Calisto Pro: Headset Specifications

The Calisto headset uses Bluetooth technology, and can be paired with other Bluetooth devices (click here for more information).

The headset includes call answer/ end control, volume adjustment, redial and voice dialing. All of these features work across landline, VoIP and mobile calls except for voice dialing (which is only available for use with mobile phones) and redial from the headset (which is not available for VoIP calls).  Please note that the headset does not have a mute feature (although the handset does).
