Yes, today's blog is about office phone systems. You have one. They are dull, necessary, and no one wants to deal with them. They need to be re-configured for new employees, they're confusing, and the telco lines probably cost you more money than you'd like.
Like everything else, office phone systems began transitioning to fully online/digital well over a decade ago. The proper term is " Voice over Internet Protocol" or "VoIP." In a practical sense, it means that your phone lines are no longer coming in over traditional, "plain old telephone" lines, or other standard protocols from the 1960s to the 2000s. Instead, voice signals are now being carried to your phone from the telco via the internet, such as your broadband connection.
