The strange one is when your own number pops on the caller ID.

My cell phone number shows up quite often on my land line CID. If I'm running around and think of
something I want to remember later, I'll often call my home phone and leave a message as a reminder.
Works well.
I am talking about the POTS number showing up on the POTS caller ID.

What is POTS?

Plain Old Telephone Service

Well, I just reckon I am pretty low tech.

I still have 2 rotary dial phones connected. That is low tech.
The one in my garage still has the original Telco label in the dial
face with my phone number on it. That is the best phone in the house
for reliability.

I remember when you had to pay for DTMF dialing capability. I always thought that was funny, because you know they had to go into the PBX turn it off for folks that didn't pay the extra charge. Then you had the phones you could buy that had a switch for rotary/DTMF. You could avoid the charge from local Bell for DTMF, but still switch the phone and use DTMF if needed.

Did you know you can rotary dial without using the dialer? For example, if you want to dial a "2" you just depress and release the hookswitch buttons in the cradle twice, very quickly. That's all the rotary dialer does... it interrupts loop current the same number of times as the number dialed. 0=10.

I am aware of all of that, in fact in the Bell System the only thing
paying got you was a guaranteed DMTF originating register. If you
tried a few times you still would get one in a random manner.
On the system I had when I moved to PG county, it was so rare that I
didn't get one I would forget and think my phone broke.
Later when they went to ESS, they had to add extra hardware to deal
with the rotary dialers. After deregulation and a lawsuit or two the
RBOCs dropped that fee.
Down here when we had Clem and Bubba's phone company, the central
office in Ft Myers was a #5 and they still had a stepper office in
Naples. It wasn't until the late 80s when Sprint bought it that they
moved to ESS. There were 2 floors of a big building in both offices
full of clicking stuff, then one day it was just the frames along the
wall on one floor and a guy sitting at a computer console. The other
floor was empty.
They did have the government packet sniffer in Ft Myers but we were
not supposed to know about that.


Packet sniffer?

===

Packet Sniffer is a generic term for the ability to surreptitiously
monitor digital communications which are broken into packets for
transmission. That includes virtuall all internet traffic.

There aer a number of licit and illicit operations which do that.
