Is there a way to change the feature listed here
Improved Security for Accessing Cisco Unity
To enhance security, the Cisco Unity conversation no longer indicates whether the ID or password is invalid when subscribers log on by phone. Instead, when a subscriber enters an incorrect ID and/or password, Cisco Unity merely indicates that the subscriber entered an invalid combination, and then prompts the subscriber to re-enter both the ID and the password. In this way, it is not clear to an unauthorized user which part of the credentials is valid.
In addition, Cisco Unity no longer applies the prompt speed and volume that is specified for an individual subscriber until the subscriber enters both a valid ID and a valid password.
I would like to change this feature back to the way it was in Unity 4.0(5). When you actually where told that your id isn't valid if you don't have a valid Unity account.
Any help is appreciated
There's no option to do that - we were forced to change this along the way a while back because it's required by many state/fed/millitary installs - by telling the caller their ID is invalid you give "fishers" a very easy way to construct a table of valid user extensions in your system and then they can set about cracking PWs for them at their leisure. For most sites its an unacceptable security hole. There's no configuration option to force it back to the old conversation flow.
