  • Patent number: 10341452
    Abstract: A conference management system, network, and method for enabling the management of teleconference resources across multiple telecommunications networks that serve multiple conference domains. A disclosed multi-domain conference manager (MDCM) subscribes to a network management platform and for one or more sets of entities. Each set defines a particular combination of i) communications service provider(s) (CSP) and ii) enterprise, in which the combination defines a particular scope of management. When a conference-related event occurs, such as a particular conference involving video endpoints being set up with a unified communications (UC) network, the MDCM can notify a CSP network that is within a same scope of management as the UC network, to report on related events as they occur. The MDCM can then coordinate the connection of resources associated with the multiple domains via a cascaded link between bridging resources that serve the different domains.

  • Patent number: 9185628
    Abstract: A method and system for providing a second line service (“SLS”) feature to a subscriber using a telecommunications device (“TD”) which includes receiving at a switch on the network of the subscriber's primary service provider a communication made up of a trigger and a directory number. When the communication is received at the primary service provider's switch, the switch parses the communication and detects the trigger. Once the switch has received the communication, the switch additionally transmits a query message to a SLS platform that manages the SLS feature. As a result of the switch's query message transmission, the switch receives a reply to the query message from the SLS platform. Based at least in part on the reply to the query message, the switch can route the communication such that the switch connects one or multiple voice channel circuit between the subscriber's TD and the terminating TD.

  • Patent number: 9001691
    Abstract: Apparatus, methods, and machine-readable articles of manufacture improve reliability and scalability of a messaging system. In some embodiments, the system's configuration data and subscriber information are stored in a central repository of a core node, and replicated to one or more non-core nodes. Data replication may be performed in real-time or near real-time, periodically, sporadically, or otherwise. Nodes may rely on the replicated data to provide the system's subscribers and outside callers with services that do not involve updating of configuration or subscriber data. In this way, the non-core nodes may continue to process calls when the core node is unavailable. For example, the non-core nodes can route calls to the appropriate subscribers without relying on the core. As another example, die non-core nodes can take messages from callers when the core node is unavailable. The messages may be queued for posting and delivery when the core node becomes available.

The connection state judgment section detects whether connection between a first device and a second device is normal or abnormal on the basis of a pattern of signals that are other than a transmission signal transmitted from the first device to the second device at normal time and are required for transmission of the transmission signal. The zero-level signal insertion section outputs the transmission signal output from the first device to a destination during a period of time when the connection state judgment section judges that the connection between the first and the second device is normal, and which outputs a zero-level signal to the destination during a period of time when the connection state judgment section judges that the connection between the first and the second device is abnormal.

  • Publication number: 20130022193
    Abstract: Methods and systems for determining call types are described herein. An intelligent node is configured to determine whether a call is a mobile-to-mobile call between subscribers of a telecommunication service provider based on a response to a request from the intelligent node. The intelligent node may further be configured to send a state request to an interconnecting network of the telecommunication service provider. A node of the interconnecting network determines whether a serving subscriber identifier is included in a routing database of that node. If the identifier is not included, the node responds with an error message. If the identifier is included, the node communicates with a relay function and responds to the request with a state received from the relay function. The intelligent node may also be configured to send an ENUM query and receive an identifier of the telecommunication service provider associated with the serving subscriber.

  • Patent number: 8233591
    Abstract: The present invention provides a technique for providing a forced hold service such as is used for an emergency services call, which is supported at least in part over a packet network. The forced hold service acts to effectively hold a connection for the call with a called party, even when the caller takes an action that would normally end a call, such as going on hook, pressing end, or the like. When the caller takes an action that would normally end the call, the forced hold service allows the caller to automatically reconnect to the emergency services provider over the held connection upon going offhook, pressing send, or the like. Alternatively, the emergency services provider can effectively re-engage the call wherein the caller is reconnected over the held connection upon going offhook, pressing send, or the like.

    Abstract: Systems, devices and methods for implementing a hold-call-back feature in a telecommunications network. A first connection is established between a call server and a first terminal via a packet-based network and a second connection is established between the call server and a second terminal via the packet-based network. The packet-based network comprises at least a segment of the telecommunications network. The call server then joins the first connection with the second connection to establish communication between the first terminal and the second terminal. In response to receiving a hold-call-back activation command from the first terminal via the packet-based network, the call server splits the first connection from the second connection, terminates the first connection and parks the second connection. The call server may then repeatedly prompt the second terminal for a call reestablishment command.
