Systems and methods are provided for managing and analyzing multi-party dialogs (e.g., call) between communication devices. A digital connection is established with each of a plurality of communication devices. The connection is switched between the communication devices from a POTS connection to digital connections, enabling the communication devices to communicate with each other via the computing device over the digital connections. Audio signals are part of a multi-party dialog between users of the plurality of communication devices. The received audio signals are split into corresponding first signals and second signals. The first signals are transmitted to the plurality of communication devices and are analyzed to produce measurements of features of the second signals. Feedback data is transmitted to at least one of the plurality of communication devices.

A method and relay for relaying messages. The relay includes tests reliability relating solely to messages estimated with error and taken in their form prior to error detection in order to be able to separate messages that are reliable and messages that are not reliable. The relay also includes a shaper unit having a channel interleaver and a modulator taking account only of the messages estimated without error and of those messages estimated with error that are reliable, this shaping being performed in soft form if at least one message estimated with error successfully passes the reliability test.

Systems and techniques are disclosed for establishing inbound calls and outbound calls involving inmates and outside parties. One exemplary technique receives input identifying authorized sources who are authorized to initiate and conduct calls with an inmate and stores a list of the authorized sources. The list, for example, can include telephone numbers, VOIP caller identifiers, and/or call privileges associated with the sources. The technique receives an inbound call directed to the inmate and determines whether the source of the inbound call is authorized or not, for example, by comparing information about the source with information in the list of authorized sources and/or based on the call privileges. If the source is authorized, the call is permitted. If not the technique routes the call to a payment interface for the caller to provide payment information.

A multiple dwelling house interphone system includes a collective entrance machine, a dwelling room master device, and a management master device. The collective entrance machine is for calling a visit destination by a visitor. The dwelling room master device is for responding to the call by a dweller. The management master device is for speaking with the dweller by a manager. The management master device includes a speech permissibility storage section and a speech control section. The speech permissibility storage section registers a permissibility of calling and speaking to the dwelling room master device for each dwelling unit. The speech control section controls the calling and speaking. The speech control section does not perform the calling control when a calling operation by the management master device is performed towards the dwelling room master device of a dwelling unit registered as unpermitted in the speech permissibility storage section.

A communications method comprising the following steps: establishing a single-hop, multi-channel wireless network comprising a plurality of half-duplex nodes that can simultaneously receive on multiple channels but that cannot simultaneously transmit on the multiple channels; using linear programming to establish a rapid-throughput transmission schedule for data transmissions between the half-duplex nodes; multicasting all the data transmissions in the network in multicast sessions according to the transmission schedule; using erasure coding to reconstruct data transmitted in a particular multicast session in instances where the entirety of the particular multicast session is not received at a given node because the given node was transmitting during part of the particular multicast session.
