IVT-16 key phones which are not given this privilege will still be able to
display the Caller ID information for any call which is transferred to the
key phone while the call is in progress.  After the key phone is no longer
connected to the outside line, the Caller ID information is lost from that
phone.  Be aware that this parameter setting is sent to the key phone only
when the key phone is first plugged in to the IPS system.  Thus, the key
phone should be unplugged from the system and then...

Rollover Extensions - Advanced Topics
Any number of extensions can be configur ed to be a Rollover Extension.
Thes e ext ens ions have sp ecial prop erties.  Generally, calls direct ed to
extensions which are busy or do not answer will be dir ected 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 configure any extension to
be a Rollover Extension.  It is also...

When the IPS is looking for a Rollover Extension, it checks the
extensions in the order of physical extension #00 to extension #15 to find
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 dir ected to an extension which is
busy or does not answer.  More than one extension can be specified as a
Rollover Extension so that a...

Rollover of Intercom Calls
You can specify when and how the Rollover Extensions are to be used.
In most installations, the Rollover Extensions are used to take outside
calls which are not answered by the desired extension.  If this parameter
is set, the IPS will also cause unanswered Intercom calls to be directed to
the Rollover Extensions.  This will occur if an Intercom call is made to
(1) an extension which is in the Do Not Disturb mode, (2) an extension
connected to an ordinary phone which is...

Rollover of Unattached Calls
Certain outside calls which are “forgotten” can be progra mmed to ring at
eit her the Op erator or an available Rollover Ext ens ion.  The t yp es of
calls affected by this setting are:
¨ blind transfers to an extension which does not answer within 5 to 50
seconds (see “Rollover After Call to Extension”, page 93),
¨ calls parked at a busy extension for too long (see “Reminder Feature
Timing”, page 89),

Voice Mail Unit Interface
A Voice Mail unit can be attached to the Rollover Extension(s) of your
IPS system.  It will have a voice announcement to enable callers to your
business to access employees and/or their voice mailboxes. Enabling this
parameter allows information to be sent from the IPS to the voice mail
unit to tell it the original extension dialed so that the voice mail unit can
play the appropriate outgoing message.  Also, this parameter allows the
MSG key from a key phone to be...

Simplified Voice Mail Interface
When the Voice Mail Unit Interface is enabled, the IPS will send DTMF
(touch tone) digits to the Rollover Extension to inform the voice mail
unit as to (1) the original extension dialed so that the voice mail unit can
play the appropriate outgoing message, or (2) the extension dialing
directly into the voice mail unit to retrieve their messages.
The Simplified Voice Mail Interface setting has been implemented to
allow the IPS to easily interface with simpler voice...

MSG Button on a Key Phone
If the System Manager has enabled the Voice Mail setting, a person at a
key phone can press the MSG key and make an intercom call directly
into a Rollover Extension.  If the key phone extension has Exclusive
Answering Machine privilege, pressing the MSG key causes an intercom
call to be made to the answering machine extension associated with the
extension.

Call Barring (Toll Restriction)
About Call Barring
The Call Barring (or Toll Restriction) feature lets you bar specific
extensions from calling certain types of phone numbers (or prefixes).
This feature is most commonly used to bar toll calls (e.g., long-distance,
international, and/or 1-900 number calls). If this is not a concern in your
office, there is no need to program this feature.
When Call Barring is operating, the system consults a Call Barring
Disallow Table of phone numbers (or...

Call Barring (Toll Restriction) Details
As an extension dials each digit, the IPS scans the complete sequence of
digits dialed to check if the extension is barred from dialing the
sequence.  If the extension is restricted from dialing the number, the
outside line is immediately released and the person at the extension will
hear the fast error tone.
A special case can arise if an outgoing call is ma de from an unrestricted
extension and then transferred to a restricted extension.  If the...
