Can I pair a different Bluetooth headset for use with the Calisto handset?
Yes, a different Plantronics headset can be paired with the Calisto Pro Series handset. It is not recommended to pair other non-Plantronics headsets as both the sound performance and the headset interaction with the unit are not guaranteed. In addition, unless the headset paired with the Calisto handset supports Multi-point capability, it will not be able to answer both landline and mobile calls.
