So can one jack be set up the old fashioned way with the phone company

Most of my phones are touch-tone (even that term is dated) but I still
have a rotary dial phone. I don't use it often enough to bother
replacing it, and I rarely dial out on that phone. It takes nothing
special, account-wise.

The jacks are super-easy to install. Your local borg or Radio Shack
will have everything you need.
