MWCOM Cloud PBX vs On-Premise PABX
Quick Answer
A PBX (Private Branch Exchange) is a business phone system that routes calls between your extensions and the outside world. MWCOM cloud PBX is hosted (no office PBX box): system fees from R299/mo ex VAT for up to 5 extensions, calls at R0.32/min to Telkom landlines and R0.60/min to other networks, number porting from R180 + VAT, with optional LTE failover at R499/mo. Setup is typically fast via apps; on-premise PABX still means R15,000–R80,000+ hardware.
Definition

Comparison
Cloud PBX vs On-Premise PBX
Cloud PBX is hosted by your provider with a monthly system fee; on-premise PBX is a hardware box you buy, install, and maintain in your office.
| Feature | Cloud PBX (MWCOM) | On-Premise PABX |
|---|---|---|
| Upfront hardware cost | R0 | R15,000–R80,000+ |
| Monthly system fee | From R299/mo ex VAT | Maintenance + calls |
| Setup time | Hours–days (apps) | 2–6 weeks |
| Remote / mobile access | Mobile + desktop apps | Limited without extra setup |
| If internet drops | Mobile app + optional LTE R499/mo | Desk phones often dead |
| POPIA compliance | SA-hosted by design | Depends on your setup |
| Hardware upgrades | Automatic (provider-managed) | Hardware replacement cost |
Bottom line: For most South African SMEs with 2–50 staff, cloud PBX costs less, installs faster, and supports remote work without capital hardware. On-premise PABX may suit large enterprises with existing hardware investments and dedicated IT teams.
Terminology
PABX vs PBX: What Is the Difference?
A PABX (Private Automatic Branch Exchange) is simply an automated version of the original PBX — the "A" was added when systems became automatic rather than operator-switched. Today the two terms are used interchangeably.

Ask us on WhatsAppA PBX (Private Branch Exchange) is a private business telephone system that connects staff on short extensions and routes calls to/from outside lines. Modern cloud PBX does that over the internet with no on-site PBX box — staff use a desk phone, desktop app, or mobile app.
PBX is not outdated — the hardware box in the cupboard is. South African SMEs still need extensions, IVR, hunt groups, and call recording; those features now usually ship as cloud / hosted PBX (same category as MWCOM), not a capital PABX purchase.
PBX and PABX mean the same thing in practice. PABX (“Automatic”) is the older tender-doc term. IP PBX / hosted PBX / cloud PBX are internet-based versions of that same business phone system.
Cloud PBX is hosted by the provider for a monthly system fee (MWCOM from R299/mo ex VAT for up to 5 extensions). On-premise PBX is a physical box you buy (often R15,000–R80,000+), install, and maintain. Cloud wins for most SMEs on speed, remote work, and capex.
MWCOM cloud PBX system fees: Essential R299/mo (up to 5 extensions), Professional R899/mo (up to 15), Enterprise R2,999/mo. Calls are separate at R0.32/min Telkom landline and R0.60/min other networks. Unlimited calling is quote-only. On-premise still adds hardware capex.
VoIP is the technology that carries voice over the internet. A PBX is the system that manages extensions and call routing. A cloud PBX uses VoIP — complementary, not alternatives. For the full VoIP feature/cost pack see /voip-phone-systems-south-africa.
Yes. MWCOM ports existing geographic (and often 0800/087) numbers. Porting starts from R180 + VAT — not free. Timing depends on the donor network; we keep service continuous during the cutover where the process allows.
