  • Patent number: 11881989
    Abstract: A storage gateway serves as an interface between processes on a customer network and a service provider. The storage gateway is located on-premise with the customer processes. To customer processes, it appears that data is stored locally. However, the storage gateway interfaces with a remote storage service to store the data. For cached gateways, the primary data store is a remote data store, while frequently accessed data may be locally cached by the gateway. Reads may be satisfied from the local cache or from virtual data storage; writes are handled so as to appropriately update data blocks in the local cache and/or in virtual data storage. For shadowing gateways, the primary data store is the local data store; reads are passed through to a local data store, and writes are shadowed to virtual data storage as well as being sent to local data store.

  • Patent number: 11082558
    Abstract: A dialing list comprising call records can be processed by a call handling component(s) in a contact center in various dialing modes. A call record may be processed to originate a voice call, where the agent manually dials the call as a voice telephone call. In another embodiment, one or more call records can be processed to originate a SMS text call or group text call, where the agent also determines when the call(s) originates. The agent is presented with a graphical user interface tailored to the dialing mode. The dialing mode used may be defined by the dialing list the call record is retrieved from, information from within the call record itself, application of a rule, or input from the agent. The dialing mode may be altered under certain conditions. When the call is originated, various compliance oriented tests, including calling windows and call attempts, are performed.

  • Patent number: 9866622
    Abstract: Methods, apparatus, and computer-accessible storage media for remotely managing a gateway that serves as an interface between processes on a customer network and a service provider, for example to store data to a remote data store. The gateway sends a connection request to a gateway control server. The server holds the connection until the server receives information (e.g., information from the customer sent via the service provider) for the gateway. The server sends the information as requests via the gateway-initiated connection, and continues to hold the connection. If a server receives information for a gateway to which it does not hold a connection, the server sends the information to the server that does hold the connection. The server may either discover the appropriate server via a registration service that registers connections to gateways or broadcast the information to peer servers identified through a registration service.

A second memory stores requestee event records describing events that occurred in relation to processes executed in a second server in response to execution requests issued from the first server. An associating unit searches the first and second memories for requester event records and requestee event records whose transaction identifiers are identical and associates the found records together. A determining unit compares the associated event records with each other in terms of their time information. Based on this comparison, the determining unit determines a correction value for correcting time differences between requester event records in the first memory and requestee event records in the second memory.

  • Patent number: 9026468
    Abstract: Systems and methods for proactively establishing a third-party payment account for services rendered to a resident of a controlled-environment facility (“CEF”). A campaign-triggering event is detected, which triggers contact of prospective third-party (“3rd-party”) payers for a resident of a CEF in order to encourage such prospective 3rd-party payers to establish 3rd-party payment accounts for the resident. In this manner, the prospective 3rd-party payers are proactively contacted prior to an expected future demand for service by the resident. A method thus comprises identifying at least one prospective third-party payer for a resident of a controlled-environment facility, and proactively contacting the identified at least one prospective third-party payer prior to demand for service by the resident to encourage the identified at least one prospective third-party payer to establish a third-party payment account for payment for future service expected for the resident.

    Abstract: A call saving system for an ISDN telephone switching system includes a subscriber switching unit and terminal units connected to the subscriber switching unit via subscriber lines. A control device controls an overall call saving process executed between the subscriber switching unit and each terminal unit when a restart process is started after a call process is temporarily stopped. When a restart process is started, a restart message is transmitted to each terminal units on the basis of the presence/absence of a call to be saved. Each terminal unit includes a call state setting circuit for a state display message when information indicating a confirmation of a call saving is set in the restart message.

  • Patent number: 5452295
    Abstract: In a call disconnection method and a system for executing the same in an ATM (Asynchronous Transfer Mode) network, a plurality of timers are provided corresponding to each call in an exchange of an ATM network. A connected call is detected, and a data cell is not transmitted for longer than a predetermined time, by using the corresponding timer, and disconnecting the detected call from the ATM network.

  • Patent number: 4748657
    Abstract: A handset actuated signal intercept circuit is located in a telephone central office and connected to the tip and ring leads of a telephone subscriber line. The signal intercept is operated from central office subscriber line power, but draws so small a current that it is undetectable in normal telephone usage. When a subscriber handset is lifted, the signal intercept detects dial tone and initiates a timing interval of predetermined duration. If no dialing pulses or tones are detected during this interval, the central office channel and trunk which are seized by the initiation of dial tone, are then freed for use on other subscriber lines.

  • Patent number: 4645880
    Abstract: A disconnect circuit for use between two switching systems. An optical coupler monitors open and closed current loop conditions and provides signals representative thereof. Monostable multivibrators are operated in response to these signals to provide timing signals of predetermined durations. A relay circuit is controlled by these timing signals and it operates to disconnect the loop between the switching systems for a predetermined time.
