Making Calls

3.7 Last Number Redial

The Last Number Redial (LNR) feature automatically dials the last
number dialed from your telephone; LNR retains 16 digits for each
extension. You may either choose a specific outside line by first
pressing that outside line button, or you may allow the system to auto-
matically select the line.
To choose an outside line first, press an outside line button. Then
press Func + 8.
To let the system choose the outside line, simply press Func + 8.

3.8 Creating Conference Calls

The system can accommodate eight, four-member (party) conferences
simultaneously. Conferences can include a maximum of three outside
lines, and any number of extensions, to a maximum of four con-
ference members. One inside key telephone station is the controller
of the conference and constitutes one conference member. Before a
conference can be established with four members, a three-member
conference must be established first.
A Supervised Conference is a conference in which at least one
member is an extension of the DX-80 system. The DX-80 extension
that establishes a conference is the conference controller, and may
add and/or delete members of the conference at any time. The con-
ference controller also has the privilege of establishing an Unsuper-
vised Conference.
An Unsupervised Conference is a conference in which only callers on
outside lines are members. All members are therefore outside of the
premises and connected together using the DX-80 conference
resource. An unsupervised conference may be re-joined by the initi-
ating DX-80 extension, however, that extension maintains control of
the conference even though it is unsupervised.
To establish a three-party conference, perform the following steps.
