Over the next few years IP telephony will replace conventional telephone technology (also known as Time Division Multiplex, TDM for short) across much of Europe. In Switzerland, the changeover is scheduled to be completed at the end of 2017. In discussions with partners and customers, I have found that this is mostly seen as an opportunity. The changeover, and the use of UCC in particular, opens up new possibilities and applications which were unthinkable up to now with conventional TDM technology. They not only change telephony but offer a great deal besides. We could exaggerate slightly and say that this is perhaps even a minor reformation of the way in which we communicate. In this blog article I would like to go into a little more detail about the opportunities offered by the use of UCC.
