ABSTRACT:
A telephone with a mute ringer function having an automatic disabling feature includes multiple call indicators including a ringer. A power output reducing device is connected to the ringer to reduce the ringer volume prior to a connection between the telephone and a remotely located telephone. A volume switch control unit is connected to the power output reducing device to reset the ringer volume to a level established prior to a volume reduction upon detecting either connectivity to the remotely located telephone or the termination of the connection. A selecting device selects an incoming call indicator prior to the connection to the remote telephone. A reverting device automatically reverts power to a previously selected incoming call indicator upon either establishing connectivity for the call or the termination of the call. In a preferred embodiment, the ringer power output reducing device and the ringer power output resetting device include a volume switch connected to the ringer.
