Imply IT runs the PBX, the line it rides on and the IT around it
Imply IT approaches telephony as an engineering outfit rather than a pure voice reseller. Its cloud PBX can be hosted in its redundant data centres or installed on site, the calls are billed per second with on-net calls free, and its own VoiceStack software gives finance a view of who is calling whom and what it costs. Because the same team sells business fibre and managed SD-WAN, it can carry the VoIP traffic over a link it manages end to end, which is the usual cause of call-quality complaints elsewhere. The trade-off is scale: this is a Durban company with satellite reach into Gauteng and the Cape, not a national carrier, so businesses outside those regions should ask how on-site work is handled.
Who Imply IT is a fit for
- KwaZulu-Natal businesses that want their phone system, internet and IT support from one local engineering team.
- Companies replacing an ageing on-premise PBX that want the choice of hosted or on-site, rather than being pushed to the cloud by default.
- Firms that need call accounting and recording across several extensions or branches, where VoiceStack’s billing and reporting earns its keep.

What phone system does Imply IT offer?
Imply IT supplies a PBX that can be hosted in its redundant data centres or installed on your premises, with VoIP calling, voice recording, geographic number porting, PBX hardware and SIP handsets, engineered on Linux telephony (Asterisk). Its VoiceStack software adds billing and reporting across extensions, and a quote scopes the handsets, extensions and features to your headcount and sites.
How much does a hosted PABX through Imply IT cost?
Imply IT does not publish a rate card. Ask for the per-extension monthly charge, the call rates (billing is per second, with on-net calls free), handset purchase or rental, and installation to be itemised separately from the monthly fee, and confirm the SLA tier that applies to your site. For reference, the 11 verified Cloud PBX providers on WhichVoIP that do publish prices charge R49–R79 per extension per month, with call rates and handsets on top, so expect a quote in that band unless the bundle includes hardware.

Where is Imply IT based and which areas does it serve?
Imply IT’s head office is at 46 Adelaide Tambo Drive in Durban North, KwaZulu-Natal, and it describes footprints in Gauteng and the Western Cape. Hosted PBX and VoIP can be delivered anywhere with a suitable internet link; ask how on-site installation and support are handled outside KwaZulu-Natal.
Can Imply IT supply our fibre and IT support as well as the phones?
Yes. Alongside voice, Imply IT sells business fibre, managed SD-WAN, Microsoft 365 and Azure services, cybersecurity, hardware, structured cabling and outsourced IT support. Carrying the VoIP over a link it manages itself lets one team own call quality end to end.
Does Imply IT’s phone system keep working during load-shedding?
A hosted PBX keeps running in Imply IT’s data centres during an outage at your office, but your handsets, router and fibre equipment need a UPS or inverter to stay on the call. An on-premise PBX needs backup power for the PBX itself as well. Ask Imply IT to scope backup power for the equipment that has to stay live.
Can we keep our existing numbers when moving to Imply IT?
Yes. Imply IT offers geographic number porting and provisioning, so existing landline numbers can be moved onto its VoIP platform. Porting in South Africa typically takes a few working days once the paperwork is in; confirm the timeline and any porting fee at quote stage.
How does Imply IT compare with other Cloud PBX providers in South Africa?
Imply IT competes as a regional managed-services house rather than a national carrier: its strength is the engineering team and the bundle of voice, connectivity and IT under one contract.
