I Think they are slightly worried about SMME Provisioning
Coz there is no CDMA "Switchboard" so to speak, unless you run a Normal PABX on CDMA "Premicells" (Not sure if they exist)
Who in their right mind would run a wireless PABX anyways? I find the idea some what suspect.
With Enterprise its different, they just pull Fibre into your place and give you a SIP Trunk or ISDN PRI.
I consider my Company to be a Medium Enterprise. and I am having a Meeting with the Key Accounts Holder next week.
Perhaps your Account wouldn't warrant them running fibre... they COULD phone and say, sorry there is nothing on offer for you at the moment, but lets face it, you WOULD bitch and moan and demand to speak to a manager. so my guess is they just dnt bother.
And if you phone the right number to BEGIN with, (Consumer, Enterprise, SMME) they don't have to transfer you around.
perhaps i'm lucky... but i was never lucky with Telkom.
