星号agi呼叫失败然后接下来

Question

我试图让我的php-agi脚本拨打下一个命令,如果第一个命令忙或者无论如何都失败了.我现在设置它的方式不仅仅是工作,它只是返回繁忙然后死亡,或者如果它工作,它将发送两个拨号命令.这是我得到的:

$agi->exec('DIAL',"SIP/".$target."@".$ip.",30,g");
$agi->exec('DIAL',"SIP/".$target."@".$ip2.",30,g");

对此有任何帮助,非常感谢,提前谢谢!

Answer 1

当你打电话给Dial()星号时,设置一个名为DIALSTATUS的通道变量.您可以从AGI中阅读.

来自CLI的"核心显示应用程序拨号"的输出:

${DIALSTATUS}: This is the status of the call
CHANUNAVAIL
CONGESTION
NOANSWER
BUSY
ANSWER
CANCEL
DONTCALL: For the Privacy and Screening Modes. Will be set if the
called party chooses to send the calling party to the 'Go Away' script.
TORTURE: For the Privacy and Screening Modes. Will be set if the
called party chooses to send the calling party to the 'torture' script.
INVALIDARGS

防爆.

    $agi->exec('DIAL',"SIP/".$target."@".$ip.",30,g");
    $dialstatus = $agi->get_variable('DIALSTATUS');
    if ( $dialstatus != 'ANSWERED' ) {
      $agi->exec('DIAL',"SIP/".$target."@".$ip2.",30,g");
    }

所以逻辑只是在没有应答第一个呼叫的情况下进行呼叫.
