Abstract:
1. A method to be executed at least in part in a computing device for determining alerts based on endpoint performance in a unified communication network (UCN), the method comprising: retrieving collected call metrics, the call metrics comprising network payload metrics and payload metrics, wherein the network payload metrics comprise a linear combination of a sum of network degraded calls, calls with a high delay due to the network, and failed calls, wherein the linear combination of the sum is divided by a total number of calls, wherein the payload metrics include a Listen Mean Opinion Score (LMOS) that is based on decoded audio received by an endpoint during a session, a Send Mean Opinion Score (SMOS) that is based on pre-encoded audio sent by an endpoint during a session, and a Conversation Mean Opinion Score (CMOS) that is based on a conversational clarity index for a remote endpoint, wherein the payload metrics are presented by a normal distribution with mean and standard deviation values of LMOS, CMOS, and SMOS; categorizing the retrieved metrics; comparing values of the categorized metrics to predefined thresholds such that each call associated with a categorized metric is classified; comparing a number of aggregated calls according to a selected class to an alert threshold; and if the alert threshold is exceeded generating an alert.
