A device receives call information associated with a call from a first user device to a second user device, where the first user device is associated with a first network, and the second user device is associated with a second network separate from the first network. The call information includes a caller identification and is received via an originating network device of the first network. The device determines whether the caller identification is verified, and adds authentication information to the call information when the caller identification is verified. The device receives the call information and the authentication information from a terminating network device of the first network, and removes the authentication information from the call information. The device adds a cryptographic signature to the call information, and causes the call information and the cryptographic signature to be provided to the second network for routing to the second user device.

Validating and securing caller identification to prevent identity spoofing

The present invention relates to methods, systems, and apparatus for generating and/or using training data. An exemplary embodiment includes the steps of: generating from a first plurality of communications a first set of media fingerprints and corresponding communications information, the media fingerprints included in the first set of media fingerprints and corresponding communications information being a first set of media fingerprints; generating from a second plurality of communications a set of media fingerprints of a first type, each individual communication of the second plurality of communications having characteristics indicating a probability greater than a first threshold that the individual communication is of the first type; labeling individual media fingerprints in the first set of media fingerprints and corresponding communications information as being of the first type when the individual media fingerprint being labeled matches a media fingerprint in the set of media fingerprints of the first type.

Methods, systems and apparatus for generating and/or using communications training data

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.
