Last week I got into some debates about the death or evolution of the PBX. The bigger point though is how complex things are becoming to define in communications. It is a far bigger issue than “PBX.” What is Unified Communications? What is Cloud? What is open? What’s the point of all this communications technology if we can’t agree on language and terminology? Add to the list the term “Server.” I am not sure what a server is any more. Are you?
