What is VoIP and why are South African businesses switching from landlines?
VoIP (Voice over Internet Protocol) converts voice calls into digital data packets transmitted over your internet connection — eliminating the need for a traditional copper landline. For South African businesses, this typically reduces monthly call costs by 40–60% while adding features like call recording, auto-attendants, and mobile apps that work from anywhere.
Traditional landline systems in South Africa are maintained by Telkom on ageing copper infrastructure. VoIP runs on fibre or LTE — the same connection your business already uses for internet. MWCOM combines business fibre with VoIP on a single infrastructure, so if fibre fails, the 4G failover keeps your phones online automatically.
Traditional landline
- ❌ Copper infrastructure — Telkom maintenance delays
- ❌ Per-minute billing adds up fast
- ❌ No mobile app — tied to desk
- ❌ No call recording or IVR without expensive hardware
- ❌ Line fails during power outages
MWCom VoIP
- ✅ Runs on your existing fibre connection
- ✅ Unlimited SA calls from R299/month
- ✅ Mobile + desktop app — work from anywhere
- ✅ Call recording, IVR, call queues included
- ✅ 4G failover keeps phones alive if fibre drops
SIP Trunking vs Cloud PBX vs Hosted PBX — explained for SA businesses
The difference between SIP trunking, Cloud PBX, and Hosted PBX comes down to where the phone system intelligence lives — on your premises, in the cloud, or managed entirely by your provider.
SIP Trunking
Replace landlines onlySIP (Session Initiation Protocol) trunks replace your physical phone lines with virtual lines over the internet. You keep your existing on-premises PBX hardware — SIP trunks just connect it to the internet instead of copper. Best for businesses with existing PBX hardware they want to keep. MWCom SIP trunks start from R199/trunk/month.
Cloud PBX (Hosted PBX)
Full phone system in the cloudCloud PBX moves the entire phone system to a server managed by your provider. No on-premises hardware needed beyond IP phones or a softphone app. You get call routing, IVR menus, call recording, and extensions managed from a web dashboard. MWCom Cloud PBX starts from R299/month for up to 5 extensions.
Hosted VoIP
Apps on any deviceHosted VoIP is Cloud PBX accessed via mobile and desktop apps — no physical IP phones required. Employees use their smartphones or laptops as their office phone. Ideal for hybrid and remote SA teams. Included in all MWCom VoIP packages.

Ask us on WhatsAppVoIP (Voice over Internet Protocol) transmits phone calls as digital data over your internet connection instead of copper telephone lines. For South African businesses, VoIP typically costs 40–60% less than traditional landlines, includes features like call recording and mobile apps, and runs on the fibre or LTE connection you already have.
Yes. South African businesses switching to VoIP save an average of R2,800/month (MyBroadband Business Survey, 2025). Traditional Telkom landlines charge per minute for all calls including local calls. MWCOM VoIP includes unlimited SA landline and mobile calls from R299/month — a flat monthly fee with no per-minute surprises.
MWCOM offers the only VoIP service in South Africa with a Johannesburg-based support team available during business hours. Wanatel, Vox, and WebAfrica route support through call centres or offshore teams. MWCOM assigns a dedicated account manager to every business VoIP customer, reachable by WhatsApp.
Fibre is strongly recommended for business VoIP — it provides the low latency and stable bandwidth needed for clear calls. A minimum of 1 Mbps per simultaneous call is required. LTE/5G can work as a primary or backup connection. MWCOM provides both business fibre and VoIP, with automatic 4G failover so calls stay live even when fibre drops.
A SIP trunk is a virtual phone line delivered over the internet that replaces a traditional copper telephone line. If your business already has an on-premises PBX phone system, SIP trunks connect it to the internet for calls — no hardware replacement needed. MWCom SIP trunks start from R199/trunk/month with number porting included.
Yes. MWCOM handles full number porting for 011, 021, 031, 041, and all other SA geographic numbers, as well as 087 non-geographic numbers. Porting typically takes 5–10 business days and your service continues uninterrupted during the transition. Porting is free on all MWCOM VoIP packages.
VoIP is the underlying technology — transmitting calls over the internet. A Cloud PBX is the phone system built on top of VoIP — it handles call routing, extensions, IVR menus, call queues, and recording. MWCOM provides both: VoIP as the transport and Cloud PBX as the full phone system, managed from a web dashboard.
Business VoIP in South Africa starts from R299/month for a Cloud PBX with up to 5 extensions and unlimited SA calling (MWCOM). Wanatel and WebAfrica are similarly priced. Telkom VoIP starts from ~R599/month with setup fees. Enterprise packages with more extensions and dedicated SIP trunks range from R999–R2,999/month.
