Administrators can configure the Sonus SBC 1000/2000 to display pre-login and post-login messages to users. If one is configured, a pre-login message appears just above the login dialog, and a post-login message is presented as a dialog following successful login.
This message is presented to the user on the login screen
In the left navigation pane, go to Security > Login Messages > Pre-Login Message.
This message is presented to the user immediately following a successful login
In the left navigation pane, go to Security > Login Messages > Post-Login Message.
