There were none four months ago. Zero. Only D-Link and LinkSys
were really in the market back then, at a sub $150 CDN mark.
Voip-info.org had a much shorter list, then. ;)
I spent over 10 _hours_ double checking, verifying, you name it. Much
more than I would have chosen to spend on the issue. It is very, very
good to see that things have changed in a few short months.
After all, it was very sickening to have to pay extra money, because both
d-link and linksys where in bed with the devil.

As well as D-link, at least at the time. :/

Not really, you can't. NAT with SIP is a royal pain in the rear end.
Aside from that, a normal PC eats up extra power and cost far more than
one of these little linksys boxes.
Manpower is another consideration as well.
By doing what you're suggesting, the cost skyrockets to several hundreds
of dollars per installation, from a mere $120 or $130 per. What a company
needs is a complete, finished, drop and go solution here.
Playing around with old pcs.. hacking things to work as you want.. it's
too expensive to handle things in that fashion. A $50 used PC may seem
like a great deal.. but when include the manpower to get that working...
Suddenly it's a horrible idea.

I'm referring to quality of service, not quality of service. ;) I
probably should use another term. What I mean is, I'm not referring to
marking packets, but I _am_ referring to making sure that SIP traffic gets
out the door first.
This is what these nice little routers do, that a firewall can't do, if
you run anything at all on that firewall.
