A computer-implemented method for authenticating a source of a telephone call to a recipient of the telephone call may include receiving, prior to receiving the telephone call, a request to input first authentication information. The first authentication information may include a passcode or a selection of a security question. The method may include receiving input of the first authentication information and sending, by the user device, the first authentication information to a computing device associated with the source of the telephone call. The method may include receiving the telephone call from the source and receiving input from the recipient of the telephone call to answer the telephone call. The method may include receiving second authentication information from the computing device, where the second authentication information may include the passcode or an answer to the security question. The method may include outputting the second authentication information.

An authentication server according to an embodiment disclosed includes a number receiver that receives a number of a user terminal from a callee who has received a call originated from the user terminal, an device authenticator that determines whether to generate an authentication key based on the number of the user terminal received from the callee and a caller number received from the user terminal, and generates the authentication key when it is determined to generate the authentication key, and an authentication key transmitter that transmits the authentication key to the user terminal.

A redirection and messaging system receives telephony information identifying a caller and call context from a telephony system. The system selects one of a plurality of messaging operators based on the call context, optionally sends an introductory message to the caller via a messaging service, and generates a message interface for the selected message operator. The message interface includes the caller and call context and any messages sent between the caller and the selected message operator, with an input interface allowing the selected message operator to input and send messages to the caller.

Automated message generation to a subject matter expert in response to a phone call is provided. A computing device receives a message identifying a telephone call that terminates at the computing device based on a destination number. Caller identification information, comprising at least a calling device number, is determined based on the message. An item identifier (ID) associated with the telephone call is determined. Information about an item that corresponds to the item ID is accessed. The information is sent to the calling device number. A message that includes the calling device number and item information that identifies the item is sent to a contact device.

Systems and methods for implementing an online content item campaign with selective call functionality can include a processor determining a rendering frequency of instances of a third-party content item for rendering with a call icon, based on a resource of the third-party content provider. The processor can provide a first instance of the content item for rendering with the call icon in accordance with the rendering frequency of instances. A call bridge device can receive a call from the client computing device upon actuation of the call icon, direct the call to a phone number of the third-party content provider, and determine a parameter of the call. The processor can adjust the rendering frequency of instances based on the parameter of the call and provide instances of the content item for display by client computing devices with the call icon in accordance with the adjusted rendering frequency of instances.

Call spoofing can be mitigated by providing geolocation information to the called device. For example, when a call rings, a geolocator can be invoked and the incoming call display screen can show a carrier logo and/or a geolocator globe illustrating the location of the call originator. The geolocation session initiation protocol data can be confirmed by a network device and compared against carrier specific data of the calling device to authenticate voice calls for called devices. In one embodiment location data of the calling device can purposely be shared in order to facilitate the mitigation of call spoofing.

A mechanism is provided for implementing an emergency response cognitive computing system. The emergency response cognitive computing system identifies a first party about which a communication is being performed between a caller and the emergency response system. The emergency response cognitive computing system generates, in real-time, a transcript of the communication as the communication is being conducted. The emergency response cognitive computing system performs natural language processing on the transcript of the communication to identify portions of content corresponding to medical concepts. The emergency response cognitive computing system processes patient information to identify elements of the patient information referencing concepts corresponding to medical concepts. The emergency response cognitive computing system outputs the elements of the patient information to a second party involved in the communication.
