Re: [Soaplab-users] ACD outfile problem: how do you return a file? (soaplab2)

It looks like you should combine above two options into one. your Java
programs output seems not connected to the Soaplab service output. You
should have something similar to the following option.

# -dumpAudio <file> flag
outfile: dump_audio [
  qualifier: dumpAudio
  standard: "Y"
  default: "output.wav"
  information: "dump audio to this file (default: output.wav)"
  comment: defaults
#  comment: "display false"
  comment: "mimetype audio/x-wav"
  comment: bindata
  comment: "make_url yes"
]
