我解决不了一个问题，脚本的目的是识别上下文号。
下面是星号拨号计划扩展.conf

exten => 1234,1,Answer()
same => n,Set(NUM2CALL=Hello, your number is eight)
same => n,NOOP(${NUM2CALL})
same => n,AGI(test.php,${NUM2CALL})

运行test.php的文件

# !/usr/bin/php -q

<?php
require '/var/lib/asterisk/agi-bin/phpagi/phpagi.php';
$agi = new AGI();

//DB connect
$mysqli = new mysqli('127.0.0.1', 'root', 'testdatabase', 'asterisk');

if (mysqli_connect_errno())
{
    printf("Connect failed: %s\n", mysqli_connect_error());

    exit();
}
//End

$query  = "SELECT text, number FROM recognation_2";
$result = $mysqli->query($query);

while ($row = $result->fetch_object())
{
    if(strpos($argv[1], $row->text) !== FALSE)
    {
        echo $row->number;
    }
}

?>
