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.
