An Avaya Aura® enterprise solution consists of a network of various applications, including Session Manager, Communication Manager, Experience Portal (Voice Portal), Messaging, and Voice Recording. Communication Manager, which is currently the most prominent application, consists of a server and all of the components under that server’s control. The various components can be placed into logical and/or physical groups.

A single Communication Manager system comprises one or more network regions. Each network region is a logical grouping of components such as endpoints, gateways, and certain circuit packs. The components of a Communication Manager system could also span various physical placements including gateways and geographical locations (sites).

Knowledge of the details of the configuration topology, from both logical and physical standpoints, is essential to properly conduct a traffic analysis. In particular, the topology often plays a role in determining the routes that are traversed by various call types.
