Call Park
Feature Availability
This feature is available with all Generic 3 releases.
Description
Allows users to put a call on hold and then retrieve the call from any other voice 
terminal within the system.
When a voice terminal user, active on a call, needs to go to another location for 
information, the call can be placed in Call Park and retrieved at the other 
location.
Conference calls can also be placed in Call Park.
Call Park can be activated by any of the following:
nA single-line voice terminal user — Flash the  switchhook, dial the Call 
Park access code, and hang up.  The call is parked on the user’s 
extension number.
nA multiappearance voice terminal user — Press  the Transfer  or 
Conference b utton, d ial the Call Park a ccess code, and press the Transfer 
or Conference button again, or simply press the Call Park button (if 
assigned). The call is p arked  on the user’s extension number.
nAn attendant — Press Start, dial the Call Park access code followed by 
any extension number, and press Release.  The call is parked on the 
number dialed. An attendant can use the Direct Extension Selection With 
Busy Lamp  Field  feature instead of dialing the extension number. 
nThe system — When Code Calling Access is used, the call is 
automatically parked on the paged party’s extension numb er.
Calls are retrieved by dialing the Call Park Answer Back access code and the 
extension number where the call is p arked or, by pressing the same Call Park 
button used to park the call.
A system-wide expiration interval can be set for p arked calls.  When the interval 
expires, the parked call redirects to an attendant console (or, if administered, to 
the parking user) and no longer is parked on the extension number. However, if 
the parked call has already been retrieved when this interval expires, the call 
does not  redirect. If two parties are connected on a p arked  call, a third  party can 
also answer the call before the interval expires, creating a three-way conference. 
This option is tied to the default paging option. Timed out parked calls redirect to 
the attendant if the default ‘‘Loudspeaker Paging’’ option is assigned  and to the 
parking user if ‘‘Deluxe Paging and Call Park Timeout to Originator’’ option is 
assigned.

3-408Issue  3   March 1996 
If no attendant (this includes CAS, local attendants, and Individual Attendant 
Access) or night service extension is a dministered, and if Night Service 
— Trunk 
Answer From any Station is not administered, the expiration interval is ignored 
and the call remains parked.
The attendant console group can have common shared extensions numbers 
used exclusively for Call Park. These extension numbers are not assigned to a 
voice terminal, b ut are stored in system translations and used to p ark a call. 
These extension numbers are particularly useful when one party is paged at the 
request of another p arty. The calling party is  parked and the extension number is 
announced. The lamp  associated with the extension number identifies call 
parked or no call parked (instead of active or idle status).
Considerations
Call Park can be used whenever a voice terminal user who is on a call needs to 
go elsewhere and obtain information, and wishes to complete the call at another 
extension.  Call Park also allows users to answer a call from any station after 
being paged by a voice terminal user or an attendant.
Only one call per extension number can be parked at a time, even if the 
extension number has multiple appearances.  However, a conference call with 
five parties can be parked.  The sixth conferee is the retrieving party.
Calls cannot be parked on a g roup extension number. If a group memb er p laces 
a call in Call Park, the call is p arked on the member extension number. Group 
members include the following:
nA Coverage Answer Group member
nA DDC group member
nA TEG member
nA UCD group member
Interactions
nAbbreviated Dialing
An Ab breviated Dialing button can be assigned so that parking calls or 
retrieving parked calls c an b e done by pressing a button, instead of using 
the buttons and access codes normally used. This operation reduces the 
number of steps required to park a call or retrieve parked calls.
nAutomatic Wakeup
Automatic Wakeup calls cannot be parked.
nBrid ged Call Ap pearance 
						

							Call Park
Issue  3   March 1996
3-409
If a user, active on a bridged c all appearance, activates Call Park, the c all 
is parked on the primary extension associated with the brid g ed call 
appearance.
nCall Vectoring 
A call cannot be parked on a VDN extension. Also, a call that is 
undergoing vector processing cannot be parked.
nData Privacy and  Data Restriction
These features are automatically deactivated when a call is parked.
nLoudspeaker Paging Access
Calls to paging zones cannot be parked.
nLoudspeaker Paging Access — Deluxe 
If the system is a dministered to have Deluxe Paging, parked calls are 
redirected to the  parking user when the Call Park timeout interval expires.
nMusic-on-Hold
If a parked call involves only one p arty, the parked user hears 
music-on-hold.
— With a Call Park feature access code
— By pressing the Transfer button, the Call Park button, and Transfer 
button again
If a call involves only one party but was parked by pressing the 
Conference button, the Call Park button, and then the Conference button 
again, the parked user hears music-on-hold.
If a call involves multiple p arties (such as a conference call), none of the 
parties hears music-on-hold.
If Music-on-Hold is provided, the user activating Call Park also hears 
music after the call is parked and confirmation tone is heard.
nRemote Access
A Remote  Access caller cannot p ark a call.  However, the Code Calling 
Access feature, an answering attendant, or a voice terminal user can park 
an incoming Remote Access call.
Administration
Call Park is administered on a per-system basis by the System Manager. The 
following items require administration:
nCall Park access code
nAnswer Back access code
nCall Park Time-out interval (from one to 90 minutes) 
						

							Feature Descriptions
3-410Issue  3   March 1996 
nCall Park button (multiapp earance voice terminals only).  A Call Park 
button should have a lamp so that the voice terminal user can tell when a 
call is parked on his or her extension.
nCommon shared extension numbers for the attendant group.
nThe “Deluxe Paging and Call Park Timeout to Originator” field on the 
Feature Related System Parameters form must be a dministered as ‘‘yes’’ 
to have parked calls return to the parking user (the originator) when the 
Call Park Timeout interval exp ires. If this field is administered as ‘‘no’’ 
parked calls go to the attendant when the Call Park Time-out interval 
expires.
Hardware and Software Requirements
No a d ditional hardware or software is required. 
						

							Call Pickup
Issue  3   March 1996
3-411
Call Pickup
Feature Availability
This feature is available with all Generic 3 releases.
Description
Allows voice terminal users to answer calls to other extension numb ers within the 
user’s specified Call Pickup group.
Call Pickup groups are esta blished so that when one memb er of a g roup is away, 
other members of the group can answer that member’s calls. A Call Pickup 
group usually consists of users who are located in the same area or have similar 
functions.
When a memb er of a Call Pickup group is away and receives an incoming call, 
any memb er of the Call Pickup group can answer the call. A member simply 
goes off-hook and dials the Call Pickup access code or presses a Call Pickup 
button. That group member is then connected to the calling party.
A Temp orary Bridged Ap pearance is maintained at the called voice terminal. 
This allows the called party to bridge onto the call after it has been p i cked up by 
another memb er of the Call Pickup group.
If a Call Pickup group member’s voice terminal is e quipped with a Call Pickup 
button and status lamp, then:
— The status lamp has a steady light when Call Pickup is used to answer a 
call.
— The status lamp has a flash feature light when the ‘‘Call Pickup Alerting’’ 
option on the ‘‘System Parameters Feature’’ form is enabled and there is 
an incoming call to any extension in the Call Pickup group, including the 
called station. Group members, other than the principal called station, c an 
answer such calls using Call Pickup; the principal can answer such calls 
on the ringing call or bridged appearance.
NOTE:
Call Pickup Alerting for a voice terminal only takes effect when the 
Call Pickup status lamp is not lit. If Call Pickup is used to answer a 
call, the status lamp  displays a steady light and does not flash if 
there are additional calls to this Call Pickup group.
For the called station only, b oth the Call Pickup and the Call 
Ap pearance status buttons flash. 
						

							Feature Descriptions
3-412Issue  3   March 1996 
If calls are ringing at two or more voice terminals in a Call Pickup group, 
and another group member presses his or her Call Pickup button, then a 
distribution algorithm determines which call is answered. In this way, 
equal treatment is given to all Call Pic kup group members. Specifically, 
when a voice terminal’s Call Pickup button is pressed, the algorithm 
‘‘cycles’’ through the group extension numbers until it finds an extension 
with a call eligible for Call Pickup. The next time a Call Pickup button is 
pressed, the algorithm resumes cycling from the 
next extension number.
For examp le, if extension A has two calls ringing and extension B has one 
call ringing, and if one of extension A’s calls is answered using Call 
Pickup, then extension B’s call is answered the next time Call Pickup is 
activated. After extension B’s call is answered, Call Pickup can be used to 
answer the second call to extension A.
When multiple calls are ringing on a single voice terminal, and another 
member of the Call Pickup group activates Call Pickup, then:
nAll switches (exc ept G3i-Global), the call associated with the lowest 
call appearance number is answered. For example, if calls are 
ringing on the second  and fourth call appearance button on a voice 
terminal, and a user at another voice terminal activates Call Pickup, 
then the call on the second call appearance button is answered.
nFor G3i-Global, the call type and call appearance number 
determine which call is answered. The  precedence order for call 
types is:
1. Priority Calls
2. Attendant or Trunk Calls
3. Intercom Calls
4. All other calls
If multi ple c alls of the same c all type are eligible for Call Pickup, the 
call associated with the lowest call ap p earance number is 
answered. For exam ple, if priority calls are ringing on the second 
and fourth call appearance b utton on a voice terminal, and a user 
at another voice terminal activates Call Pickup, then the call on the 
second call appearance button is answered.
Considerations
With Call Pickup, a user does not have to leave his or her voice terminal to 
answer a c all at a nearby voice terminal. Instead, the user simply lifts the handset 
and dials an access code or presses a Call Pickup button. This allows 
unanswered calls to b e handled quickly and efficiently.
A voice terminal can be a member of only one Call Pickup group. 
						

							Call Pickup
Issue  3   March 1996
3-413
Setting the Call Pickup Alerting o ption on the ‘‘System Parameters Features’’ form 
to yes provides voice terminals equip ped with a Call Pickup button and status 
lamp with a visual notification that an incoming call is eligible for Call Pickup. 
Specifically, the voice terminal Call Pickup status lamp flashes when a call to 
another extension is available for Call Pickup.
NOTE:
Call Pickup Alerting for a voice terminal only takes effect when the Call 
Pickup status lamp is not lit. If Call Pickup is used to answer a call, the 
status lamp displays a steady light and does not flash if there are a d ditional 
calls to this Call Pickup group.
When a member of a Call Pickup group is away from his or her voice terminal and 
receives an incoming call, the other members of the Call Pickup group voice 
terminals do not ring. As a result, the Call Pickup feature is only useful if either:
— The Call Pickup Alerting option is enabled and the Call Pickup group 
members have voice terminals equipped with a Call Pickup button and 
status lamp.
— The memb ers of a Call Pickup group are located close to one another and 
can hear each other’s voice terminal ring.
Interactions
The following features interact with the Call Pickup feature.
nAutomatic Callback and Ringback Queuing
Callback calls cannot be answered by Call Pickup group members.
nBridged Call Appearance
The interaction between Call Pickup and Bridged Call Ap p earance 
d e pends on whether the Call Pickup Alerting option on the ‘‘System 
Parameters Features’’ form is enabled:
— If the Call Pickup Alerting option is set to ‘‘yes,’’ activating Call 
Pickup, while a bridged  call appearance  is ringing on a Call 
Pickup group member’s station, does not pickup the call.
For exam ple, if A drian’s voice terminal receives ringing on a call to 
a bridged extension numb er that is not in Adrian’s Call Picku p 
group, then the incoming call cannot be picked up by members of 
Adrian’s Call Pickup group.
— If the Call Pickup Alerting option is set to ‘‘no,’’ and if a voice 
terminal receives ringing on a brid ged call appearance, then the 
incoming call can b e picked up by members of that voice terminal’s 
Call Pickup group.
nCall Waiting Termination
A Call Waiting call cannot be picked up by a Call Pickup group member. 
						

							Feature Descriptions
3-414Issue  3   March 1996 
nConference
If Call Pickup Alerting is enabled and a call is picked up  and conferenced 
into a conference call, the Call Pickup status lamp flashes if a d ditional 
calls are available for Call Pickup.
nHold
A call, picked up and placed on hold at an extension, remains on that 
extension, even if the called party answers the call.
If Call Pickup Alerting is enabled and a call is picked up and placed on 
hold, the Call Pic kup status lamp flashes if a d ditional calls are available for 
Call Pickup.
nHot Line Service and Manual Originating Line Service
Voice terminals assigned these features can be Call Pickup group 
members so their incoming calls can be answered. However, voice 
terminal users with these features assigned cannot answer calls for other 
group members.
nIntercom—Automatic
Call Pickup can be used to answer an Automatic Intercom call.
nInternal Automatic Answer (IAA)
Internal calls to a voice terminal in a Call Picku p group are eligible for IAA. 
If the called extension in a Call Pickup group is IAA-active, the call is 
answered automatically. An extension that is IAA-active is not able to 
automatically answer calls to other voice terminals in its Call Pickup g roup. 
IAA-eligible calls to an IAA-active extension can’t be answered by Call 
Pickup (b ecause they are automatically answered at the called station), 
but any non-IAA-eligible calls such as external calls that ring the 
IAA-active station can be answered by members of that station’s call 
pickup group.
nTransfer
If Call Pickup Alerting is enabled and a call is picked up and transferred, 
the Call Pickup status lamp flashes if a dditional calls are available for
Call Pickup.
Administration
Call Pickup is administered by the System Manager. The following items require 
administration:
nCall Pickup group number
nMembers (extension numbers) of each Call Pickup group
nCall Pickup access code
nCall Pickup buttons

Call Prompting
Feature Availability
This optional feature is available with all Generic 3 releases except G3vs/G3s 
ABP.
Description
Uses s pecialized vector c ommands to provide flexible handling of incoming calls 
based on information collected from the calling party.
Call Promp ting  can be used in various a p plications to achieve better and more 
flexible handling of incoming calls. This description desc ribes four call p rompting 
applications. A brief description of each of the four samp le ap p lications is given 
below.  (A more detailed description of each ap plication is given later in this 
chapter.)
nAutomated Attendant — Allows the calling party to enter the extension of 
the party that he/she would like to reach.  The call is then route d to that 
desired extension.
nData In/Voice Answer (DIVA) Capability — Allows the calling party to hear 
an announcement b ased on the digits that he or she enters, or to be 
directed to a hunt group or another system extension.
nData Collection — Allows the calling party to enter data which can then 
be used b y a host/a djunct to assist in call handling.  This data, for 
example, may be the calling party’s account number.
nMessage Collection — Gives the calling party the option of leaving a 
message or waiting in queue for an agent.
Since the Call Vectoring feature is used with the Call Prompting feature, it is 
recommended that the Call Vectoring feature be read and understood in order to 
more easily comprehend this Call Promp ting feature description. Call Vectoring 
Basic is not a prerequisite for vector p rompting. This means that stand-alone c all 
prompting implementations cannot queue calls, or do any conditional checks 
based on queue or agent status, time of day, or day of week.
As in the Call Vectoring feature, VDNs are used to access Call Promp ting 
vectors. Each  VDN routes to a single Call Prompting vector but several VDNs 
may route to the same Call Prompting vector.
Call Prompting Vector Commands
The following list shows the complete set of vector commands that are used with 
the Call Prompting feature.
