ringtone for the mobile phone call is heard in the headset. Tapping the PC call button on the
headset will end the PC softphone call. Tapping the mobile call button will answer the mobile
phone call.
NOTE
Answering the call on your mobile phone sends the audio to the mobile phone and leaves the
PC softphone call active on the headset.
