<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):
