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 reconnected for a
“Display Caller ID” programming change to take affect.

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 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
first check to see if there is an Exclusive Answering Machine available
for the ext ension.
The IPS will ring an available Rollover Extension or Exclusive
Answering Machine when:
¨ An incoming call has been ringing for greater than a specified
amount of time (5 to 60 seconds).  See “Rollover on Standard
Incoming Calls Timing”, page 92.
¨ The MSG button on a key phone 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 58.
¨ 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 phone or to any phone which does not answer within five 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
specifies 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 92.

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 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” comma nd (see “Programming the
Extensions”, page 11).
When an extension is enabled to have the Exclusive Answering Machine
privilege, the next numerical extension will be used as the Answering
Machine extension.  For example, if physical extension #05 is enabled
for this feature, calls directed to extension #05 will ring at extension #06
if extension #05 is busy or does not answer.  If extension #06 (the
answering machine) also happened to be busy, the IPS would look for an
available Rollover Extension.  Please note that calls may not be
for warded from the answering machine extension (in this case extension
#06) to a different extension.
In order to use this feature, the System Manager must correctly assign
the extensions such that a person’s answering machine is assigned to be
the extension immediately after that person’s phone extension.
Some answering machines will not respond to an incoming ring if the
length of the ringing signal is too short.  Ther efor e, it is advisable to set
the distinctive ringing feature for the answering machine extension to
have the IPS give the longest possible ringing signal.  This can be done
by attaching a single-line telephone to the answering machine extension
and dialing “4711” at the IPS dial tone.

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 busy, (3) an extension which
does not answer after 20 seconds, or (4) an extension connected to a key
phone which is busy and does not answer the intercom call within 20
seconds.
For unanswered Intercom calls to transfer to a Rollover Extension:
For unanswered Intercom calls to continue ringing at the dialed
extension:
7803

In the programming mode, lift the handset
and enter “7803”.  Pause for confirmation
tone.
7802

In the programming mode, lift the handset
and enter “7802”.  Pause for confirmation
tone.

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),
¨ incoming DISA calls directed to a busy extension, and
¨ incoming DISA calls directed to an extension which does not
answer.
To transfer unattached calls to an available Rollover Extension:
To transfer unattached calls to the Operator:
7804

At the System Manager’s extension, lift the
handset and enter “7804”.  Pause for
confirmation tone.
7805

At the System Manager’s extension, lift the
handset and enter “7805”.  Pause for
confirmation tone.

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 interpreted as a call to the voice mail
unit.
To enable operation with the Voice Mail unit:
To disable operation with the Voice Mail unit:
7824

At the System Manager’s extension, lift the
handset and enter “7824”.  Pause for
confirmation tone.
7825

At the System Manager’s extension, lift the
handset and enter “7825”.  Pause for
confirmation tone. 
						

							Page 61
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 mail and message
storage devices.  These devices typically accept only a single digit to
direct the caller into one of the limited number of internal mailboxes.  If
“Voice Mail Unit Interface” is enabled and “Simplified Voice Mail
Interface” is also enabled, the IPS will send only a single digit to the
Rollover Extension.  This digit will be the last digit in the extension’s
physical number.  Thus, a call intended for extension ‘104’ would cause
a ‘4’ digit to be sent to the Rollover Extension.  A call intended for
extension ‘100’ would cause a ‘0’ digit to be sent to the Rollover
Extension.  A call intended for extension ‘110’ would also cause a ‘0’
digit to be sent to the Rollover Extension.
REMEMBER:  Voice Mail must be enabled (“7824”) for this command
to cause a single digit to be sent to the Rollover Extension.
To enable operation in the Simplified Voice Mail mode:
To enable operation in the Standard Voice Mail mode:
7862

At the System Manager’s extension, lift the
handset and enter “7862”.  Pause for
confirmation tone.
7863

At the System Manager’s extension, lift the
handset and enter “7863”.  Pause for
confirmation tone.

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 prefixes) each time a call is placed.
It scans the table as each digit is entered.  If a match with the Disallow
Table is found, the call is denied.  If no match is found, the call is
permitted. Most commonly, a Disallow Table will include the prefixes
“1” (long-distance calls) and “011” (overseas calls).
Exceptions to the Disallow Table are needed to allow users to call “1-
800” numbers when all other numbers beginning with “1” are barred.  In
this case, you will need to create an Allow Table and enter the “1-800”
prefix.  Similarly, you can enter any other “exceptions” to numbers
barred such as out of town suppliers or clients.  Because the system
searches the Allow Table(s) first, the Disallow Table will not bar the call.
Creating toll restrictions requires two steps. First you will need to create
one or more Disallow and Allow Tables.  Then you will need to assign
individual extensions to the appropriate table(s).
The system can store up to three call barring Allow Tables and three
Disallow Tables. For most offices, one Disallow Table, or one per call
group, is sufficient. But if you want to have a wide variety of restriction
options, you can use up to three Disallow Tables and three Allow Tables.

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 extension
were to dial another digit, the unit would normally examine the complete
sequence of digits dialed and determine that the extension is not allowed
to make the call.  The extension would be disconnected from the outside
line.  A special provision has been made to the operation of the IPS such
that it will not check the call barring restrictions on a transferred call
unless and until the extension flashes in order to place the call on hold or
transfer the call.  This allows the caller to enter additional digits (perhaps
to a remote voice mail unit) without getting disconnected from the
outside line.
A second special case can arise if the outside lines are configured to
allow a switchhook (flash) to be sent to the outside line.  A switchhook
to an outside line may be needed to affect certain features like Call
Waiting.  However, some Central Office switches may give a new dial
tone in response to the switchhook.  In this case, the caller could possibly
dial an allowed number, send the switchhook, and then dial a restricted
nu mb er.  The IPS is only able to exa mine t he digits dialed starting at the
beginning of the sequence and the call would not be barred.  If this is a
concern, you may want to prohibit the switchhook from being sent to an
outside line (see “Programming Outside Lines”, page 30).
