Unsurprisingly to most, I'm the guy who played one of the VoIP packets
(I'm in the blue Clearly IP shirt).
After his talk at LCA, I was discussing the way to handle VoIP, and I
mentioned that the way I do most VoIP client connections is via a
tunnel. This allows me to put a proper queue on the tunnel ITSELF, and
just hope that the actual outgoing link of the customer isn't
This seems to work reasonably well, and customers usually end up with
good audio (as well as bypassing all the NAT nightmares).
I'm hoping that Dave comes back next year to LCA (and for those that
missed the announcement, it's in Canberra), and can do some more talks
next year 8)
