I wrote some notes on this but have yet to wiki it. example of an outbound socket connection where the call is answered, a variable is set then perhaps play one of the pre-installed files and hangup. ivrd
fs_ivrd comes with freeswitch. It being a small daemon just invokes the script defined in a variable and passes data from it via STDIN/OUT Since this is an outbound socket connections it needs to be defined in the dialplan. Ex: <extension name="outbound-socket"> <condition field="destination_number" expression="^55(522)$"> <action application="set" data="ivr_path=/usr/local/freeswitch/scripts/ivrd-demo.php"/> <action application="socket" data="127.0.0.1:8084 async full"/> </condition> </extension> The above dialplan sample would invoke ivr-demo.php when 55522 is called as long as fs_ivrd is running. To start fs_ivrd: /usr/local/freeswitch/bin/fs_ivrd -h 127.0.0.1 -p 8004 It takes 2 arguments -h for hostname and -p for port. PHP Code #!/usr/bin/php -q <?php // set a couple of things so we dont kill the system ob_implicit_flush(true); set_time_limit(30); // Open stdin so we can read the AGI data in $in = fopen("php://stdin", "r"); // Connect echo "connect\n\n"; // Answer echo "sendmsg\n"; echo "call-command: execute\n"; echo "execute-app-name: answer\n\n"; // Play a prompt echo "sendmsg\n"; echo "call-command: execute\n"; echo "execute-app-name: playback\n"; echo "execute-app-arg: /usr/local/freeswitch/sounds/en/us/callie/ivr/8000/ivr-welcome_to_freeswitch.wav\n\n"; // Wait sleep(5); // Hangup echo "sendmsg\n"; echo "call-command: hangup\n\n"; fclose($in); ?> ivrd will call this script for each call. All itdoes is answer the channel tell FreeSWITCH to play the “welcome to freeswitch” prompt. Since the script is now controlling all call flow I needed to add a wait or it would send the hangup immediately before the prompt was played. Some improvements possible but that's 1 way to do it. It would be possible to do the socket directly in PHP but fs_ivrd is a nice option too. -- W _______________________________________________ FreeSWITCH-users mailing list FreeSWITCH-users@lists.freeswitch.org http://lists.freeswitch.org/mailman/listinfo/freeswitch-users UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users http://www.freeswitch.org
