Can I keep my existing 011 Johannesburg number?

How long does setup take for a Johannesburg business?

Your Cloud PBX is typically configured and live within one business day. Our team handles the full setup — extensions, ring groups, IVR menus, time conditions and voicemail. If you're porting a number, that process runs in parallel and usually completes within 5–10 business days, during which your existing number continues working normally.

Can I connect my Sandton office and East Rand depot on the same system?

Yes. All Othos extensions are part of the same Cloud PBX regardless of physical location. Your Sandton office, East Rand depot and any staff working remotely are all on the same system — they share the same number range, ring groups and IVR, and internal calls between any extensions are always free.

How much does it cost compared to our existing PBX?

Most JHB businesses switching from traditional PBX hardware save 40–60% per month. You eliminate hardware maintenance costs, reduce per-minute call rates significantly, and pay one predictable monthly fee per user that includes all features. Othos pricing starts from R149 per month.

Does Othos support call recording for FAIS and POPIA compliance?

Yes. Call recording is included with your Othos plan. All calls are recorded and stored securely in the cloud — accessible, searchable and downloadable at any time. For Johannesburg's financial services sector, this supports FAIS compliance requirements. For all businesses, it supports POPIA obligations around customer communication records.

Can I get a new 011 Johannesburg number if I don't have one?

Yes. Othos can provision a new 011 geographic number for your Johannesburg business within minutes of signup. You can also choose a 010 or 087 non-geographic number, or have multiple numbers — one per department or branch — all routing through the same Cloud PBX.
