I use the adsl portion only and dont use the POTS at all, both at home and at work. Firstly because I think telkom are a waste of money and i am a Vox telepreneur which means that I use a Vox phone (VoIP), they at least pay some money back to me for use of their product.
I have a 2mg line for ADSL
would be higher but Telkom cant give me a stable line
I only use the line to call Telkom on 0800375375 to report faults on a monthly basis
