this package
no longer needs app_cbmysql, however an updated verion
is included for sites that already use WMM and cannot
convert to using RealTime.  It is highly recommended that
new installations use RealTime and not app_cbmysql.

** The tools

Web-MeetMe
	Web-MeetMe is a collection of PHP pages that leverage
the database for scheduling and the Asterisk Manager interface
to monitor and control active conferences.

	The scheduler currently supports these features:
		+ Conference number conflict avoidance
		+ Recurring conferences 
		  * Daily, weekly or bi-weekly 
		+ Enforces a user password if a admin password 
		  is set
		+ Seperate views for past, current and future
		  conferences
		+ Editing future conferences
		  * Includes a series of conferences
		+ Deleting past conferences
		+ CDR-like view of past conferences
		  * Includes a link to conference recordings
		+ One click features to-
		  * Extend an active conference (time)
		  * Kick out all participants
		  * Out-call to include participants 
		+ Optional early join features
		  * fuzzystart allows a caller to enter a
		    room early (in seconds, set in cbmysql.conf)
		  * earlyalert notifies a call that their 
		    conference has not yet started, if they
		    enter a valid conference number and the
		    conference is scheduled to start soon.
		    (in seconds, set in cbmysql.conf)

** Installation
* Dependencies
	-  Asterisk 1.6 or later
		!! Version 1.6.2.7 is the first suitable version
		!! Version 1.8.0 is recommended for full functionality
		!! res_odbc
		!! app_meetme configured to use RealTime
		!! cdr_adaptive_odbc is recommended for CDR functionality
	-  Database with ODBC driver
	-  PHP 4.3 or later
		!! Reports depend on mod_gd and GD-2.0.28
		!! or later
		!! PEAR::DB (php-pear)

* Tweak meetme.conf
	The default meetme.conf from Asterisk 1.6.2 or later has
the basics in place.  One exception is that logmembercount should
be set to 'no', as that feature of Realtime MeetMe conference is
not used by WMM.

* Configure ODBC
	Configure /etc/odbc.ini and add a section similar to this:

[MySQL-Asterisk]
Description     = ODBC for MySQL
Driver          = MySQL
Server          = 127.0.0.1
Database        = meetme
Port            = 3306
Socket          = /tmp/mysql.sock
Option          =
Stmt            =
Trace           = yes
TraceFile       = /tmp/odbc.log


	Configure /etc/asterisk/res_odbc.conf and add a section similar
to this:

[meetme]
dsn => MySQL-Asterisk
username => <db-username>
password => <db-password>
pre-connect => yes

	Add the following line to /etc/asterisk/extconfig.conf:

meetme => odbc,meetme,booking

	For CDR logs configure /etc/asterisk/cdr_adaptive_odbc.conf:

[wmm]
connection=meetme	;Note that this matches res_odbc.conf
table=cdr

	 In /etc/asterisk/cdr.conf confirm that endbeforehexten is set to 'no'

* Setup the database
	Create a table called booking in your database.  The
table is described in ./cbmysql/db-tables-v7.txt

	You can upgrade your database from an earlier install
by using this command:

mysql < ./cbmysql/upgrade-db.txt

	There is also a use the rollback-db.txt file to
revert the database to be compatible with WMM 3.X if you
need to downgrade.

	If you will be using a SQL database to store user 
accounts instead of using an LDAP service, you can use this 
command to setup the initial administrator account to logon to 
WMM:
mysql < cbmysql/db-admin-user-create.txt


* Install Web-MeetMe
	Download the latest Web-MeetMe tgz file from
http://www.sf.net/projects/web-meetme and extract it to your webservers
document root.

	Modify the ../web-meetme/lib/defines.php to match you
database settings.

	Copy ../web-meetme/phpagi/phpagi.example.conf to 
/etc/asterisk and modify it to match the settings in your
manager.conf

********************************************************* 
You must have an account in /etc/asterisk/manager.conf
similar to this:

[MeetMe]
secret = {pick-a-password}
read = call
write = command,originate

********************************************************* 


	If you intend to use the authentication functions,
it is strongly recommended that you use SSL and force all
conenctions to the Web-MeetMe pages to use HTTPS.

* LDAP or Active Directory integration
	Edit ./lib/defines and set the AUTH_TYPE to adLDAP.
Set the ADMIN_GROUP to appropriate list, the default is
"Domain Admins", but you might not want the network folks
controlling your telephony systems.  Optionally you can
chanege the browser session timeout.

	Edit ./lib/adLDAP and replace all instances of
"yourdomain" and "yourserver" with the values for your
network.

* Usage
	If all of the steps have been followed, you should be
able to open your browser, connect to the Web-MeetMe page and
schedule a conference.  A new conference start time defaults
to the time it is scheduled, so modify it if needed.  Any
required fields that are left blank will be auto-generated.
Note the conference room number and password.

	Dial the number you have assigned for conferencing, and
try the conference you have just added.  If the time and password
are correct, you will be joined to the conference.

	You can now use the Web-Meetme monitor function to manage
your conference.
