TopTV was bitten by ICASA this year (2012) when it shut down the broadcaster’s plans to launch porn channels in South Africa. In its explanation for denying TopTV’s application, ICASA said: “TopTV’s failure to take ICASA’s public consultation process seriously fatally damaged its application”.
I don't seen how you could call that fraud, and I don't think the exchange can "answer" calls as you put it. If there is no telephone at the other end of the line, the line will just ring continuously, or be diverted to whatever the current divert is set to. I suppose this could earn Telkom some interconnect revenue if the calling party is off-network, though it easily cancels out with Telkom's costs on the line. Also, why doesn't she just cancel her line, or port her number to Neotel? Telkom doesn't have a duty to provide a service. It has no legal obligation.
It's obvious that reducing IPC connect charges are going very little to reduce call rates. Let's see how much teeth ICASA has to regulate the actual call prices that cell phone providers are charging. Less into the shareholders pockets and sponsorships of major events and more whre it actually matters. My daugghter's rubber snake has stronger teeth than ICASA.
