Back in the good old days, even before Lazar was working where ever; large military posts/bases had their own telephone exchange. There 3 different
types of telephone lines available for usage. Class A, Class B, and Class C.
A Class A line would allow a person to call anywhere. These phones had a sticker on them telling you the phone call will be monitored for official
business.
A Class B line would allow you to call only other numbers within the exchange which means only on the post/base.
A Class C line was a dedicated line that was only site to site. The phone was usually red or white in color.
Fast forward to today. Everything is monitored and filtered.
