A computer-implemented method of for optimizing cellular network performance including identifying a plurality of voice call records stored on an application server in a first type of cellular network. The method includes analyzing call data associated with the plurality of voice call records, and identifying a set of fall back voice call records. The call data for each voice call record of the set of fall back voice call records includes a fall back indicator indicating that each voice call was initiated using a second type of cellular network. The method includes analyzing cause codes in the call data associated with the set of fall back voice call records and determining, based on the cause codes, a value for at least one KPI associated with the second type of cellular network.

A system and method of providing caller identification (ID) over a public switched telephone network (PSTN). For outbound calls, the system and method enable a caller to provide a caller ID that differs from the native caller ID of their mobile phone. The system and method enable multiple phones tied to a single account to display the same caller ID for outbound calls. For forwarded inbound calls, such as calls being forwarded from an office, the system and method inform the recipient of the identification of the call as well as that the call is being forwarded. The system and method enable the recipient to have calls forwarded from more than one number and identify the identity of the caller as well as the specific number the call is being forwarded from.

Systems and methods for automatically authenticating an incoming call are disclosed. In one implementation a method for automatically authenticating an incoming call includes receiving a call from a calling device. The call includes an identifier associated with the calling device. The method further includes receiving, separately from the call, authentication data associated with a device or a user, determining, using the identifier and the authentication data, that the authentication data is associated with the same calling device that initiated the call, verifying the authentication data, and based on a result of the verification, determining that the call is initiated by an authenticated device or user.

Disclosed is a work process supporting system based on interactive voice and text communication, and more particularly a work process supporting system based on interactive voice and text communication, in which at least one of a voice and a text is selectively applied according to congenital/acquired conditions of an information or service requester, so that a work process for providing information or service can be carried out, thereby freeing from constraints in input/output means for performing the work process for providing the information or the service and carrying out the work process while keeping continuity, reliability and accuracy.

A method, system, and computer program product for managing communication privacy in a conversation system are provided. The method detects an utterance on a public channel by a user of a computing device. A privacy nature of the utterance is determined. Based on the privacy nature, a classification confidence is determined for the utterance. The method generates a privacy question to be presented to the user based on the privacy nature and the classification confidence. In response to a confirmation response, a privacy channel is established. The method switches from the public channel to the privacy channel.

A computer-implemented network verification system includes a second device situated in a terminating call network and configured to receive a call signal from a first device situated in an originating network. The first device is coupled to a first registry that stores originating call records. The first registry is configured to obtain, from the first device, and store call data and a SIP identity header associated with the call signal. The system also includes a second registry coupled to the second device and configured to receive, from the first registry over an out-of-band verification network, a first verification request that contains the originating call record, including the SIP identity header associated with the call signal. The second registry is further configured to send the SIP identity header contained in the first verification request to the second device.

This Application describes mechanisms to provide priority levels for call connection requests and/or messages from a sending device to a receiving device. The receiving device is configured to allow prioritized notification alerts for incoming call connection requests and/or for incoming messages from a sending device to override a silent or do not disturb mode for one or more contacts based on i) a priority level provided with the call connection request or message and ii) a priority setting for the sending device or a set of devices associated with a user of the sending device.

A communicator device including a network interface for facilitating internet protocol (IP) communication, a public switched telephone network (PSTN) device interface for facilitating communication with a PSTN device and a processor. The processor is configured to communicate with a user application via an IP connection, receive instructions via the IP connection, generate a telephone ring signal based on the instructions, output the telephone ring signal to the PSTN device via the PSTN device interface, in response to the PSTN device providing a response to the telephone ring signal, establish a tip/ring connection between the PSTN device and the communicator device, and perform a data exchange between the user application and the PSTN device via a communication link that includes the IP connection and the tip/ring connection.
