A system and keypad interface is disclosed that allows users to communicate with non-verbal cues. Embodiments include an optimal key pattern(s) to minimize human time using the control interface. Aspects of the system block the natural reading process and rely on pattern recognition, thus users can enter and respond to messages more quickly without the cognitive upset of reading messages that rely solely on left to right or vice versa. The grouping of the keys optimizes or minimizes the time a human uses the control system based on how the human brain interprets visual information. Some embodiments include messages delivered by tones associated with button presses. The tones may provide a non-verbal communication without the recipient needing to see the panels.

An object is to provide an incoming-call number notification apparatus capable of notifying a user of the number of incoming calls at the present moment by using simpler equipment. An incoming-call number notification apparatus according to the present invention includes a control unit (14, 15) configured to, when there is an incoming call to a plurality of telephones (20) accommodated in an exchange (10), determine a display color according to the number of incoming calls at the present moment, and instruct the plurality of telephones to blink or light up an incoming-call lamp of its own telephone in the determined display color (20).

Multiple simultaneous calls are controlled. At least one processor is used to display an interface including indicators corresponding to at least two audio presentation devices. Each interface includes call contextual controls which change according to the state of a call. A swap control swaps an active call between the audio presentation devices corresponding to the indicators.

In some embodiments, the present invention provides for a computer-implemented method, including: causing, by a specifically programmed computer call management communication system, to transform, over a computer network, computing devices of users, into corresponding specialized call management devices, by having each computing device to execute a specialized call management client software application being in electronic communication with the specifically programmed computer call management communication system over the computer network by utilizing SIP; where the specialized call management client software application generates specialized graphical user interfaces configured to allow each user to concurrently initiate and maintain, over the computer network, a plurality of voice communications of distinct types with other users, by, for example, allowing each user to independently and dynamically divert, in real-time, any voice communication of any type to any audio device associated with a corresponding specialized call management device of such user.

An intercom system for an apartment house according to the invention includes room units (10A, 10B) which are installed in respective rooms of the apartment house, and a control unit (20) which is connected to the room units (10A, 10B) of the respective rooms via an intercom line (L1) so as to be capable of communicating therewith, and is capable of communicating with an external server (S) via an external communication network. The control unit (2) acquires, based on a request signal transmitted from the room unit (10) via the intercom line (L1), predetermined information corresponding to the request signal from the external server (S) via the external communication network, and transmits the acquired predetermined information via the intercom line (L1) to the room unit (10) which transmitted the request signal.
