The growth in the importance of Internet-based services and the decline in fixed line telephony revenues has led to an increasing number of  telecommunication providers introducing next generation networks (NGNs).

This migration from circuit switched Public Switched  Telephone Networks (PSTNs) to telephony services based on Voice over IP (VoIP) promises operational cost savings for operators and innovative new services for customers. Ultimately, an NGN with an IP Multimedia Sub-system (IMS) could provide all fixed line and mobile services.

PTT already offers an online course introducing next generation networks and has now released an updated version of the existing “Voice over IP” course which introduces the principles and basic operation of VoIP.

A companion course “VoIP systems” which expands upon the principles covered by the updated “Voice over IP” course to cover such topics as the provision of a PSTN emulation service over an IMS-based NGN will be released soon.
