Voice evolution

  • Published:

Abstract

This paper explores the future of voice in BT, in terms of market drivers, technology solutions and simple economics. It considers the overall market for voice services in the UK and the directional conclusions which may be drawn. The pressures on the current PSTN platform are explored along with potential solutions to these issues. The paper then goes on to review voice over IP services which range from best-effort, Internet-based through to high-quality corporate services, and provides a perspective on the market for these services, together with their technical maturity. The paper then reviews the opportunities provided by multimedia calling, and explores how these services can be delivered. Taking these areas as a whole, it then proposes a flexible architecture which can be used to deliver all of these services in the context of an uncertain future market-place, providing the flexibility required to mitigate against the uncertainties in both the current and future market environments.
