Abstract: Methods and apparatus for call traffic anomaly mitigation are described herein. One or more embodiments include receiving a scoring request including a telephone number associated with a telephone call at a scoring device from a call processing entity, receiving a violator list of telephone numbers and their corresponding severity values at the scoring device from an anomaly analyzer, determining a severity value associated with the telephone number by performing a lookup operation in the violator list, performing a random simulation using the severity value as a probability to determine an indicator value, and inputting the indicator value into a model to determine a call reputation score.

Abstract: Methods and apparatus related to the storage and/or recovery of session state information are described. A communications server, e.g., a web RTC server, supporting a communications session, stores session state information corresponding to the communications session in a client device, e.g., a user device including a web browser, participating in the communications session. Following a failure of the communications server, the client device establishes a new connection with a replacement communications server and communicates the stored session state information to the replacement communications server. In some embodiments, the session state information is communicated between a communications server and a client device in encrypted form via a secure HTTP web socket connection. In various embodiments, both the communications server and the replacement communications server include or have access to a shared encryption key.

Abstract: The present invention relates to methods and apparatus for handling maintenance events in Public Cloud Deployments with no or minimal service impact. An exemplary embodiment of implementing a communications service in a Public Cloud system comprises the steps of: (i) registering, by a Maintenance Management application of the communications service, to receive notifications for maintenance events scheduled for virtual machines and/or servers of the Public Cloud system being used to implement the communications service; (ii) receiving, by the Maintenance Management application, a maintenance notification indicating a first virtual machine is to undergo a maintenance event; (iii) determining, by the Maintenance Management application, public IP addresses being hosted by a first Packet Front End application executing on the first virtual machine; and notifying session control applications of the communications service to drain the determined public IP addresses being hosted by the first Packet Front End application.

Abstract: Communications methods and apparatus for preserving STIR/SHAKEN original attestation/signature information for diverted Session Initiation Protocol (SIP) messages and/or calls. An exemplary method embodiment includes the steps of: receiving, at a first Session Border Controller (SBC), a diverted Session Initiation Protocol (SIP) INVITE message corresponding to a first call, the diverted SIP INVITE message not including an Identity header; obtaining an original Identity header or information from the original Identity header corresponding to the first call using one or more of the following: information included in the diverted SIP INVITE message, information included in a Session Description Protocol message included in the diverted SIP INVITE message, an SBC trunk group, or a source Internet Protocol (IP) address transport protocol port of an IP packet carrying the diverted SIP Invite message; and generating an Identity header based on the original Identity header or information from the original identity header.

Abstract: Communications methods and apparatus for providing and/or adding STIR/SHAKEN Diversion Information to requests. An exemplary method embodiment includes the steps of: receiving at a second communications network a Session Initiation Protocol (SIP) Invite request from a first communications network, the SIP Invite request being directed to a first SIP address corresponding to a first user equipment device located within the second communications network, the SIP Invite request including a SIP Identity shaken header and one or more SIP Identity div headers; determining at the second communications network whether or not the received SIP Invite request was previously diverted by the second communications network to another network; and when the SIP Invite request is determined to have been previously diverted by the second communications network to another network, processing the SIP Invite request at the second communications network as a previously received and diverted SIP Invite request.

Abstract: The present invention relates to methods and apparatus for determining a best or optimal media path or route between communications devices. An exemplary method embodiment of the present invention includes the steps of (i) receiving, at a first communications device, data of a first data communications session, the first data communications session being a first media communications session, the data being media; (ii) selecting an optimal media communications route from a plurality of communications routes between the first communications device and a second communications device; and (iii) communicating the received media of the first media communications session from the first communications device to the second communications device via the selected optimal media communications route. In some embodiments, the optimal media communications route is determined by a UCBot application executing on the first communication device based on media quality metrics for each of the routes determined during test media sessions.
