摘要： One example involves a communications server providing communications services to remotely-situated client entities, wherein each client entity is associated with users and each user is associated with a communication device. The server may verify a first authentication factor for a user among the users, and generate a communication request that includes a first portion specifying at least one target endpoint associated with the user and a second portion associated with or indicating the security code and that includes a set of instructions which: are specific to the user, which specify how to communicate the security code for the user, and which specify different security codes for different types of communications. Via the server, the security code is sent to the user according to the set of instructions, and verified via a second authentication factor associated with or for the user by comparing input from the user to the security code.

摘要： In a telecommunication system comprising multiple switching nodes (10, 20, 30) having a respective local server (C1, C2, C3) and associated terminals (D1, D2, D3, D4) located within a network and a central DSS server (DSS) for controlling the telecommunication system by using a general switching protocol, the terminals (D1, D2, D3, D4) of a switching node (10, 20, 30) are controlled by the local server (C1, C2, C3) under a local protocol comprising control commands for node-internal call pickup. The pickup of a call directed from a third terminal (D4) to a first terminal (D3) assigned to a first switching node (10) through a second terminal (D1) assigned to another, second switching node (20) occurs across nodes by using the general switching protocol through transferring the control commands provided in the local protocol for call pickup to the general switching protocol and providing them across nodes through the central DSS server (DSS) to the multiple switching nodes (10, 20, 30) located within the network, and converting the registration of a terminal (D1, D2, D3, D4) for call pickup provided in the local protocol to the general switching protocol and forwarding it to the central DSS server.

摘要： Techniques are described for determining when and how to re-route toll-free calls around a core telephony network experiencing significant disruptions. A core telephony network of a telephony service provider is monitored for anomalies. Upon detecting an anomaly, it is determined whether the anomaly is significant enough to warrant re-routing inbound toll-free calls around the core telephony network. The re-routing process comprises accessing an industry registry database including a plurality of toll-free numbers (TFNs) associated with a routing template comprising the instructions for routing toll-free calls. The routing template instructions may be switched to re-direct toll-free calls associated with one or more specific TFNs to a particular carrier. Within that particular carrier, the routing instructions may be switched to re-direct the toll-free calls away from the service provider's core telephony network to a network bypass cloud platform. The network bypass cloud platform may be configured to receive toll-free calls, determine a customer telephony network to which to route the received toll-free calls based on the TFN of the toll-free call, and route the toll-free call to the customer telephony network.

摘要： Certain aspects of the disclosure are directed to template-based management of telecommunications services. According to a specific example, a server is provided comprising one or more computer processor circuits configured to interface with a remotely-situated client entity using a first programming language. The server includes a call control engine that is configured to provide a private branch exchange (PBX) for the client entity, and identify a call control template written in a second programming language. The call control engine is further configured to control call routing by the PBX, by executing the call control template to identify at least one data source that corresponds to a call property for the VoIP telephone call, retrieve data from the data source, and implement one or more call processing functions specified by the call control template as being conditional upon the retrieved data.

摘要： Certain aspects of the disclosure are directed to template-based configuration and management of telecommunications services. According to a specific example, a server is provided comprising one or more computer processor circuits configured to interface with a remotely-situated client entity using a first programming language. The server includes a provisioning circuit and a call control circuit. The provisioning circuit is configured to identify a provisioning template for at least one extension for a client entity, and configure the extension for one or more call processing functions. The call control circuit is configured identify at least one call control template written in a second programming language. The call control circuit is further configured to control call routing for VoIP telephone calls by executing the call control template, and to implement one or more call processing functions specified by the call control template as being conditional upon retrieved data.

摘要： The disclosure relates to a 5th generation (5G) or 6th generation (6G) communication system for supporting a higher data transmission rate. A method performed by a session management function (SMF) node in a wireless communication system is provided. The method includes receiving, from the user equipment (UE), a protocol data unit (PDU) session establishment request for establishing at least one PDU session between the UE and multiple internet protocol (IP) multimedia subsystem (IMS) networks, subscribing, with a unified data manager (UDM) node to receive a first notification for a proxy-call session control function (P-CSCF) restoration, by providing an identifier for each PDU session, receiving, from the UDM node, the first notification for the P-CSCF restoration based on a subscription with a UDM, and performing, the P-CSCF restoration for the PDU session of the UE based on the received first notification for the P-CSCF restoration.
