Hosted PBX for South African Businesses
Move your business phone system to a managed cloud PBX with call routing, queues, reporting and number-porting support. Stem Connect designs Hosted VoIP PBX around your connectivity, users and call flows so voice stays reliable in day-to-day operations.
Hosted PBX, in buyer language
Hosted PBX, also called hosted VoIP PBX, cloud PBX or hosted IP PBX, replaces a traditional on-site phone system with a managed cloud service. Stem Connect designs and supports business PBX deployments for South African teams in Johannesburg, Cape Town and Durban, including number porting, call routing, IVR, queues, reporting and integration with your existing fibre, WiFi and security stack.
What you get
The strongest Hosted PBX rollouts start with call structure and network readiness, then add features around the way the business actually handles calls.
Call routing and IVR
Route callers cleanly before they reach the wrong team or get missed.
- Auto-attendants and department routing
- Ring groups for reception, sales and support
- Time-of-day and after-hours routing
- Overflow paths for busy or unavailable teams
Queues and reporting
Give managers better visibility into call volume, missed calls and team handling.
- Hold queues for call-heavy teams
- Call recording where enabled and appropriate
- Real-time and historical reports
- Useful operational visibility for service teams
Numbers and porting
Keep or add business numbers with realistic checks before cutover.
- Geographic numbers such as 011, 012, 021 and 031
- 087 and toll-free number options where supported
- Porting where supported and subject to network availability
- New numbers for teams, departments or branches
Voicemail and forwarding
Keep calls moving when people are away from desks or working across locations.
- Voicemail-to-email options
- Call forwarding and find-me/follow-me flows
- Mobile twinning where supported
- Cleaner handling for distributed teams
Scalability
Add capacity without replacing an on-site PBX or reworking every site.
- Add users, departments and locations
- Add queues as teams grow
- Standardise call flows across branches
- Support hybrid and distributed teams more cleanly
Connectivity-aware design
Hosted PBX works only as well as the network behind it.
- We check fibre, WiFi and failover readiness
- Stable fibre is recommended where voice is critical
- LTE or wireless failover can be planned where appropriate
- Segmentation helps keep voice traffic predictable
Buyer concerns we plan around
Hosted PBX buying decisions usually come down to quality, continuity, porting risk and whether the provider understands the network underneath the phone system.
Call quality
Voice is sensitive to jitter, packet loss and poor WiFi. We check the connection before rollout and recommend fibre, segmentation or failover where needed.
Number portability
Keep your existing geographic and 087 numbers where porting is available, or add new numbers for teams and branches. Port-out timelines depend on the losing operator.
Scalability
Add users, departments, queues and locations without replacing an on-site PBX.
Microsoft Teams / CRM integration
Add Teams Calling, CRM or reporting integration where the platform and customer environment support it.
Support and SLA
Local South African support with a clear escalation path. Exact service levels depend on the solution and commercial agreement.
Johannesburg, Cape Town and Durban
Stem Connect supports Hosted PBX deployments in Johannesburg (Sandton, Rosebank, Randburg, Midrand), Cape Town (CBD, Century City, V&A Waterfront, Bellville), and Durban (Umhlanga, La Lucia, Westville, Pinetown). Business connectivity feasibility is checked address-by-address before rollout.
