Sounds like someone is looking for a job at Net1 :). From a statistical point of view though, I fail to understand how the difference in number of subscribers should result in one network owing the other in interconnection fees if the cost of an internetwork call is the same between all the networks. The fewer Net1 subscribers making many calls each to Econet subscribers should on average be cancelled by the many Econet subscribers who at some point will make a call to a Net1 subscriber. Some subscribers receive more calls than they make (in total minutes) and others make more calls than they receive. Is there anything that would drive subscribers who make more calls than they receive to be concentrated on the smaller network thereby creating an imbalance in what should be a statistically random distribution?
