Avaya Aura® Messaging Release 6.2 supports both application-based and site-based dial plans.
If you have a multi-server Messaging system and you are using site based dial rules, you can configure the dial rules to be based on your site, which will allow you to perform dial rules tests from within the storage server. Hence, you will not have to go back and forth between the storage and an application server in order to run tests.
Future releases of Messaging will only support site-based dial plans. Therefore, customers must manually re-configure Messaging systems of earlier releases for site-based dial plans.
