Address properties can be altered in the property administration section of the administration application. Address properties that can be altered are curam.address.nondefaultaddressallowed and curam.address.addressDataLocaleForDefaultAddresses. The first property allows administrators to alter whether a user is allowed to enter an address in a format other than the system default layout. For example, If a user is recording a communication; a user can only enter a participant's address that differs from the default layout if this property is enabled. The second property enables the locale for an address to be set for which no details are provided. In effect, this allows a user to enter a place holder instead of an address if an address is not provided. This allows the user to enter an address at a later stage when one becomes available.
