Dear All,<br>         I have set my socket mode as full. I have used ESL.pm to develop an IVR. I encounter the situation that I need play some music file while executing some external application. So, I used executeAsync method  to play the music file. But the executeAsync application didn&#39;t work.<br>
<br>       What is the problem? Please help me....<br><br>Thanks,<br>Velusamy.<br>
