Yes the migration to VoIP has been underway for a few years, but due to Covid and other reasons it's been a very slow one.

I helped out a couple times in the switchroom moving cable pairs for the techs. It wasn't with a punch down tool, but a manual wire wrap tool! It's been many years since I've used one of those. Old technology is still here, for a little while at least. I still have a highly modified 1A2 system at home. Behind the living room couch is a 25 pair cable connected to a 66 block. One of several 'IDFs' in the house. Unlike the 5ESS I work with, the home system won't be decommissioned.
