| <p>This element will detect DTMF tones and emit messages.</p> |
| <p>The message is called <code class="classname">"dtmf-event"</code> and has |
| the following fields:</p> |
| <div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "> |
| <li class="listitem"><p> |
| gint <code class="classname">type</code> (0-1): |
| 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 |
| specfied by their number. This element can only take events as input. |
| Do not confuse with "method" which specified the output. |
| </p></li> |
| <li class="listitem"><p> |
| gint <code class="classname">number</code> (0-16): |
| The event number. |
| </p></li> |
| <li class="listitem"><p> |
| gint <code class="classname">method</code> (2): |
| This field will always been 2 (ie sound) from this element. |
