Abstract

Disclosed in some examples are methods, systems, and machine-readable mediums which provide for a communication monitoring system configured to automatically monitor and process communication records according to one or more error detection profiles to detect one or more error conditions described in the error detection profiles. The system may then automatically determine a network segment that is experiencing the error condition and acts to correct or avoid the error condition. For example, the system may instruct a conference communication service to re-route a caller over a different network segment, instruct a user's device to use a different network segment, send a message to a reporting computing device of the offending network segment, or the like.

Claims20

Dependent claims

A computing device for communication network troubleshooting, the computing device comprising:

a processor;
a memory, comprising instructions, which when executed by the processor, causes the processor to perform operations comprising:
identifying a plurality of communication records corresponding to a plurality of network communications sessions occurring within a first time window;
determining, using the plurality of communication records, a count of a number of network communications sessions having a duration within a particular duration range;
determining that the count of the number of network communications sessions within the duration range exceeds an expected number of communications by a threshold amount;
responsive to the count exceeding the expected number of communications by the threshold amount, identifying a first network path that carried at least one network communication session having the particular communication duration based upon the communication records;
and
causing a network configuration change to route a future network communications session over a second network path.
