  Responding to OPTIONS packet with 404 because Asterisk not looking for "s" extension.
  
  The get_destination() function was not using the "s" extension when the
  request URI did not specify an extension.  This is a regression caused
  when the URI parsing code was extracted into parse_uri().
  
  Made get_destination() substitute the "s" extension when the parsed URI
  results in an empty string.
