This study focuses on the South African PBX, Hosted PBX and Unified Communications (UC) markets. BMIT has analysed the South African PBX market over the past fifteen years and has expanded the scope of the study in recent years to include a wider range of emerging technologies, including the Hosted PBX market and UC markets.

Study focus areas and objectives

The study provides market sizing and segmentation of the premises-based PBX/CBX/IPT, Hosted PBX and UC platform markets, including unit shipments and/or endpoints, average selling price, revenues, and market shares per segment. It also includes an analysis of how convergence and technology trends impact on players in these markets, and how they are positioning themselves to capitalise on new opportunities.

Hosted PBX and UC markets are researched both as platforms and as services. The platform element consists of the number of active seat licences and the ARPUs they attract, the number of attached terminals and the equipment revenue value of IP terminals shipped in each year. The services element consists of revenue analysis derived from licences, i.e. up-front charges versus annuity revenue.

Unified Communications analysis includes the impact of Microsoft and PBX vendors’ own offerings and other UCaaS and virtual telephony offerings .

Quantitative analysis and forecasts

Working off an historical database for the various segments, BMIT uses quantitative and qualitative inputs received from interviews with PBX and UC system providers against the backdrop of previous year’s market models, to arrive at the best estimates of growth rates.

An installed base model is also constructed to develop a credible model of future growth forecasts, including shipments into new sites and the replacement market. The study also draws on secondary research, including a review of international trends, to inform the local market forecasts.
