[asterisk-users] Problem sending a DTMF remotely. Please need help!!

Hello,

I need to be able to send a DTMF to an existing channel remotely. So I made
a php script to do such with the Manager command PlayDTMF. I need it for
example to start a transfer.

isb177*CLI> features show
Builtin Feature           Default Current

(none)

Call parking
------------
Parking extension   :      70
Parking context     :      parkedcalls
Parked call extensions:      71-78


My script is:

#!/usr/bin/php -q
<?php
error_reporting (E_ALL);
set_time_limit(60);
ob_implicit_flush(false);
$ip_asterisk = "127.0.0.1";
$user_asterisk = "admin";
$pass_asterisk = "forward";
$canal = "SIP/1000-0a292360"; //hardcodeado

$oSocket = fsockopen($ip_asterisk, 5038, $errnum, $errdesc) or
die("Connection to host failed");
    fputs($oSocket, "Action: login\r\n");
    fputs($oSocket, "Username: $user_asterisk\r\n");
    fputs($oSocket, "Secret: $pass_asterisk\r\n\r\n");
    fputs($oSocket, "Action: PlayDTMF\r\n");
    fputs($oSocket, "Channel: $canal\r\n");
    fputs($oSocket, "Digit: #\r\n\r\n");
    usleep(500000);
    fputs($oSocket, "Action: PlayDTMF\r\n");
    fputs($oSocket, "Channel: $canal\r\n");
    fputs($oSocket, "Digit: 8\r\n\r\n");
    usleep(500000);
    fputs($oSocket, "Action: Logoff\r\n\r\n");

   $loaded = "";
    while (!feof($oSocket)){
        $buffer = fgets($oSocket, 4096);
        $loaded .= $buffer;    }
    $vec = explode("\n", $loaded);
    $len = count($vec);
    print_r($vec);
?>


The script output is:

Array
(
    [0] => Asterisk Call Manager/1.1
    [1] => Response: Success
    [2] => Message: Authentication accepted
    [3] =>
    [4] => Response: Success
    [5] => Message: DTMF successfully queued
    [6] =>
    [7] => Response: Success
    [8] => Message: DTMF successfully queued
    [9] =>
    [10] => Response: Goodbye
    [11] => Message: Thanks for all the fish.
    [12] =>
    [13] =>
)


When I run the script I can hear the two digit (only the audio) but nothing
happens, the Transfer menu doesnt start. The Cli shows:

BUT, if I press #8 in the softphone, I can hear the two digit and
inmediately the Transfer menu begins playing 'pbx-transfer.gsm'. And the
Cli
output in this case is:

Pablo, I did not answer in the first place because I am not completely
sure, but just guessing, PlayDTMF just generates DTMF sounds, inband,
and not info/rfc2833 messages, that's probably why you hear the tones
but nothing happens. Just my two cents, perhaps it throws some light.
