Re: [Freeswitch-users] PHP ESL & Event Socket Outbound

11 Jul 2013

      Hi,

This works for me with PHP and outbound socket.

Dialplan: *** sends connection to IP A.B.C.D port 8084

<extension name="test">
    <condition field="destination_number" expression="^\*\*\*$">
        <action application="socket" data="A.B.C.D:8084"/>
    </condition>
</extension>

xinetd picks up the connection and sends to the script. xinetd config is:

*service unlisted
{
         user                = whoever
         disable             = no
         type                = UNLISTED
         socket_type         = stream
         protocol            = tcp
         wait                = no
         server              = /home/test/test.php
         port                = 8084
     server_args         = HOST
}

*
The php script picks it up from there

#!/usr/bin/php
<?php
require_once('ESL.php');

$esl = new ESLconnection(0);

$ans= $esl->execute('answer');

$subscribe = $esl->sendRecv('myevents');
$subscribe = $esl->sendRecv('linger'); # Without this the channel closes
before we receive the events
$res = $esl->execute('sleep', '1000');

$context = $esl->getInfo()->getHeader('Caller-Context');
$curr_user = $esl->getInfo()->getHeader('variable_sip_from_user');
$curr_host = $esl->getInfo()->getHeader('variable_sip_from_host');

///etc etc.

Hope that helps

Mike

Hello,
I am trying to create PHP application that will be receiving information
about each call from freeswitch and send commands to control freeswitch.
I found an example at https://wiki.freeswitch.org/wiki/PHP_ESL#ivrd  BUT
unfortunately they do not explain how I can retrieve information from
freeswitch (so I can do the routing in PHP).
I guess I should use PHP ESL but the documentation is pretty bad so if
someone has some working example, I'd appreciate it.
I tried to read from stdin this way:
*#!/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 data in
$in = fopen("php://stdin", "r");
// Connect
echo "connect\n\n";
// READ DATA
$text = fgets($in);
file_put_contents('/usr/local/freeswitch/scripts/socketlog.txt' ,$text,
FILE_APPEND);
// Answer
echo "sendmsg\n";
echo "call-command: execute\n";
echo "execute-app-name: answer\n\n";
// Play a prompt
echo "sendmsg\n";
echo "call-command: execute\n";
echo "execute-app-name: playback\n";
echo "execute-app-arg:
/usr/local/freeswitch/sounds/en/us/callie/ivr/8000/ivr-welcome_to_freeswitch.wav\n\n";
// Wait
sleep(5);
// Hangup
echo "sendmsg\n";
echo "call-command: hangup\n\n";
fclose($in);
?>*
*Unfortunately, everything I get as a result in my log file is:*
*Event-Name: CHANNEL_DATA*
