Sailboats are ancient, but they're still a reliable way to get across
a body of water. Some people pay a very large amount of money for a
sailboat, and then they race other sailboats. Bikes are still the most
efficient way to move a human. Algebra and calculus are are old. I
still use them everyday. Actually, I bike to work too.

Ummm, I've never had my physical phone lines vulnerable to the latest
SIP credential guessing game. I don't have to license a codec just to
terminate a phone call. I can think of several more advantages. But as
I mentioned in my original post, I have a lot of physical telco
circuits because they cost less when you do a lot of call volume. VoIP
is nice inside the border where it can't be attacked by the script
kiddies, and where bandwidth is free.

Wire has a fixed cost. Telephone billing incurs costs in direct
proportion to the amount of calling. If you pay an extra 1 cent per
minute for voip, times 10,000,000 minutes a year, well, I'll happily
pocket the difference.

It must have been pretty reliable then :) I've had to patch for SIP
vulnerabilities several times in two years.
