Abstract: Techniques for managing anomalies in a software system include monitoring the software system for anomalies via a plurality of signals and determining that signal results associated with the signals indicate a presence of an anomaly in the software system. The techniques also include identifying a hierarchy of sensors associated with the anomaly, where the hierarchy includes a parent sensor and a set of child sensors that are direct or indirect descendants of the parent sensor. The techniques additionally include executing the parent and child sensors to analyze the software system for one or more causes of the anomaly, and determining the cause(s) of the anomaly based on sensor results generated by the parent and child sensors. Finally, the techniques include causing remediation of the cause(s) of the anomaly based on one or more child sensors associated with the cause(s) and one or more resolutions mapped to the child sensor(s).

Abstract: A method for selecting a vocoder type for origination of a mobile telephone call including sending a first access request that includes a first value representing one of a set of vocoder types including a first vocoder type and a second vocoder type. If the first access request is rejected, then a second access request is sent. The second access request includes a second value representing one of the set of vocoder types other than the one of the set of vocoder types included in the first access request.
