Changes to the telephony landscape

In the last few years, there have been significant changes to how telephony services are provided driven by the convergence of telephony and data communications. The use of voice over IP gives greater flexibility for users and reduced costs for both providers and users.
The PTT’s online course “Telephony and data services” gives a comprehensive overview of how communications services are provided, and the facilities available to residential and business users
A new module of the course covers the provision of telephony for businesses with emphasis on IP telephony and Internet telephony service provision.
This “Telephony and data services” course, which is aimed at communications technicians and managers, is suitable for use in digital apprenticeships.
