FaxPlus Settings (User Extensions)
The FaxPlus tab contains settings for a given group of users (they all share the same group name) to specify a range of numbers, which can later be allocated to users, within the same group, by a FaxPlus administrator. The range is administrated within the UserExtensions tool.

The Services drop-down list specifies the service to be used for the range.
The range (specified in the "Range of valid fax extensions from/to" fields) can be any range of ascending numeric characters. When the range fields are left blank, the admin can specify any free address for the user and no limiting range is going to be used.
Please read the chapter "EXTENDED FEATURES – User Extensions" for more information.
To promote a normal FaxPlus user to a FaxPlus administrator, just check the "Enable administration of FaxPlus group members" box.
