Comment # 2 on bug 11905 from 
No statistics are generated because all RTP packets have the Marker bit set.
According to RFC 3551:
For applications which send either no packets or occasional comfort-
   noise packets during silence, the first packet of a talkspurt, that
   is, the first packet after a silence period during which packets have
   not been transmitted contiguously, SHOULD be distinguished by setting
   the marker bit in the RTP data header to one.  The marker bit in all
   other packets is zero.  The beginning of a talkspurt MAY be used to
   adjust the playout delay to reflect changing network delays.
   Applications without silence suppression MUST set the marker bit to
   zero.
