Rollover Extensions – Advanced Topics
Any number of extensions can be con
fi
gured to be a Rollover Extension. These extensions have
special properties. Generally, calls directed to extensions which are busy or do not answer will
be directed to an available Rollover Extension. Typically, extensions connected to a Voice Mail
unit or to an answering machine would be designated as Rollover Extensions though it is possible
to con
fi
gure any extension to be a Rollover Extension. It is also possible to assign an Exclusive
Answering Machine to an extension. When the IPS wants to ring an available Rollover Extension
(due to the conditions listed below), it will
fi
rst check to see if there is an Exclusive Answering
Machine available for the extension.
The IPS will ring an available Rollover Extension or Exclusive Answering Machine when:
• An incoming call has been ringing for greater than a specify amount of time (5 to 60 seconds).
See “Rollover On Standard Incoming Calls Timing”, page 98.
• The MSG button on a key telephone is pressed (if Voice Mail is enabled).
• An intercom call was attempted to an extension which is in the Do Not Disturb mode (if
Rollover on Intercom Calls is set), see “Rollover of Intercom Calls”, page 71.
• An intercom call was attempted to an extension connected to an ordinary phone which is busy
(if Rollover on Intercom Calls is set).
• An intercom call was attempted to an extension connected to a busy key telephone or to any
phone which does not answer within
fi
ve rings (if Rollover on Intercom Calls is set).
• An outside line has been blind transferred to an extension which does not answer or parked at
an extension which does not answer (provided the “Transfer to operator / Rollover Extension”
parameter speci
fi
cs Rollover Extension).
• After the operator is rung and does not answer after a call left on hold for too long rings at the
Operator, see “Rollover On Standard Incoming Calls Timing”, page 98.
When the IPS is looking for a Rollover Extension, it checks the extensions in the order of physical
extension #00 to extension #15 to
fi
nd an extension which is both available and designated to be
a Rollover Extension.
Exclusive Answering Machine Privilege
The Rollover Extensions feature allows you to specify which extension(s) will be rung when a
call is directed to an extension which is busy or does not answer. More than one extension can
be speci
fi
ed as a Rollover Extension so that a multi-channel Voice Mail unit can be attached to
the IPS.
In some installations, it may be desirable to give separate answering machines to certain people to
allow messages intended for them to be stored and retrieved independently. This may now be done
as part of the “Programming the Extensions” command (see “Programming The Extensions”,
page 32).
