Cost savings
Back in the dim and distance past, I was IT support for a company that provided services for Oil Companies with offices around the world.
Most of them we quite small with less than a dozen or so people. We tended to use small Phillips PBXs for them, wonderful things.
One place in Africa had HUGE phone bill, even more than we were expecting, so I came up with a plan...
Everyone would have a PIN code that would report back the use of each code AND set the guard hut up with local calls only.
I never did get the reporting system to work properly, it was too flaky to be reliable, BUT just saying that the call billing would be logged to your pin and restricting the calls worked, and the costs dropped to about a 1/3 of what they were, and the first month savings paid for the ticket and time to do the work...
Turns out because the guards previously had unrestricted calls, they would supplement their meagre income by selling international calls.
