Executive Busy Override — CO Line
Description
Allows a digital proprietary telephone user to barge into an existing outside call either between
2 outside parties on the ISDN line through the system or between an outside and an inside
parties, so as to establish a three-party conference call. It is possible for extension users to
prevent this function from being executed by another extension user (Executive Busy Override
Deny).
Conditions
• Class of Service programming determines the extension users who can perform Executive
Busy Override.
• The pre-assigned extension users can barge in any CO line even if access to the line is not
allowed by System Programming.
• This feature does not work if the extension has set Executive Busy Override Deny or Data
Line Security.
• When a two-party call is changed to a three-party call and vice versa, a confirmation tone
is sent to all 3 parties. This tone can be eliminated by System Programming.
