  • Publication number: 20210409228
    Abstract: 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.

  • Patent number: 11115453
    Abstract: Features relating to communicating delay information and minimizing aggregate processing delays corresponding to content streams, e.g., audio and video streams, in a multi-media communication session while still achieving stream synchronization, are described. Some embodiments are well suited for systems where video and audio streams are transcoded by different entities. In some embodiments downstream entities, e.g., transcoder and/or receiving end device, are informed about the delay introduced to at least one stream by one or more upstream devices, e.g., a transcoder. The downstream entity synchronizes the received content streams by adding artificial latency as needed to the relevant one of the streams based on the received delay information thereby avoiding unnecessary introduction of artificial delays at every transcoding node in the path.
