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.
