Why businesses choose this
Full hosted cloud PBX
Enterprise-grade telephony delivered from the cloud — IVR auto-attendants, hunt groups, ring groups, queues, voicemail-to-email, call recording, time-of-day routing and live wallboards as standard.

Per-second billing, no call contracts, free internal calls between extensions and competitive local, national, mobile and international rates — cut telephony spend without losing features.
Crystal-clear HD voice
SIP trunking over fibre or LTE with QoS tuning, redundant carriers and SBC protection so every call sounds sharp and stays connected.

Desk phones in the office, softphones on Windows and macOS, and mobile apps on iOS and Android — one business number, one extension, wherever your team is.

We port your existing geographic, 087 and toll-free numbers from any South African provider with zero downtime on inbound calls.
Optional AI Voice Assistant — never miss a call
Add a smart virtual front desk that answers instantly, greets callers naturally and works 24/7 — capturing the caller, the reason and routing to the right team, booking meetings or taking detailed messages straight to your inbox and CRM.

Frequently asked
- What exactly is a hosted PBX?
- Your entire phone system runs in the Marveltec cloud instead of a box on your wall. You get every modern PBX feature — extensions, IVRs, hunt groups, recording, voicemail-to-email — without the upfront hardware cost or maintenance.
- Will the call quality be as good as a traditional line?
- Yes — usually better. We deliver HD voice over SIP with QoS-tuned routers, redundant carriers and SBC protection. Where fibre is unavailable we use LTE or wireless failover so calls stay up.
- Do we need new phones?
- No. Use your existing SIP-compatible handsets, our free softphone apps on mobile and desktop, or we will supply and configure new Yealink hardware.
- Can we keep our existing numbers?
- Yes — we port your current geographic, 087 or toll-free numbers from any South African provider with no downtime on inbound calls.
- How much can we save?
- Most customers save 30–60% versus legacy Telkom lines thanks to per-second billing, free internal calls and lower local, mobile and international rates. We will benchmark your current bill before you switch.
- What about load shedding and outages?
- Because the PBX lives in the cloud, calls automatically reroute to mobile apps, alternate numbers, voicemail or the AI receptionist (if enabled) so your business keeps answering even when the office is dark.
- Is the AI Voice Assistant compulsory?
- No — it is completely optional. Many customers start with a standard hosted PBX and add the AI Voice Assistant later for after-hours cover, overflow or to handle high call volumes.
- How does the AI Voice Assistant sound?
- Natural and conversational, not robotic. It greets callers in your brand voice, asks clarifying questions, handles common requests end-to-end and hands over to a human when needed.
- Which languages does the AI support?
- English (South African and international accents) out of the box, with optional Afrikaans, Zulu and other languages on request. We tune voices and scripts to match your brand.
- Is our call data private and secure?
- Yes. Calls and transcripts are encrypted in transit and at rest, hosted in line with POPIA, and we never use your data to train third-party models.
