Problems this solves
Common business calling problems VoIP can help address
VoIP does not automatically solve poor connectivity. Call quality can be affected by available bandwidth, latency, packet loss, Wi-Fi conditions, network congestion and the configuration of the business environment.
High or unclear call costs
VoIP can provide clearer call-rate guidance, per-second billing and call bundles that help businesses understand how voice usage contributes to monthly costs.
Old landlines and inflexible voice infrastructure
VoIP moves business calling onto IP-based infrastructure, making it easier to combine calling with modern phone systems, cloud services and internet connectivity.
Business numbers tied to a current provider
Eligible numbers may be ported through the applicable South African porting process, helping businesses move providers without automatically losing their established contact number.
Remote staff using personal mobile numbers
VoIP can support business calling arrangements for remote and hybrid teams when paired with a suitable phone system, supported devices and reliable connectivity.
Disconnected branches and inconsistent call handling
VoIP can support centralised business calling across locations when used with Cloud PBX, compatible PBX systems or a planned multi-branch communication setup.
Limited control over incoming business calls
When paired with the right phone system, VoIP can support call routing, queues, ring groups, business numbers and better handling of customer enquiries.
Difficulty scaling as the business grows
Adding users, numbers, calling capacity or branches can be easier when voice services are planned around a flexible IP-based setup.
Poor visibility into call usage and billing
Suitable VoIP solutions can provide clearer call records, usage information and reporting options to help businesses review voice activity.
Call-quality issues caused by unsuitable networks
VoIP is dependent on the quality of the underlying network. SureTel can assess connectivity requirements and recommend suitable business internet, network design or backup options.

Connectivity and quality planning
VoIP relies on suitable business connectivity. A recommended solution should consider available bandwidth, concurrent calls, latency, packet loss, local network design, Wi-Fi conditions, voice prioritisation and backup internet requirements.
Geographic numbers where applicable
Business number options depend on availability, the relevant numbering range, geographic requirements and the selected service configuration.
Features, integrations and service configuration depend on your business requirements, existing phone environment, number-porting needs, selected connectivity and feasibility for any related internet services.
Compare
VoIP vs traditional landline for business
VoIP may be a strong fit when your business needs more flexibility, clearer voice cost management, Cloud PBX integration, support for remote teams or multi-branch calling. Traditional fixed lines may still suit some simpler or legacy environments. SureTel can assess your current setup and recommend whether VoIP, Cloud PBX, SIP trunking or another solution is the right next step.
| Consideration | Business VoIP | Traditional Landline |
|---|---|---|
| How calls are carried | Calls are carried over an IP network and suitable internet connection. | Calls are carried through traditional fixed-line telephone infrastructure. |
| Business flexibility | Can be combined with Cloud PBX, SIP trunking and other IP-based voice services. | Often more closely tied to a fixed line and legacy phone environment. |
| Remote and multi-branch support | Can support distributed teams when the voice environment, devices and connectivity are properly configured. | Remote and multi-branch setups may require additional systems or separate line arrangements. |
| Phone system integration | Works with hosted PBX, onsite PBX, SIP trunking and call centre platforms where compatible. | May require separate equipment or gateways to integrate with modern phone systems. |
| Call-cost model | Can provide per-second billing, call-rate guidance and selected bundle options. | Costs depend on the provider, line rental, destination charges and calling model. |
| Number continuity | Eligible numbers may be ported through the applicable process. | Existing numbers may remain tied to the current provider unless porting is arranged. |
| Quality dependency | Depends on suitable connectivity, network conditions and voice-priority planning. | Depends on fixed-line infrastructure and the local telephony environment. |
| Best suited to | Businesses that want more flexible, internet-based voice services and integration with modern communication tools. | Businesses with simple fixed-location calling needs or legacy infrastructure that is not yet ready to transition. |

FAQ
VoIP FAQs
What is business VoIP?
Business VoIP is a voice service that allows a company to make and receive calls over an internet connection instead of relying only on traditional telephone lines. It can be used on its own or alongside Cloud PBX, SIP trunking and compatible phone systems.
How much does VoIP cost in South Africa?
SureTel VoIP call rates start from R0.30 per minute excluding VAT, with per-second billing where applicable. Final costs depend on call destinations, usage volumes, selected bundles, business numbers, phone-system setup and any related services.
Can I keep my existing business number when switching to VoIP?
Eligible business numbers may be ported through the applicable South African number-portability process. Porting depends on the number type, your current provider, required documents and successful completion of the process. SureTel can review your number-porting requirements before a move is planned.
Is VoIP suitable for remote and hybrid teams?
Yes. VoIP can support remote and hybrid teams when it is paired with a suitable phone system, supported user devices and reliable internet connectivity. Cloud PBX may be a suitable companion service when users need extensions, call routing or business phone features across different locations.
What internet connection do I need for VoIP?
VoIP needs a stable internet connection with enough capacity for the number of simultaneous calls your business expects. Call quality can be affected by bandwidth, latency, packet loss, congestion, Wi-Fi conditions and network configuration. SureTel can assess whether business fibre, wireless internet or a backup connection should form part of the solution.

What is the difference between VoIP and SIP trunking?
VoIP is the broader method of making calls over an internet connection. SIP trunking is a specific way to connect a compatible existing PBX or PABX system to VoIP calling capacity. Businesses with an existing PBX may consider SIP trunking, while businesses needing a hosted phone system may consider Cloud PBX.
