Switch Call Audio Between Your Calisto and a Headset
To switch call audio between your Calisto speakerphone and any connected headsets, do one of
the following:
•When you are not on a call: Press Audio Options
. If you have one headset connected to your
Calisto, pressing this key switches from the speakerphone to the headset and back. If you have
more than one headset connected to your Calisto, pressing this key opens the Audio Devices
screen. Select the device you want to use. This device now becomes the default audio device—
audio for new incoming calls plays over this device unless you change it.
