Future Calling

The transformation of telephone services over the next decade

The traditional Public Switched Telephone Network (PSTN) has been an enduring feature of communications over the past century. It has allowed people to call each other across the country and indeed across the world. Its success is in part due to the capability and reliability of the underlying technology to support telephone calls. However, this technology both in the UK and elsewhere is now coming towards the end of its life, and the transition to modern technologies based on Internet protocols is now in progress. This talk discusses the motivation behind these changes along with the approaches proposed and in some cases already taken by communications providers around the world to manage this transition. It will also discuss the role Ofcom can play to ensure that all those affected, from individual consumers to commercial stakeholders, are informed and supported as the network evolves.
