The basics
ICASA's future numbering plans include a whole bunch of things - 10 digit dialling, prefix definitions, etc. The prefixes will be:
| 01x-05x | Geographical areas |
| 06x | Reserved |
| 07x | Mobile cellular and "future non-geographic services" |
| 08x | Mobile cellular, paging, inbound call services and future nongeographic services |
| 09 | To be replaced by 00 for international dialling |
Hidden nugget
M-Web has been allocated the 0877 prefix for its VoIP customers. Telkom will not terminate calls on (i.e. won't route to) 0877. International telcos will.
This means you can call an M-Web customer from overseas, but not from next-door.
Perhaps ICASA should determine whether being granted a portion of the limited numberspace should come with the cost of being forced to terminate on other licensees portions/prefixes (as a licence condition)? This is not directly analogous with IPv4 routing, as the only licensing effective is the RIRs selling IP space to whomever wants it (e.g. ARIN's fee schedule).
