  ...within SIP, native bridging has two subcategories.  One, typically referred
  to as "SIP native bridging" is used when reINVITEs are enabled.  The endpoints
  send their media directly to one another.  The other subcategory is called
  "Packet 2 Packet" or "P2P" bridging.  If reINVITEs are not enabled, but there
  are also no features that require the Asterisk core to be in the voice path,
  then the bridging will be done at the RTP layer of Asterisk.
