A user-defined variable. User-defined variables may have any name provided the name begins with
user.. A user-defined variable converts to the type of the value assigned to it. For example, if a user-defined variable is assigned the value of the
calling-party-number.address variable, the user-defined variable effectively becomes a Text variable. A user-defined variable may be reassigned and thus converted from one variable type to another, for example from String to Integer, however type conversion is not recommended (for clarity reasons).
<var-name> portion of the variable name is case-sensitive. For example, the variable names
user.FOO refer to two different user-defined variables.
