Possible effects of botswana's telephone number change on design of telephone call charging systems

Abstract

The Botswana Telecommunications Corporation recently changed the structure of the national telephone numbers to seven digits. The change introduces two digit area codes in Botswana. The change also provides an increased exchange numbering range, and an effective and efficient management system for the growing customer base. This change not only affects all telephone subscribers but also the design of telephone call charging systems and billing software. The design of call charging systems is based on the structure of the national and international telephone numbering scheme in a country. A change in this structure therefore affects the design of call charging systems. This paper examines the effects of this change on the design of call charging and billing systems.
