DTMF不被PHP Agi接受

Question

I am trying to grab the DTMF from user, if its equal to zero then transfer call to an extension else hangup. I have written the following, but it directly plays invalid entry and hangs up my call. Would appreciate help over this matter.

$wheretorec = $agi->exec("AGI","googletts.agi,\"To speak to an operator press zero.\",en"); 
$whereto = $agi->get_data($wheretorec, 10000, 1);
$dtmf = $whereto['result'];

if (is_numeric($dtmf ['0'])) 
{
$agi->exec("AGI","googletts.agi,\"Your call is now being transferred\",en");
$agi->exec('transfer',"SIP/123@12.345.678.901:5080");   
$agi->hangup();
} 
else 
{
$agi->exec("AGI","googletts.agi,\"Invalid entry. Please try again later.\",en");
$agi->hangup(); 
}
}

Answer 1

Have be like this

$dtmf = $whereto['result'];

if ($dtmf=="0")

Please read corefully phpagi docs and examples

Answer 2

$dtmfTemp = $agi->get_data("File_name_you_want_to_play", 6000, 1);
$dtmf = $dtmfTemp['result'];
if($dtmf=="0"){
//Do your stuff
}
else{
//Do your other stuff
}

Answer 3

This is the code that has worked for me.. if I try anything instead of 'silence/1' or 'beep' then it gives me an error message, invalid entry!

$press1 = $agi->get_data('silence/1',50000, 1);
$press1dtmf = $press1['result'];
