## Description

The RTP "DTMF" Muxer muxes multiple RTP streams into a valid RTP stream. It does exactly what its parent (rtpmux) does, except that it prevent buffers coming over a regular sink_%u pad from going through for the duration of buffers that came in a priority_sink_%u pad.

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.
