</span><ins>+Simple translation for AGI based scripts.
+
+* TODO:
+ + transform class.ivr.php to phpagi names so that scripts are not aware they're no more under *.
+ + add bindings to more functions ( record session, get variable, dial, ...).
+ + config file for event_listener ESL connection and other stuff...
+ + refactor check_hangup to already read data, and not reading and discarding stuff like that, it's awfull...
+
+* Files:
+ + class.ivr.php:
+ - simple bindings for IVR functions.
+
+ + processhandler.php:
+ - included by event_listener.php, ease the creation of always running daemons launched by cron, to be sure there's only
+ one instance running at the same time.
+
+ + event_listener.php:
+ - listen via event_socket ( inbound mode ) to CHANNEL_HANGUP_COMPLETE events, checking if variable_pid2kill is present, and
+ if so, will send a SIGHUP to that pid ( AGI behaviour ).
+
+* Usage example:
+ + launch event_listener.php via cron on the box running the scripts ( be sure that you edited the socket connection part ).
+ + launch fs_ivrd on that same box ( ./fs_ivrd -h host -p port ).
+ + write an extension to be handled by your scripts ( be carefull of the full path to the script ):
+ <condition field="destination_number" expression="^sockettest$">
+ <action application="log" data="WARNING ${caller_id_number}:${destination_number} EVENTSOCKET_TEST"/>
+ <action application="set" data="ivr_path=/usr/local/src/freeswitch/contrib/gled/php/test.php"/>
+ <action application="socket" data="127.0.0.1:9099 full"/>
+ <action application="hangup"/>
+ </condition>
+ + be sure the test.php is executable ( chmod +755 test.php ).
+ + call that extention ;)
