What PortaOne Does
PortaOne is a telecom software company headquartered in Chernivtsi, Ukraine, with offices in the US and Canada. The company develops PortaSwitch — a unified service management and delivery platform that combines convergent billing, online charging, and Class 4/5 SIP softswitch functionality in a single system. PortaSwitch is deployed by over 500 telecoms operators worldwide.
The platform handles voice, messaging, IoT/M2M, and data traffic within a converged network. PortaOne delivers more than 20 software builds per year, with new features released approximately every seven weeks, and provides full API access along with source code availability for customisation and integration.
Core Platform: PortaSwitch
PortaSwitch combines two core components. PortaBilling is the convergent billing and online charging system, handling real-time rating, invoicing, and revenue management across multiple service types. PortaSIP is the Class 4 and 5 SIP softswitch, managing call routing, number management, and voice service delivery.
Together, these components allow service providers to launch and manage VoIP, UCaaS, SIP trunking, MVNO, IoT, and messaging services from a single platform without needing to integrate separate billing and switching systems. The platform supports multi-tenant architecture, enabling operators to provision resellers, sub-brands, and wholesale customers within the same deployment.
PortaAIM: AI Monetisation
PortaOne’s newest product, PortaAIM, is an AI billing platform designed for revenue management around AI-based services. Announced at MWC 2025, PortaAIM enables telecoms operators and startups to monetise AI services with flexible pricing models, automated billing, and real-time cost optimisation. This positions service providers to offer and bill for AI-driven applications alongside traditional telecom services.
Key Use Cases
PortaSwitch serves several specific deployment models relevant to the South African market. For SIP trunking providers, it offers a single platform to manage wholesale and retail voice services with real-time billing. For UCaaS/Cloud PBX operators, it provides the billing backbone needed to launch hosted PBX services with per-seat or per-minute charging models. For MVNOs, it supports real-time charging and flexible service plan creation — PortaOne recently enabled Nigeria’s first tier-3 MVNO, Vitel Wireless, and helped launch Sierra Leone’s first 5G operator in under three months.
Why SA Resellers Should Know About PortaOne
For South African resellers considering launching their own branded voice or UCaaS services — rather than simply reselling another provider’s platform — PortaSwitch offers the billing and switching infrastructure to do so. The platform’s multi-tenant capabilities mean a reseller could theoretically operate as their own service provider, managing their own customer base, pricing, and billing independently.
PortaOne’s track record across 500+ operators globally, combined with its rapid release cycle and source code access, makes it relevant for any SA telecoms business evaluating whether to build or buy their service delivery platform. The addition of PortaAIM also signals where PortaOne sees the market heading — toward AI service monetisation as a natural extension of traditional telecom billing.
