The Total Fixed Voice Subscription and Revenue Forecast: 2018–23 is part of Ovum's fixed forecast series, which provides in-depth projections of KPIs for the fixed voice market to 2023. It includes subscriptions by technology, service revenues, subscription revenues, and call revenues.


  • On a global basis, service revenues from fixed voice services are expected to decline at a CAGR of -5.64% between 2018 and 2023, from $142bn in 2018 to $106bn in 2023. The largest declines in absolute terms will occur in the markets of Africa (-10.50% CAGR), Central and Southern Asia (-7.79%), and Eastern Europe (-7.50%).
  • Globally, fixed voice subscriptions will fall from 931 million in 2018 to 821 million in 2023, a CAGR of -2.49%, driven by fixed-to-mobile substitution. This decline is far slower than the decline in revenues due to the impact of bundling.
