Description
IP-based voice telephony (VoIP) and the SIP protocol are clear examples of disruptive technologies that have revolutionised a previously settled market. In particular, open-source solutions now have the ascendancy in the traditional Private Branch eXchange(PBX) market.
We present a possible architecture for the modernisation of CERN's fixed telephony network, highlighting the technical challenges to be addressed and the critical services that must be maintained and then describing how the introduction of open-source call routers based on the SIP protocol and Session Border Controllers (SBC) could foster the introduction of new services and increase the agility of our telephony network to adapt to new communication standards.
