I'm a little confused by this non-sequitur. Why would your old
Touch-Tone phone care about the details of your back-end connection to
the PSTN (copper to the CO vs. VOIP)? How could it tell?

I got VOIP fromTime-Warner Cable more than four years ago and did not
have to change any of the phone instruments in the house. That
includes the early-1980s Bell Touch-Tone desk phone that we have in
the basement. Going to VOIP didn't change my internal wiring at all;
it only required connecting that internal loop to the cable modem.

I have a VoIP phone that has an RJ45 ethernet jack on the back, not a RJ11
phone jack. I also have some VoIP terminal adapters that have an RJ45 on
one side and an RJ11 on the other, for backward compatibility. That's
what your telco gave you.

Both have their advantages. You can do more interesting things with a
direct net connection, but Mickey Mouse phones only come with RJ11's.

R's,
John

That was an error on my part.
