fixed the borken (written by ANOTHER LANGUAGE developer?) Session collectInput example

Session collectInput example

function tenDigitCollector( session, type, data, arg ) {
  if ( type == "dtmf" ) {
    arg.digits += data.digit;
    return arg.digits.length >= 10;
  }
  
  return true;
}


if ( session.ready() ) {
  var dataStore = {
    digits: ""
  };
  session.answer();
  session.streamFile( "sounds/typeSomeDigits.wav" );
  session.collectInput( tenDigitCollector, dataStore, 3000, 0);
  console_log( "info", "Got " + dataStore.digits + "\n" );
  session.streamFile( "sounds/thanksBye.wav" );
  session.hangup();
}
