Our communication styles continue to change over the years. When only analogue communication was available, each phone line was assigned a specific telephone number. If the user moved and wanted to keep the same number, it was necessary to reroute the phone line.When IP started to gain popularity, it became possible to assign a telephone number to a specific device. Simply by moving the device, users could use the same number in different locations. Now, users expect that telephone numbers can be assigned to specific users, which can then be used from any device. As a result, users can conduct business communication not only inside the office, but even outside or at home, creating an opportunity to revolutionize their work style. The Panasonic KX-NSX series delivers the next generation of communication systems to meet todays work style.
