Yes, a B2BUA handles the media stream, so you are 100% correct. I forgot that
part of the SIP terminology :-)

I would like to add that even though Asterisk from a SIP proxy standpoint is
a bit limited, it's a very clever B2BUA for connections to the PSTN as well
as other VOIP protocols. If someone adds IPv6 connectivity, we'll be a really
wonderful IPv4 to IPv6 VoIP gateway as well.
