A native_rtp bridge is used for more than direct media. It is also
used for local native bridging, that is, when you have two RTP capable
channels in a bridge and Asterisk does not require the media to flow
through its core. The bridge then just performs a packet to packet
swap between the two RTP capable channels.

Note that on verbosity 4, Asterisk will tell you if the bridge is
locally or remotely bridging the two channels.
