Incoming Intercom Call Features

Incoming Intercom
By default, the IP phone allows incoming intercom calls to be automatically answered without
having to set up an Icom key on your phone. The phone automatically plays a warning tone when
it receives an incoming intercom call. It also mutes the microphone. If the intercom call comes into
the phone while an active call is already present, the phone puts the active call on hold and answers
the intercom call.
