[Asterisk-Users] Outband call from php script

[Alejandro Vargas]

In  http://nerdvittles.com/index.php?p=63 I've found a simple script
for doing this.

file callme.php

<?php
// (c) Copyright Ward Mundy, 2005. All rights reserved.
// This script will only work with Asterisk at Home ver. 1.3 or higher
// Syntax: http://asterisk.dyndns.org/callme.php?number=sip/bv/4045551212
// where asterisk.dyndns.org is the fully-qualified domain name of
your Asterisk server
// and 4045551212 is the number to be called immediately to provide dialtone

// This script will not work without adding [callout] context to
extensions_custom.conf. See below.
// Change 24681234 below to a very secure PIN number that the user
will be prompted for when call is made.

// [callout]
// exten => s,1,Authenticate(24681234)
// exten => s,2,DISA(no-password|from-internal)

// For additional documentation, visit Nerd Vittles blog at
// http://mundy.org/blog/index.php?p=63

// No changes should be made below this line
// For BroadVoice, dial strings should look like this: SIP/bv/14045551212
// To call a local extension with SIP, use the syntax: SIP/200 where
200 is the extension number
// MAKE ALL EXISTING ACCOUNTS SECURE BEFORE OPENING ASTERISK WEB
SERVER TO BIG, BAD INTERNET!!!
$number=strtolower($_REQUEST['number']);
$pos=strpos ($number,"local");
if ($number == null) :
 exit() ;
endif ;
if ($pos===false) :
$errno=0 ;
$errstr=0 ;
$fp = fsockopen ("localhost", 5038, &$errno, &$errstr, 20);
 if (!$fp) {
  echo "$errstr ($errno)<br>\n";
} else {
 fputs ($fp, "Action: login\r\n");
 fputs ($fp, "Username: phpagi\r\n");
 fputs ($fp, "Secret: phpagi\r\n");
 fputs ($fp, "Events: off\r\n\r\n");
sleep(1) ;
 fputs ($fp, "Action: Originate\r\n");
 fputs ($fp, "Channel: $number\r\n");
 fputs ($fp, "Context: callout\r\n");
 fputs ($fp, "Extension: s\r\n");
 fputs ($fp, "Priority: 1\r\n\r\n");
sleep(2) ;
 fclose ($fp);
 }
echo "Extension $number should be ringing now." ;
else :
 exit() ;
endif ;
?>

Add this to extensions.conf (or extensions_custom.conf if you are
using asteriskathome)
[dialtone]
exten => s,1,DISA(1234,from-internal)
exten => s,2,Hangup

where "1234" is a pin that must be entered
