Abstract: A system for diagnosing a session initiation protocol (SIP) trunk configuration may include one or more processors coupled to memory. The one or more processors may be collectively operable to execute a diagnostics environment. The diagnostics environment may include an interface module operable to access data associated with a configuration including a set of configuration settings assignable to a SIP trunk. The set of configurations settings may be associated with respective layers and/or sublayers of a network connectivity model. A comparison module may be operable to determine a configuration status of one or more of the layers and/or sublayers associated with the SIP trunk. A display module may be operable to cause the configuration status to be displayed in a user interface. A method of diagnosing a SIP trunk configuration is also disclosed.

Abstract: 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. For each of the phone numbers, the computing device is configured to detect call activity involving the phone number during a detection period having a preselected duration, determine an answer seizure ratio (ASR) for the phone number during the detection period from the call activity, determine a difference between the ASR during the detection period and an ASR from at least one previous detection period for the phone number, and determine whether the difference satisfies at least one preselected criterion. When the criterion is satisfied, the computing device instigates a procedure to investigate or repair the phone number.
