The latest Plantronics hands free device is a DECT 6.0 phone. By updating the underlying cordless phone technology it has eliminated all issues associated with WiFi interference and other associated conflicts. Other benefits of the upgrade include improved voice clarity, extended talk time and improved range.

The Plantronics CT14 also supports caller ID and waiting. Up to six dial-pads can be registered on a charging station. In addition to sharing lines, users can intercom one another and participate in three way calls. Dial pads can also be registered with up to four different charging bases. In the event that one is out of range or unavailable for whatever reason, a dial pad can be programmed to automatically search for another.
