A system for monitoring phone numbers includes a computing device having at least one processor and memory associated with the processor. A telephone network supports a plurality of telephone numbers. The computing device is configured to obtain data directly from the telephone network. The data indicates call activity involving the phone numbers, respectively, during a time period having a preselected duration. The computing device determines, for each of the phone numbers, whether the data indicates that there were no successfully answered calls placed to the phone number during the time period. For any such phone number, the computing device places a test call to the phone number. In the event that the test call is not successful, the computing device provides an indication of a problem with the phone number.

A denial of service (DoS) detection and circumvention system is described herein. The DoS detection and circumvention system can track phone calls that are initiated and store a list of phone numbers that are called. The DoS detection and circumvention system can also track the number of carrier congestion messages over a certain time window. Using the list of called phone numbers and the tracked number of carrier congestion messages, the DoS detection and circumvention system can identify excessive congestion. If the DoS detection and circumvention system identifies excessive congestion, the DoS detection and circumvention system can delay calls so as to prevent a possible DoS condition.

A system and method for monitoring telephone calls to detect call traffic pumping activity and take corrective action is described. The system receives a group of training telephone calls having associated call audio content and associated information, and the system analyzes the training telephone calls to generate and store a classification model that correlates call features and associations with a probability of call traffic pumping activity. The system receives a subsequent monitored telephone call to be analyzed. The system analyzes the monitored telephone call to identify features present in the audio content of the monitored telephone call and other associated information. The system then compares the features and associated information to the stored classification model in order to determine a probability that the monitored telephone call is associated with call traffic pumping activity. If the assessed probability of call traffic pumping activity exceeds a threshold, the system takes appropriate corrective action, such as terminating or flagging the monitored call.

Methods and systems for providing a rating system that allow for customers to create a database of toll-free numbers that are abused by malicious consumers which may be cloud-based and allow for service providers to dip prior to completing or accepting calls.

A system, method and non-transitory computer readable storage medium comprising instructions that when read by a processor perform receiving a telephony connection request at a location in a telephony network, the location separated from an intended recipient of the telephony connection request by a target telephony network, determining addressing information regarding the intended recipient, the addressing information including at least routing information or a phone number, determining a status characteristic of the intended recipient based on the addressing information, based on the status characteristic, and determining whether the intended recipient would successfully receive the telephony connection request if the telephony connection request was forwarded to the intended recipient.

Systems and methods are provided for generating application data from call data. In one implementation, a method includes acquiring call data from a call-data source with a call-data aggregator; modifying a portion of the call data with a call-data modifier; and generating application data from the portion of the call data. Application data may be configured for diagram generation. The diagram may graphically indicate call volume in branches of an interactive voice response (IVR) system map. The diagram may be a flow diagram including a connector associated with a branch of the IVR system map and the connector may have a width proportional to a call volume in the branch of the IVR system map. The diagram may indicate call-portion durations, which may be associated with a phase of a call and which may have a color associated with a phase of a call.

One or more embodiments related to a method of generating a graphical user interface. The method includes obtaining a metric interface hierarchy having multiple nodes, where each node defines a visualization for the node, and the metric interface hierarchy defines an ordering on the nodes. The method further includes traversing the metric interface hierarchy starting with a selected node to obtain a subhierarchy, and creating the graphical user interface from a general interface by populating the general interface with the visualization from each node in the subhierarchy according to the ordering. The method further includes providing the graphical user interface.
