[Freeswitch-users] PHP ESL Problem

[Ron McLeod]

Would someone please take a look at this simple PHP event socket script and
tell me what I am doing wrong - or tell me that this could be a bug
elsewhere?  Any help would be appreciated.

When I run the script without the call to execute(), everything seems fine.
When I include the call to execute(), the calls to getType() return CUSTOM
for a while, then later start to return the correct name.

#!/usr/bin/php
<?php
require_once 'ESL.php';
$endPoint = 'sofia/internal/695%192.168.100.132';

$eventSocket = New ESLconnection('192.168.100.132', '8021', 'ClueCon');
$event = $eventSocket->events('plain', 'ALL');

// call endpoint, get uuid
$event = $eventSocket->api('originate', $endPoint . ' &park');
$serializedEvent = explode("\n", $event->serialize());
foreach ($serializedEvent as $eventLine) {
    list($dummy, $uuid) = explode('+OK ', $eventLine);
    if ($uuid) { break; }
}

// play announcement to endpoint
$event = $eventSocket->execute('playback', '/opt/ann/user-busy.wav', $uuid);

// monitor events
while (TRUE) {
    echo "getType: " . $event->getType() . "\n";
    $serializedEvent = explode("\n", $event->serialize());
    foreach ($serializedEvent as $eventLine) {
        list($header, $value) = explode(': ', $eventLine);
        if ($header == "Event-Name")   { printf($eventLine . "\n"); }
        if ($header == "Content-Type") { printf($eventLine . "\n"); }
    }

	printf("\n");
    $event = $eventSocket->recvEvent();
}?>
