What is the difference between user name, register name and display name?
Both user name and register name are defined by the server. A user name is used to
identify the account, while a register name matched with a password is used for
authentication if the server requires. Display name is the caller ID that will be displayed
on the callee’s LCD screen. Server configuration may override the local configuration.
