This is the phone that was the follow on to the 500
phone. This one has a 12 key Touch Tone dialing pad.
Inside it still has real bells. When you have a phone that's
conected to the line it's not a good idea to leave it off hood.
That 's why in the photo above the handset is holding down the hook
switch. This is the phone that's just ot the left of my computer
keyboard. Since there's no battery or wall wart needed to power
this phone, it works fine when there's a power outage. It seems
outages are getting more common as power poles are being replaced.
Just noticed that this phone is marked: Mf'd by Cortelco Corinth MS
so it's not a real Bell System phone.
I use this as my office everyday phone. The only downside is that
there is no redial function and it takes up a lot of desk space.
