title: How to handle DTMF on outcall using call files in asterisk?
body: <p>I'm making an outdial using call files in asterisk and application needs some DTMF input but DTMF not working for all mobile phones, It is not accepting digits from Nokia - 1100 and nokia 6030 where DTMF works if i make an incoming callfrom the same phone but on out dial using DTMF log i can see following messsage on asterisk CLI:</p>
  
  <ul>
  <li>DTMF Begin '1' received on Dahdi-32</li>
  <li>DTMF Begin ignored '1' on Dahdi-32</li>
  </ul>
  
  <p>If someone knows the solution for this please let me know.</p>
  
  <p>It works if i set overlapdial=no but in this case it doesn't make two simultaneous outdial on two different numbers.</p>
