Easily forward your Skype for Business and Lync calls from your PC to your smartphone using Jabra Intelligent Call Transfer (JICT). This is ideal for when you need to leave your office or desk. Users can connect the headset to all their devices, such as smartphones or tablets, via the 3.5mm jack to work or listen to music. The optical call indicator automatically lights up at the start of a call, signaling the employee's unavailability. The busy light can also be manually activated to allow for uninterrupted work. The headset's special ear cushions filter out high-frequency sounds, such as voices. Jabra refers to this as "passive noise cancellation.".
