Using a Cordless Device as a Remote Control When not being used to talk, the cordless handset/headset buttons can act as a remote control
device to change display contrast, volume, and mute settings on the host IP phone. For example,
in a remote handsfree conference setting, the chairman can use the volume and mute buttons on a
cordless device to adjust speaker levels and mute the microphone on an IP phone that is not
within his reach. HTML applications may also make use of the cordless device buttons but
functionality may differ among applications.
