Which SAT command is used to define the digit 8 as the AAR access code?

The command used to define the digit 8 as the Automatic Alternate Routing (AAR) access code is “change feature-access-code.” This command is specifically designed to configure feature access codes within the Avaya communication system, allowing administrators to set or modify how features are accessed through dial codes.

Establishing the AAR access code is crucial because it determines how users will initiate an AAR call. By defining the digit 8 as the access code, the system ensures that when users dial this digit, the system recognizes it as a request to use AAR for call routing, which can help manage outbound call traffic more efficiently and reduce the risk of call blocking.

The other commands mentioned are focused on different aspects of AAR configurations. For example, “change aar analysis” deals with how AAR analyzes the call and determines call routing based on defined criteria, while “change aar parameters” might modify overall AAR settings that affect its function but not the specific access code. The "add aar parameters" command is used to add new parameters to the AAR configuration, not to change an existing access code. Hence, the focus on modifying feature access codes makes “change feature-access-code” the appropriate choice for this scenario.
