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.
