Key facts
| Who they are | A hosted PBX provider describing its product as a switchboard for small and medium-sized companies, run from Ferndale in Randburg |
| Pricing — published in full | The first extension is R79 excluding VAT and includes your first phone number free. Additional extensions are R79 a month each, additional phone numbers R18 a month, and call recording storage R1.80 per GB a month. The company publishes worked examples: one number and four extensions comes to R316, four numbers with ten extensions to R844, and twenty numbers with twenty extensions to R1,922, all excluding VAT |
| Call rates | Landlines R0.30 a minute and local mobile R0.69 a minute, excluding VAT. Billing is per second from the first second on all outgoing calls, which is more honest than per-minute rounding and worth having in writing. Calls between Buzzbox users and all incoming calls are free |

| Coverage | The company indicates the service works wherever you have an internet connection, so coverage is a function of your line rather than a footprint |
| ICASA licence | No ICASA reference is published. For a hosted phone service the licensed capacity normally sits with an upstream operator — ask whose network your numbers live on and what happens to them if you leave |

The whole rate card, in public, with worked examples
Very few providers in this directory publish enough detail for you to calculate your bill before speaking to anyone. Buzzbox publishes all of it: the per-extension rate, the per-number rate, both call rates, the recording storage cost, and worked monthly totals at three different sizes. A four-person office with one number is R316 a month excluding VAT before calls, and you can check that arithmetic yourself. For a small business that is a genuine service, because the alternative is three quote forms and a week of waiting to find out the same thing. Two details raise the quality further. Per-second billing from the first second means a fifteen-second call costs fifteen seconds rather than a rounded minute, which on a high volume of short calls is a real difference. And free calls between Buzzbox extensions plus free incoming calls means the internal traffic that dominates many small offices costs nothing. The gaps are worth naming too. Support runs 09:00 to 17:00 on weekdays with nothing published outside that, so if you take calls in the evening establish what cover exists. There is no founding year and no Google profile to consult, so the usual background checks come up empty and the diligence has to happen in conversation. Ask how long they have been trading and for two references of your size. Compare the wider market in the cloud PBX directory.
Who Buzzbox is a fit for
- Small offices that want to calculate the monthly cost before contacting anyone
- Businesses making many short calls, where per-second billing genuinely saves money
- Companies whose call volume is mostly internal and inbound, both of which are free
