Ok, so first up, you will need this or something similar in your extensions.conf:
[podcast]
exten => s,1,Answer()
exten => s,2,Background(podcast)
exten => s,3,goto(2)
; === Security
exten => 1,1,Set(url=http://SecurityWireWeekly.blogspot.com/atom.xml)
exten => 1,2,Agi(mytest)
exten => 1,3,Set(url=http://www.codesermon.org/portals/15/podcast.xml)
exten => 1,4,Agi(mytest)
exten => 1,5,Goto(s,2)
; === VoIP
exten => 2,1,Set(url=http://vonradio.pulver.com/podcasts/audiorss.xml)
exten => 2,2,Agi(mytest)
exten => 2,3,Goto(s,2)
; === Comedy
exten => 3,1,Set(url=http://extrafancy.net/blog/wp-rss2.php)
exten => 3,2,Agi(mytest)
exten => 3,3,Set(url=http://podcast.dailystupid.com/blueg/index.xml)
exten => 3,4,Agi(mytest)
exten => 3,5,Set(url=http://feeds.feedburner.com/TripleParadoxPodcast)
exten => 3,6,Agi(mytest)
exten => 3,7,Goto(s,2)
And you will also need the AGI file:
#!/usr/local/bin/php -q
<?
require "phpagi.php";
$agi = new AGI();
function read() {
global $in, $debug, $stdlog;
$input = str_replace("\n", "", fgets($in, 4096));
if ($debug) fputs($stdlog, "read: $input\n");
return $input;
}
$url2 = $agi->get_var("url");
require_once('/var/lib/asterisk/agi-bin/magpierss/rss_fetch.inc');
echo "VERBOSE \"[" . $url2 . "]\"\n";
$rss = fetch_rss($url2);
$x=0;
foreach ($rss->items as $item) {
if ($x < 1) {
$x++;
$dat = $item['atom_content'];
$dat2= $item['guid'];
$dat3= $item['enclosure'][0]['url'];
$title = $item['title'];
echo "VERBOSE \"URL: ".$dat3."\"\n";
if (strlen($dat3) > 0){
$dom3 = $dat3;
} else if (strpos($dat2,"mp3") > 0) {
$dom3 = $dat2;
} else {
$dom = stristr($dat, '<a href="');
$dom2 = stristr($dom, '"');
if (strlen($dom2) > 0) {
if (strpos($dom2,'"',1) - 1 > 0) {
$dom3 = substr($dom2, 1, strpos($dom2, '"', 1) - 1);
} else {
$x--;
}
} else {
$x--;
}
}
}
}
if (strpos($title,"VONradio")>-1) {
$title="VON Radio";
}
echo "SET VARIABLE mytest \"" . $dom3 . "\"\n";
echo "EXEC MP3Player " . $dom3 . "\n";
?>
You will also need to install magpie rss into the /var/lib/asterisk/agi-bin/magpierss/ directory.

333Suggestions to get this to work
1. Put context brackets around podcast when installing it into your extensions.conf file
2. Make sure that you have an audio file called podcast in your sounds directory
3. Replace the "1" in line 1 of the mytest.php file with a # sign
4. I had to remove the "/local" part of the pathname for php - read #!/usr/bin/php -q
So now with these changes, why does this still not work. Can you suggest a few strategic debug statements to put into the mytest.php file?
