Hi,

I'm trying to achieve the following:

Incoming call for user A (97), user A make a blind transfer to user B's
phone (96).
User B's phone rings and since there is no one to take the call, it
returns the call to User A with an AGI script.

The dialplan looks like this:

[local]
....

exten => 96,1,Dial(SIP/user4,10,tr)
exten => 96,2,AGI(transfer.php)

exten => 97,1,NoOp("MARKE1------------")
exten => 97,2,DIAL(SIP/user1,20,tr)
exten => 97,3,NoOp("MARKE2-------------")
exten => 97,4,BUSY()

transfer.php:

#! /usr/bin/php -q

<?php
$i=0;
ob_implicit_flush(true);
set_time_limit(6);
error_reporting(0);
$stdin=fopen("php://stdin","r");
while(!feof($stdin)){
$temp = fgets($stdin);
$temp = str_replace("\n","",$temp);
$s = explode(":",$temp);
if( $s[0]=="agi_dnid"){
// $s[1] contains the number that has forwarded the call
$stdout=fopen("php://stdout","w");
fwrite($stdout,"NOOP(dummy)");
fwrite($stdout,"SET CONTEXT local");
fwrite($stdout,"SET EXTENSION $s[1]");
fwrite($stdout,"SET PRIORITY 1");
fclose($stdout);
}
}
fclose($stdin);
?>

And here is the output on the cli:

-- Launched AGI Script /var/lib/asterisk/agi-bin/transfer.php

Why doesn't the script jump to priority 1 in extension 97?
Is there really an "Invalid or unknown command", I couldn't find one?

Thanks for your help,

Stefan
