 Installation
 ------------
 
 For Debian testing or unstable there is an official public repository
 provided by AG Projects. Install the AG Projects debian software signing
 key:
 
 wget http://download.ag-projects.com/agp-debian-gpg.key apt-key add
 agp-debian-gpg.key
 
 Add these lines in etc/apt/sources.list
 
 # AG Projects software
 deb http://ag-projects.com/debian unstable main
 deb-src http://ag-projects.com/debian unstable main
 
 After that, run:
 
 apt-get update
 apt-get install callcontrol
 
 For non Debian installations, you must install the following dependencies:
 
 python-application (>= 1.2.8)
 python-twisted-core
 python-sqlobject
 
 Call Control software is available as a tar archive at:
 
 http://download.ag-projects.com/CallControl/
 
 Extract it using tar xzvf callcontrol-version.tar.gz and change directory to
 the newly created callcontrol directory.
 
 The source code is managed using darcs version control tool. The darcs
 repository can be fetched with:
 
 darcs get http://devel.ag-projects.com/repositories/callcontrol
 
 To obtain the incremental changes after the initial get:
 
 cd callcontrol
 darcs pull -a
 
 Install the software:
 
 cd callcontrol
 python setup.py install
 
 
 You may run the software from its own directory or install it in a directory
 anywhere in the system.
 
 
 Configuration
 -------------
 
 You must setup the following components:
 
 1. OpenSIPS configuration
 2. Call Control (this application)
 3. CDRTool rating engine
 
 
 1. OpenSIPS configuration
 
 loadmodule "mi_fifo.so"
 loadmodule "mi_datagram.so"
 loadmodule "sl.so"
 loadmodule "tm.so"
 loadmodule "dialog.so"
 loadmodule "call_control.so"
 
 modparam("call_control", "disable", 0)
 
 route {
 ...
     if ((method=="INVITE" && !has_totag())) {
        # you need to call this function at the first INVITE
         call_control();
         switch ($retcode) {
         case 2:
             # Call with no limit
         case 1:
             # Call with a limit under callcontrol management (either prepaid
             # or postpaid)
             break;
         case -1:
             # Not enough credit (prepaid call)
             xlog("L_INFO", "Call control: not enough credit for prepaid call\n");
             acc_rad_request("402");
             sl_send_reply("402", "Not enough credit");
             exit;
             break;
         case -2:
             # Locked by call in progress (prepaid call)
             xlog("L_INFO", "Call control: prepaid call locked by another call in progress\n");
             acc_rad_request("403");
             sl_send_reply("403", "Call locked by another call in progress");
             exit;
             break;
         case -3:
             # Duplicated CallID
             xlog("L_INFO", "Call control: duplicated CallID\n");
             acc_rad_request("400");
             sl_send_reply("400", "Duplicated CallID");
             exit;
             break;
         default:
             # Internal error (message parsing, communication, ...)
             xlog("L_INFO", "Call control: internal server error\n");
             acc_rad_request("500");
             sl_send_reply("500", "Internal server error");
             exit;
         }
     }
 ...
 }
 
 For more information see the documentation that comes with the OpenSIPS
 callcontrol module.
 
 
 2. Call Control configuration (this application)
 
 The application is searching for its configuration file config.ini in its current
 directory and in /etc/callcontrol/config.ini
 
 ; detect sessions that have media timeout without BYE
 timeout_detection=dialog
 
 [CDRTool]
 ; connection to cdrtool rating engine for MaxSessionTime() and DebitBalance()
 address = cdrtool.hostname:9024
 
 [RadiusDatabase]
 ; connection to Radius database if timeout_detection=radius, you must enable
 ; MediaProxy Radius accounting for this to work
 ; user = radius
 ; password = password
 ; host = db
 ; database = radius
 ; table = radacct%Y%m
 
 [OpenSIPS]
 ; connection to OpenSIPS call_control module
 ; socket_path = /run/opensips/socket
-; max_connections = 10
 
 A more detailed sample configuration file is available in config.ini.sample.
 
 
 3. CDRTool rating engine
 
 Please see the documentation of CDRTool project to setup the rating engine.
 
 
 Logging
 -------
 
 Call Control logs all activity to syslog. You may grep for call-control in
 syslog. The requests can be correlated by call-id with the syslog entries
 generated by CDRTool rating engine.
 
 
 Control commands
 ----------------
 
 Monitoring active sessions:
 
 /etc/init.d/callcontrol sessions
 
 Displaying information about an active session:
 
 /etc/init.d/callcontrol session id
 
 Terminating a session:
 
 /etc/init.d/callcontrol terminate id
