VoIP... still issues
The vans will go for voip so data is the main stream
VoIP is all well and good, but you still need some sort of end point identifier.
If the VoIP numbers were only capable of dialing numbers on the same VANS, then it'd be fine, as the numbers would be under the VANS control. That wouldn't be very useful for the general public though. It could be for intra/inter office phone calls though within a multi-site company.
If the VoIP numbers could cross between VANS, then it would be much more useful, but in order for one provider's VoIP customer to call another's, there needs to be a common, agreed upon, numbering/routing convention. That on it's own would be a pain to manage, and agree on, and would fall under ICASA as it becomes industry regulation.
If the VoIP numbers want to be able to phone conventional numbers, you can have a gateway system similar to Skype's SkypeOut, but that only works to make calls. You can't receive calls from conventional numbers. I say conventional numbers because it covers both landline and cell phone. Landline penetration may not be much, but cellphone is huge. And not being able to call, or be called from, cell phones would be a major issue in this country.
In order for that to happen, the numbers need to fit into the current phone number system. Admittedly this is exactly why there was the migration to 10 digit dialing, but it'd still be a hell of a lot of management overhead on a regulator that is already doing a crap job. It'd just become a royal (maybe should be re-branded presidential?) mess... and would again require interconnection regulation/management etc.
I think we'd be better off with getting a decent regulator that can do their current job properly first. Then we can look at throwing a few more competitors in the mix. I still don't think that the full 50 to 100 would be a good idea. Maybe just the biggest 5, or have them bid for 5 licenses, and allow them to form partnerships prior to the bidding so that a group can together bid for one license. That could allow a number of smaller effective operators who are servicing local communities to join together to form one (hopefully) effective larger scale operator, without unnecessary buyouts and the like.
