A method of managing communications between communication devices within a digital intercom system includes providing input and output tables for each communication device. The tables for each device are made up of cells formed from linear arrays corresponding to communication channels and the other devices. When two devices communicate on a given channel, a cell in the appropriate input and output table is identified based on the channel and the devices communicating. The cells provide volume control information which can be relied upon to determine if or to what degree audio signals should be transferred between the devices.

The invention relates, inter alia, to a speech station (10) for an intercom network (11), comprising an in particular parallepipedal housing (12), with a housing front (13) and a rear housing side (14), wherein a plurality of programmable operator controls (15a, 15b, 15c, 15d) and multiple displays (16a, 16b, 16c, 16d) are tightly packed on the housing front (13), wherein the operator controls comprise a plurality of selector keys (17a, 17b, 17c, 17d), wherein the speech station as a result of a selector key being actuated by an operator provides a direct listen and/or talk connection to a selected other speech station (18a, 18b) of the intercom network via a switching station (19), wherein a plurality of connectors (20a, 20b, 20c, 20d), such as power-supply connector, data cable connector, BNC connector, are mounted on the rear housing side (14), wherein at least one loudspeaker (24a, 24b) is fixed on the speech station, wherein the loudspeaker is accommodated in a seat (25) between the housing front (13) and rear housing side (14), offset to the rear (26) relative to the housing front (13), and wherein the loudspeaker (24a, 24b) has a sound exit surface (27) from which the sound is propagated to an opening (28) in the housing front (13), wherein the opening has an opening cross-section (29) that amounts to only a fraction of the sound exit surface (27).

A digital intercom system has a master station with hardware and software configured to allow duplex communication between a plurality of communication devices. The software is configured to run a plurality of settings for directing communication between the communication devices, the settings including a plurality of channels for each communication device. The channels each define parameters for how the communication devices within the system will communicate. An audio output device is linked to a corresponding communication device of the plurality of communication devices such that the audio output device is configured to receive and play the same audio as the corresponding communication device. The master station is configured to modify the settings based on input entered into a browser based program run on an input/output (I/O) device by a user.

One embodiment provides a method, including: employing a first device for a call; automatically detecting a transfer requirement between the first device and a second device; and transferring, from the first device to the second device, the call in response to the detecting. Other aspects are described and claimed.

The present disclosure relates to a method, apparatus, and system for processing incoming calls. The method includes: determining whether a current state of a mobile terminal where a caller number is located meets an incoming call transfer condition in response to detecting that an incoming call is calling the caller number; and transferring the incoming call to a server in response to determining that the current state of the mobile terminal meets the incoming call transfer condition, for the server to send incoming call reminder information to a designated target application.

Systems and methods for optimized call handling during e911 calls. Normally, when a user equipment (UE) is connected to a public safety answering point (PSAP)e.g., is on a 911 callall incoming calls are automatically routed to voicemail. In contrast, the systems and methods disclosed herein enable calls that were dialed within a predetermined time window of the 911 call to be sent through to call-waiting to enable the user to accept or reject the call. The system can use a guard timer to determine whether a call is within the predetermined time window. The system can include a single guard timer for all incoming callse.g., any call made from the UE within the previous X minutes prior to the 911 call. The system can also include individual guard timers for each call that expire separately relative to the call's proximity to the 911 call.

In a communication system, a PBX, a smartphone, and a communication adapter are connected. When detecting an event related to a call such as an incoming call and an outgoing call, the communication adapter transmits information on the event to the smartphone through BLE communication with the smartphone. The smartphone makes a notification of the occurrence of the event, based on the information on the event transmitted from the communication adapter. After the notification of the occurrence of the event, the communication adapter transmits an Invite command, 180 command, or the like to the PBX.

The invention relates to, among others, a network device (10, 11, 12) for an intercom network (13) for permitting an audio communication, in particular a duplex audio communication with other users (14a, 14b, 14c, 14d, 14e, 14f) of the intercom network, comprising a housing (33) and a communication module (20a, 20b) arranged therein or thereon, with which a radio link can be established for the transmission of audio signals to another user, wherein the radio link is subject to the DECT protocol. The speciality, among others, consists in that the network device (10, 11, 12) comprises a means (21) for preventing or reducing multipath interferences.
