[asterisk-dev] Native Bridging: terminology

[Klaus Darilion]

Hi!

What is the exact meaning of "native bridging"? For example I know with 
DAHDI it means direct bridging on the hardware. But what about from one 
DAHDI interface card to another DAHDI card? Are there some optimizations 
that the audio stays within the kernel module or is it always send via 
Asterisk's core?

Or in case of a SIP-to-SIP call with canreinvite=no. Will there be some 
optimizations that audio stays within the rtp module or will it be sent 
via Asterisk's core? If there are such optimizations - is this called 
direct bridging or is direct bridging the RTP exchange between clients 
directly using canreinvite=yes (which I would not call direct bridging 
but "offload" or "bypass")? Or is this the "external native bridge"?

thanks
