I use voice because it's there, but 90% of my calls are to toll free numbers, and I probably make around 5 or so calls per month at most. I never answer the phone, unless I know it's someone who arranged with me ahead of time. If I had no voice service I wouldn't care.
I took out my ADSL service through MWEB who at that time offered a discounted ADSL/DSTV combo. The offer was removed later, but the discounts for both remain.
Because I work from home, I use the line for both data and voice with 2 pcs (soon to be three) sharing the line.
What I pay is:
MWeb - R379 per month 3Gb cap and 384kb
Telkom - 144.74 per month line rental plus voice call charges.
I understand entirely why telkom have given a "voice" line as part of your ADSL package. They need a means to be able to track your circuit. You need the copper last mile and this was the easiest way to do it. Infrastructure (managemnet billing record details) was already in place
If you rent a dedicated line from telkom you still pay for the copper portion as a seperate line item in the total bill
