Understanding Call Correlation

Message segments (call legs) of a call event can be distributed and stored on multiple mediation engines. Call correlation is the process of collecting all the distributed message segments of the call event from each mediation engine, merging them in the order of the call, and displaying the call event as a whole.

Mediation Engine Connector allows a user to monitor multiple mediation engines. Because each mediation engine contains its own list of call events, which may contain only call legs of the full call event, Mediation Engine Connector has to decide which of the call events from each mediation engine are from the same call. When passing a call event through a device monitored by multiple mediation engines, the Mediation Engine Controller locates any identical call events and consolidates the data. The consolidated call event data is displayed as one single call event flow in Mediation Engine Connector.

Note:

If any error is encountered while connecting to any of the Mediation Engine, a warning is displayed besides the Mediation Engine node selector drop-down so that the users can check the connection nodes in the Connection test settings option.
