  The chan_dahdi faxdetect option only works for the first FAX call.
  
  The chan_dahdi faxdetect option only works for the first call.  After that
  the option no longer works.  The struct dahdi_pvt.callprogress member is
  the encoded user config setting for the callprogress and faxdetect config
  options.  Changing this value alters the configuration for all following
  calls until the chan_dahdi.conf file is reloaded.
  
  * Fixed the chan_dahdi ast_channel_setoption callback to not change the
  users faxdetect config setting except for the current call.
  
  * Fixed the chan_dahdi ast_channel_queryoption callback to read the active
  DSP setting of the faxdetect option.
  
  * Made actually disable the active faxdetect DSP setting for the current
  call on the analog port.  my_handle_dtmfup() is used for normal analog
  ports.  dahdi_handle_dtmfup() is the legacy code and is no longer used
  unless in a radio mode.
