13.1.2 What You Need to Know
The following terms and concepts may help you as you read through the chapter.
Authority Groups and Extensions
Basically, you can think of an authority group as a set of extensions. You use an
authority group to assign equal rights to the entire set of extensions. Thus, an
authority group is a group of extensions that all have the same authority. For
example, if you create two authority groups, you can allow one group to make
local calls and long distance calls and the second authority group to make local
calls only.
Authority Group Guidelines
Authority groups and extensions follow these guidelines:
• You must create at least one authority group on the X6004.
• Each extension can be a member of only one authority group.
• SIP, FXS and ISDN BRI extensions are treated the same within an authority
group.
Mobile Extensions
A mobile extension is essentially call forwarding to both your IP phone extension
and another phone. When you set up a mobile extension and then activate it from
your IP phone using a feature code (
), all calls sent to
your IP phone extension are also sent at the same time to the phone that is
designated as your mobile extension. When the call is picked up on one phone,
the X6004 stops ringing the other.
