Messaging offers two mailbox licenses: Mainstream and Basic. The Mainstream license is the full featured Messaging system that includes Reach Me, Notify Me, and speech-based addressing features, fax support, and IMAP access to the Avaya message store. The Basic license provides a subset of the Mainstream features. Administrators can combine Mainstream and Basic licenses system wide and also on individual locations.
Administrators control the features that are included in the mainstream license through Class of Service (CoS). A user in a CoS that includes one or more mainstream features requires a mainstream license. Licensing and CoS controls access to the features. User Preferences takes into account what features a user has access to and only displays options and settings for those feature that a user can use.
Removing a feature from a user CoS or moving a user to a CoS with fewer features affects the feature availability in two different ways, depending on whether the feature is actively enabled by the user or passively available to the user.
The Reach Me, Notify Me, and Fax features function even when these features are removed from a user CoS, as these features are actively enabled by users. However, the user cannot change the settings for these features in the User Preferences Web pages after these features are removed from a user CoS.
The IMAP access to Avaya message store and speech-based message addressing features are passively enabled for users in a CoS with these features. The user does not have control over these features. When these features are removed from a user CoS, these features immediately stop functioning.
