<a name="gst-plugins-good-plugins-rtpdtmfmux.description"></a><h2>Description</h2>
<p>The RTP "DTMF" Muxer muxes multiple RTP streams into a valid RTP
stream. It does exactly what its parent (<span class="type">rtpmux</span>) does, except
that it prevent buffers coming over a regular sink_%<code class="literal">u</code> pad from going through
for the duration of buffers that came in a priority_sink_%<code class="literal">u</code> pad.</p>
<p>This is especially useful if a discontinuous source like dtmfsrc or
rtpdtmfsrc are connected to the priority sink pads. This way, the generated
DTMF signal can replace the recorded audio while the tone is being sent.</p>
