Hunting
If Executive Intrusion is attempted against an extension with a Hunt DN
configured, an attempt will be made to reroute the call to the hunt DN
provided the Hunt DN is on the same node. If the Hunt DN is busy, this
rerouting process is repeated. If all DNs in the Hunt chain are busy, Executive
Intrusion is attempted against the wanted extension originally dialed.
Otherwise, the call will terminate as a simple call on the first idle extension
in the Hunt chain.
Integrated Services Digital Network (ISDN) Basic Rate Interface
(BRI) Extension
Activation of Executive Intrusion for an ISDN BRI extension is not possible.
Attempts to intrude on ISDN BRI extensions (either the requested or
unrequested party) will fail.
Intercept Computer (Dial from Directory)
Executive Intrusion can be activated by dialing an extension DN from the
Intercept Computer Terminal, and then pressing the BKI key on the Attendant
Console.
Line Lockout
Executive Intrusion is not allowed for any set that is in Line Lockout state.
Make Set Busy
Do Not Disturb
Executive Intrusion is not allowed if either of these features is active at the
requested party.
Multiple Appearance DN
If the attendant tries to extend a call to a DN which appears on more than one
set, this DN can either be:
— Multiple-Call Arrangement with Ringing (MCR): when a call terminates
on this DN, all idle stations on which the DN appears are rung. The call
is established only with the station which has answered first. All others
are idle.
— Multiple-Call Arrangement with No Ringing (MCN): the only difference
between MCN and MCR is that the called stations are not rung (only
their DN keys flash).
