title: Asterisk Phpagi DTMF
body: <p>I have been searching around but I can't seem to find the answer. I want to see if what I want to do is possible:</p>
  
  <p>I want to playback music on hold to my caller when my phpagi script is executed. Is there anyway I can grab any DTMF that is being pressed during the musiconhold? I want the music to play continuously....</p>
  
  <p>Any kind of insight I can get on this is greatly appreciated.</p>
