The T48G is also built for the Gigabit Ethernet and facilitates very rapid call handling and the application of accessories such as a Bluetooth USB Dongle, plus wired and wireless headsets. The new IP Phone supports impressive productivity-enhancing features too which make it the natural and obvious efficiency tool for today’s busy executives and professionals.
