<td>The application uses this field to specify which of the two methods
specified in RFC 2833 to use. The value should be 0 for tones and 1 for
named events. Tones are specified by their frequencies and events are specied
by their number. This element can only take events as input. Do not confuse
with "method" which specified the output.
