Novel tools and techniques are provided for implementing fraud or distributed denial of service ('DDoS') protection for session initiation protocol (“SIP”)-based communication. In various embodiments, a computing system may receive, from a first router, first SIP data indicating a request to initiate a SIP-based media communication session between a calling party at a source address and a called party at a destination address. The computing system may analyze the received first SIP data to determine whether the received first SIP data comprises any abnormalities indicative of potential fraudulent or malicious actions. If so, the computing system may reroute the first SIP data to a security deep packet inspection (“DPI”) engine, which may perform a deep scan of the received first SIP data to identify any known fraudulent or malicious attack vectors contained within the received first SIP data. If so, the security DPI engine may initiate mitigation actions.

Fraud or distributed denial of service (DDoS) protection for session initiation protocol (SIP)-based communication

Novel tools and techniques are provided for implementing programmatical public switched telephone network ('PSTN') trunking for cloud hosted applications. In various embodiments, a computing system may determine one or more first network interconnection characteristics associated with a first entity service provider within a call service network operated by a call network service provider. Based on the determined one or more first network interconnection characteristics associated with the first entity service provider, the computing system may cause a network provisioning application layer to establish one or more network interconnections between a first network associated with the first entity service provider and the call service network, in some cases, by establishing shared peering connections between the first network and the call service network. The shared peering connections may enable a plurality of customers of the first entity service provider to establish call service connections that are shared over the shared peering connections.

Programmatical PSTN trunking for cloud hosted applications

Novel tools and techniques are provided for implementing management of routing across multiple voice or data networks with separate routing masters. In various embodiments, in response to receiving a request to establish a call between a calling party in a first network and a called party in a second network, a computing system might receive a first set of network information from a first routing database(s) that is operated by a first service provider and a second set of network information from a second routing database(s) that is operated by a second service provider separate from the first service provider; might analyze the received first and second sets of network information to generate a unified routing model for optimizing routing of the call through the first and second networks; and might establish the call through a selected optimized route based on the generated unified routing model.

Novel tools and techniques are provided for implementing monitoring and detection of fraudulent or unauthorized use in telephone conferencing systems or voice networks. In various embodiments, a computing system might monitor call activity through telephone conferencing system or voice network. In response to detecting use of the telephone conferencing system or voice network by at least one party based on the monitored call activity, the computing system might identify incoming and/or outgoing associated with a call initiated by the at least one party. The computing system might analyze the identified incoming and/or outgoing call data to determine whether the call initiated by the at least one party constitutes at least one of fraudulent use or unauthorized use of the telephone conferencing system or voice network. If so, the computing system might initiate one or more first actions.

Fraud or distributed denial of service (DDOS) protection for session initiation protocol (SIP)-based communication

Novel tools and techniques are provided for implementing originating number or address-based route determination and routing. In various embodiments, a computing system may receive, from a first router among a plurality of routers in a first network operated by a first service provider, first SIP data, the first SIP data indicating a request to initiate a SIP-based media communication session between a calling party at an originating address in an originating network and a called party at a terminating address in a terminating network. The computing system may determine a communication route among a plurality of routes through the plurality of routers in the first network for establishing the SIP-based media communication session, based at least in part on the originating address, and may establish the SIP-based media communication session between the calling party and the called party via the determined communication route.

Aspects of the present disclosure involve systems, methods, computer program products, and the like, for collaboration conferencing with multiple participants over a communications network, and more specifically for a conferencing controller in the network configured to control certain aspects of establishing a collaboration conference. In one particular embodiment, the user of the network may access the control system application to provide one or more conferencing parameters or settings the user wishes to be present during a collaboration conference session. The parameters may then be established by the control system and associated with the conferencing session involving the user. In one embodiment, such information may be associated with the identification token. In yet a further embodiment, a user to the collaboration control system may subscribe to receive a notification when another user of the system accesses a portion of a collaboration of the system.

Aspects of the present disclosure involve systems, methods, computer program products, and the like, for balancing or routing a received communication on a telecommunications network among a plurality of network devices. More particularly, a load balancing unit is associated with a telecommunications network that receives communications from one or more network devices intended for transmission through that network and selects an associated component of the network to process the communication.

Load balancing of network communications

Aspects of the present disclosure involve systems, methods, computer program products, and the like, for collaboration conferencing with multiple participants over a communications network, and more specifically for a conferencing routing service for managing and routing collaboration participants. A collaboration conferencing routing server may provide configurability in routing a collaboration conference to a conference bridge based on any number of criteria and information about the requester and the communications network on which the conference occurs.

Method for routing in a central conferencing routing server

A differentiated routing system is provided for routing a communication service according to an access point of a subscriber terminal to a first network domain. The system includes a computing system executing a core routing engine (CRE) that receives a request for a communication service from the subscriber terminal. When the communication service is to be routed to a second network domain, the CRE identifies an access point at which the subscriber terminal accesses the first network domain, includes a tag in the request according to the identified access point. The tag includes information to be used by the second network domain for routing the communication service. The CRE then transmits the request to the second network domain.
