[Freeswitch-users] PHP ESL & Event Socket Outbound

[Mike Raistrick]

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
