Every way your business makes a call.

Fraud monitoring runs 24/7/365 alongside specialist support, so unusual call patterns are picked up and acted on outside office hours as well as during them. On post-paid plans this limits the exposure a compromised extension can create before it is stopped.

Vox voice traffic runs across a fibre-backed network with points of presence in secure South African data centres and in the UK, each with failover and power redundancy, and direct interconnection to the major local networks. The network carries an average MOS score of 4.3.

In most cases, yes. Vox connects existing on-premise PBXs and SIP trunks through a managed or on-premise session border controller, and Direct Routing supports analogue phones and DECT systems, so legacy endpoints keep working while you move calling onto the Vox network.

Operator Connect is the quicker route: numbers and calling plans are allocated to Teams users from within the Teams admin centre, with no session border controller to run. Direct Routing suits businesses with existing SIP trunks, an on-site PBX, analogue or DECT endpoints, or branch sites needing survivability. The two can be combined, and a Vox voice specialist will map which users belong on which.

Uncapped Voice is a fixed monthly fee for unlimited calling on up to six simultaneous calls, suited to organisations of around 50 people or fewer that want a predictable bill. Cristal Voice is post-paid and rated per minute, so you only pay for what you use — the better fit for high outbound call volumes, with rates matched to your traffic.

No hardware to buy or maintain, no capex, predictable per-user pricing, one number across every device, loadshedding resilience, and a single accountable partner for the system, the lines and support — all delivered over a Tier 1 SA voice network Vox owns and operates.

Yes. Vox ports your existing geographic and non-geographic numbers across to any of our voice or PBX solutions, fully project-managed end to end, so your customers keep dialling the same numbers.

Because the system lives in the cloud, calls can fall back automatically to the mobile app on the same extension, so staff keep working from their phones. For sites that must never drop calls, Vox can design in redundant connectivity or, on Microsoft Direct Routing, a survivable branch appliance (SBA).

Yes. Vox's cloud PBX platforms run in geo-redundant, access-controlled South African data centres with encrypted signalling, fraud monitoring and continuous patching handled by Vox — typically a stronger security posture than an ageing on-site PBX a business maintains itself.

A cloud PBX is a business phone system hosted in a data centre rather than on hardware in your office. Extensions, call routing, voicemail, menus and queues all run as a managed service, and staff make and take calls through desk phones, desktop softphones or mobile apps — with nothing to buy or maintain on-site.
