There are several companies that supply my company with parts and fabrications that if you call them you get a live operator not a computer who then connects you with who you want to talk to - they are getting fewer and further between but back in the 90's it was still very common to have that be the case.
Back in the 90's a lot of Army bases were still using consoles that had just recently replaced switchboards - example is the article I am attaching - Joint Base Elmendorf-Richardson
They used a wire switchboard until 1991 and then switched to a manual console which was still in use during the V1/V2.2 timeline period - the switch to computers didnt happen till later.
