ABSTRACT
The telecommunications industry has undergone a phenomenal transformation in recent years. Ever since its inception more than a century ago, the worldwide telecom network has enabled universal interpersonal voice communication. The exact modalities under which this service has been provided have evolved over time, often because of technical changes: from connection through a human operator to electromechanical to electronic switches, from only local or national calls to seamless international calls, from fixed-line access to wireless access, from one basic service to a myriad of value-added services.
