In a messaging system, a messaging server transmits signals over the telephone network to be received by equipment at, e.g., the customer premises. The receiving equipment converts the signals into meaningful information (e.g., written or audible words, audible tones, and / or lights), and provides that information (e.g., by audible announcement and / or visual display) to the user. The signals can be of a variety of types. For example, the signal can be the Incoming Caller Line Identification (ICLID) signal associated with an incoming telephone call. Alternatively, the ICLID signal can be can be sent with the set-up of a non-associated telephone call, and can correspond to a message code, such as to provide the recipient with notification information such as emergency notification messages. Such notification information can be substantially simultaneously transmitted to a number of sets of receiving equipment (e.g., all homes in a given region). The notification information need not be transmitted alongside an incoming telephone call, and can be received regardless of whether the telephone equipment at the customer premises is on- or off-hook. The receiving equipment can display and / or announce the information, e.g., in the user's preferred language.

An on-hook EOH indicating telephone includes a parallel set detector, an EOH signal detector, and an indication module to activate a configurable audible and / or visual alert indicating that another telephone is off-hook and should be hung up. The audible alert may be a unique ringing of the otherwise conventional ringer (e.g., every 5 minutes, at a unique cadence or frequency, etc.), or may be an audible tone output from the speaker of the on-hook EOH indicating telephone. The visible alert may be, e.g., a text message on a display of the on-hook EOH indicating telephone, a blinking, flashing, etc. of an LED, or other visible attention getting technique. When the central office presents the extended off-hook (EOH) notification signal to the desired telephone line, the invention-equipped telephone detects a parallel set in use, and then listens for the EOH signal. Upon receiving the EOH signal, the inventionequipped telephone will uniquely ring, visibly illuminate, flash, or otherwise alert the users in the household that another telephone is off-hook. This audible and / or visible alert at the on-hook EOH indicating telephone is over and above that audibly output by the parallel telephone which caused the receipt of the EOH signal.
