Tariff 2

One company approached us as they kept receiving their telephone bill with thousands of pounds of calls made to pornographic international dialled numbers. They were an international company and didn’t want to blanket ban all international dialled calls, but they also didn’t want the cost of these calls.
 
They installed LUMBERJACK without warning their staff, and within a couple of hours, it was clear who was making the calls as they set-up real-time screens to alert them to when somebody called these numbers. The guilty party were asked quietly to refrain from calling these numbers and the embarassment was sufficient that they were not called again. The cost of the system was covered within a few days of installation.
