1287 Call Park 
20
Call Park
Call Park allows users to put a call on hold and then retrieve the call from any 
other telephone within the system.
You can set a system-wide expiration interval for parked calls. If a call is not 
answered within the interval, the parked call redirects to an attendant or to the user 
who activated Call Park (the parking user). Calls redirect to the attendant if the 
default “Loudspeaker Paging” option is assigned and to the parking user if the 
Deluxe Paging and Call Park Timeout to Originator option is assigned.
If no attendant or night service extension is administered, and if Night Service — 
Trunk Answer from Any Station is not administered, the expiration interval is 
ignored and the call remains parked.
If two parties are connected on a parked call, a third party can also answer the call 
before the interval expires, creating a 3-way conference.
The attendant console group can have common, shared extensions used 
exclusively for Call Park. These extensions are not assigned to a telephone, but are 
stored in system translations and used to park a call. The extensions are 
particularly useful when one party is paged at the request of another party. The 
caller is parked on a common shared extension and the extension is announced. 
The status lamp associated with the extension identifies “call parked” or “no call 
parked” (instead of active or idle status).
Call Park allows telephone users to answer a call at one extension, but complete 
the call at another extension. Call Park also allows users to answer a call at any 
telephone after being paged by a telephone user or an attendant.
Considerations
nOnly one call per extension can be parked at a time, even if the extension 
has multiple call appearances. Conference calls with up to five parties can 
be parked; the sixth position must remain open for the retrieving party.
nCalls cannot be parked on a group extension. If a group member places a 
call in Call Park, the call is parked on the member’s extension. Group 
members can belong to the following:
— A coverage answer group
— A DDC group 
— A terminating extension group
— A UCD group

nIf all appearances on a parked telephone are busy and no attendant or 
night-service extensions are configured when the call park timeout expires:
— A parked call is dropped if no coverage path is assigned
— A parked call is not dropped if a coverage path is assigned.
Interactions
nAbbreviated Dialing
This button allows users to park calls or retrieve parked calls by pressing a 
button, instead of using the buttons and access codes separately.
nAutomatic Wakeup
Automatic Wakeup calls cannot be parked.
nBridged Call Appearance
If a user, active on a bridged call appearance, activates Call Park, the call is 
parked on the primary extension associated with the bridged call 
appearance.
nCall Vectoring
A call cannot be parked on a VDN extension. Also, a call that is 
undergoing vector processing cannot be parked.
nCode Calling Access
When a paging party dials the Code Calling Access code and the paged 
user’s extension, the paging party is automatically parked on the paged 
party’s extension.
nCommon Shared Extensions
If an attendant parks a call on a shared extension and tenant partitioning is 
not active, then when the call park timeout occurs, the call returns to the 
attendant group.
If an attendant parks a call on a shared extension and tenant partitioning is 
active, then when call park timeout occurs, the call returns to the attendant 
who parked the call.
The setting of the Deluxe Paging and Call Park Timeout to Originator field 
of the Feature-Related System-Parameters screen does not effect this 
behavior.
nConference
Conference calls can be parked.
nData Privacy and Data Restriction
These features are automatically deactivated when a call is parked.

nDrop
If a digital-telephone user parks a call and then pushes the drop button, the 
call is unparked. If the parked call is from an internal digital-telephone 
user, pushing the drop button does not drop the call. The parking user must 
hang up to drop the call.
nLoudspeaker Paging Access
Calls to paging zones cannot be parked.
nMusic-on-Hold
If a parked call involves only one party, the parked user hears 
music-on-hold. The parking user also hears music after first parking the 
call and hearing confirmation tone.
nRemote Access
A Remote Access caller cannot park a call. However, the Code Calling 
Access feature, an answering attendant, or a telephone user can park an 
incoming Remote Access call.

Call Pickup
Call Pickup and Directed Call Pickup allow a telephone user to answer calls that 
alert at other extension numbers within the user’s specified call pickup group. 
Directed Call Pickup allows telephone users to pick up any call on the DEFINITY 
ECS system.
Call Pickup
Establish a call pickup group so that when one member of a group is away, other 
members can answer the absent member’s calls. A call pickup group usually 
consists of users who are located in the same area or who have similar functions.
To pick up another user’s call, a user goes off-hook and dials the Call Pickup 
access code or presses a Call Pickup button.

1290 Call Pickup 
20
If a user’s telephone has a Call Pickup button and status lamp, then:
nThe status lamp lights steadily when Call Pickup is used.
nIf Call Pickup Alerting is activated, members’ status lamps flash when a 
call comes in to any extension in the call pickup group. Group members 
other than the called party, can answer using Call Pickup. The called party 
can answer on the ringing call or bridged appearance.
NOTE:
Call Pickup Alerting for a telephone takes effect only when the Call 
Pickup status lamp is not lit. If Call Pickup is used to answer a call, 
the status lamp lights steadily and does not flash if there are 
additional calls to the call pickup group.
Both Call Pickup and Call Appearance status buttons flash at the 
called party’s telephone.
If calls ring at 2 or more telephones in a call pickup group and a group member 
presses the Call Pickup button, a distribution algorithm determines which call is 
answered. Thus, all call pickup group members are treated equally. Specifically, 
when a Call Pickup button is pressed, the system searches the group extension 
numbers until reaching an extension with a call eligible for Call Pickup. The next 
time a Call Pickup button is pressed, the system searches from the next extension 
number.
For example, if extension A has 2 calls ringing and extension B has 1 call ringing, 
and one of extension A’s calls is answered with Call Pickup, then extension B’s 
call is answered the next time Call Pickup is used. After extension B’s call is 
answered, a user can answer the second call to extension A.
When multiple calls ring on a telephone and a group member activates Call 
Pickup, the call with the lowest call-appearance number is answered. For 
example, if calls ring on the second and fourth call-appearance button on a 
telephone and a user at another telephone activates Call Pickup, the call on the 
second call-appearance button is answered.
Directed Call Pickup
Directed Call Pickup functions like Call Pickup, except for the following:
nA user can answer an alerting call at any telephone on the system — the 
alerting and answering telephones need not be members of the same call 
pickup group.
nYou grant users permission to have their calls answered or to answer 
others’ calls with Directed Call Pickup on a per-telephone basis on the 
Class of Restriction screen.

1291 Call Pickup 
20
Considerations
nA telephone can be a member of only one call pickup group.
nWhen a call pickup group member is away from his or her telephone and 
receives a call, other call pickup group members’ telephones do not ring. 
Therefore Call Pickup is only useful if either:
— Call Pickup Alerting is enabled and call pickup group members have 
telephones with Call Pickup buttons and status lamps.
— Call pickup group members are in close proximity and can hear each 
other’s telephones ring.
nExclusion is not supported for pickup calls.
Interactions
nAbbreviated Dialing
A user can store:
— The Directed Call Pickup FAC plus a telephone address in an 
Abbreviated Dial button
— The Directed Call Pickup FAC. (The user then dials each extension.)
nAttendant
Attendant can use Directed Call Pickup, but other users cannot use the 
feature to answer a call alerting at an attendant’s telephone.
nAutomatic Callback and Ringback Queuing
Neither call pickup group members or Directed Call Pickup users can 
answer Callback calls.
nBridged Call Appearance
— If Call Pickup Alerting is activated and a bridged call appearance 
rings on a call pickup group member’s telephone, other group 
members cannot pick up the call.
— If Call Pickup Alerting is not activated and a telephone rings on a 
bridged call appearance, group members can pick up the call.
— If Temporary Bridged Appearance on Call Pickup is enabled, a 
temporary-bridged appearance is maintained at the called telephone. 
This allows the called party to bridge onto the call after it has been 
picked up by another call pickup group member.
— Directed Call Pickup cannot be used to pick up a call alerting at a 
bridged call appearance.

nCall Coverage
You can use Directed Call Pickup to answer a redirected call alerting at a 
covering user’s telephone if there is a call-coverage temporary bridged 
appearance.
nCall Detail Recording
The extension number dialed by the caller is recorded as the dialed number 
in CDR.
nCall Forwarding
If Temporary Bridged Appearance on Call Pickup is enabled, a temporary 
bridged appearance is maintained if the forwarded-to telephone belongs to 
the same call pickup group as the forwarded-from telephone. If Temporary 
Bridged Appearance on Call Pickup is not enabled, a temporary bridged 
appearance is not maintained.
nCall Pickup Alerting
If a user who is a member of a ringing telephone’s pickup group uses the 
Direct Call Pickup to answer a call and the call is the only call ringing for 
any member of the pickup group, the Call Pickup Alerting lamp goes dark 
when the user picks up the call.
If a user who is not a member of a pickup group uses Direct Call Pickup to 
answer a call, then Call Pickup Alerting does not apply.
nCall Waiting Termination
You cannot use Call Pickup to pick up a Call Waiting call.
nConference
If the Call Pickup Alerting field is enabled and a call is picked up and 
conferenced into a conference call, the Call Pickup status lamp flashes if 
additional calls are available for Call Pickup.
nConsult
If the Temporary Bridged Appearance on Call Pickup field is not enabled, 
the consult call from the covering user appears as an idle-call appearance.
nExpert Agent Selection
EAS agents can use Directed Call Pickup to pick up a call or have their 
calls picked up. The agent’s COR overrides the COR of the telephone 
where the agent is logged in.
If both the telephone’s COR and the logged-in agent’s COR allow Directed 
Call Pickup, the user picking up the call can use either the telephone’s 
extension or the agent’s loginID.

nHold
If the Temporary Bridged Appearance on Call Pickup field is not enabled 
and a user puts a call answered with Directed Call Pickup on hold, the 
called party cannot answer the call because a temporary bridged 
appearance is maintained. If the Temporary Bridged Appearance on Call 
Pickup field is enabled, then:
— A call picked up and placed on hold at an extension remains on that 
extension, even if the called party answers the call.
— If the Call Pickup Alerting field is enabled and a call is picked up 
and placed on hold, the Call Pickup status lamp flashes if additional 
calls are available for Call Pickup.
nHot Line Service and Manual Originating Line Service
Telephones assigned these features can be members of a call pickup group 
and have calls picked up, but they cannot answer calls for other pickup 
group members.
nIntercom ¾ Automatic/Dial
If Call Pickup on Intercom Calls is activated, you can use Call Pickup and 
Directed Call Pickup to pick up Automatic Intercom calls. If it is not 
activated, Automatic Intercom calls cannot be picked up and the calls are 
not included in the call-pickup-alerting-count.
nInternal Automatic Answer
Internal calls to a telephone in a call pickup group are eligible for IAA. If 
the called extension in a call pickup group has IAA activated, the call is 
answered automatically. An extension that has IAA cannot automatically 
answer calls to other telephones in its call pickup group.
IAA-eligible calls to an IAA extension cannot be answered with Call 
Pickup because they are automatically answered at the called telephone. 
Any non-IAA-eligible calls, such as external calls that ring the IAA-active 
telephone, can be answered by members of that telephone’s call pickup 
group.
nMalicious Call Trace
You cannot use Directed Call Pickup to pick up an alerting MCT call at the 
MCT-Controller telephone.
nMultimedia Call Handling
Do not use Call Pickup or Directed Call Pickup with a Multimedia data 
endpoint. However, calls alerting at the voice component of a multimedia 
complex can be picked up with Call Pickup or Directed Call Pickup.

nPrivacy — Manual Exclusion
In the following case, the called party is not dropped when Privacy — 
Manual Exclusion is activated.
A call is made to Station A and Station B picks it up using Call Pickup. 
Station A bridges onto the call by going off-hook on its call appearance. 
Station B activates Privacy — Manual Exclusion.
nTenant Partitioning
Directed Call Pickup follows existing Tenant Partitioning. The feature does 
not function across tenant partitions unless specifically administered to 
do so.
nTerminating Extension
You cannot use Directed Call Pickup to pick up a call alerting at a TEG 
extension number.
nTransfer
If the Call Pickup Alerting field is enabled and a call is picked up and 
transferred, the Call Pickup status lamp flashes if additional calls are 
available for Call Pickup.
Call Waiting Termination
Call Waiting Termination notifies a user with a single-line telephone who is active 
on one call that a second call is waiting. Single-line telephone users can place a 
call on hold to answer a waiting call. After answering the waiting call, they can 
return to the held call or toggle back and forth between the two calls. A 
single-line, telephone user can connect to only one call at a time.
Generally, the single-line telephone user hears one quick burst of tone when a call 
from another telephone user is waiting, 2 quick bursts of tone when an 
attendant-handled or an outside call is waiting, and 3 quick bursts of tone when a 
Priority Call is waiting.
NOTE:
Special ring tones are not supported over Direct Inward Dialing (DID) 
facilities.
A priority call can wait for the telephone to become idle even if Call Waiting 
Termination is not activated. However, an attendant-handled call receives busy 
tone unless the Attendant Call Waiting Indication field is set to 
y.
You assign Call Waiting Termination on a per-telephone basis.

Considerations
nAn analog telephone user must place the active call on soft hold and dial 
the Answer Hold-Unhold feature access code to answer the waiting call.
nIf an analog single-line telephone has Call Waiting enabled and has 
initiated a conference call, Call Waiting is denied. For example, caller A 
(on an analog telephone) is talking to caller B, then flashes and is talking to 
caller C, and then flashes to conference B and C. Then, if caller D attempts 
to call caller A, Call Wait is denied.
Interactions
Call Waiting is denied when the following features are activated at the single-line 
telephone:
nAnother Call Waiting Call
nAutomatic Callback (to or from the telephone)
nData Privacy
nData Restriction
A Call Waiting call cannot be picked up by a Call Pickup group member or by 
directed call pick-up.
Call-by-Call Service Selection 
Call-by-Call Service Selection enables a single ISDN trunk group to carry calls to 
a variety of services. It does not require that each trunk group be dedicated to a 
specific service. It allows you to set up various voice and data services and 
features for a particular call.
Call-by-Call Service Selection provides the following benefits:
nCost reduction
 — Since many services share the same trunks, the total 
number of trunks can be reduced.
nImproved service
 — Features and services are less likely to be blocked.
nSimplified Networking
 — Network engineering is simplified because 
analysis of trunking needs can be done based on total traffic instead of on a 
per-service basis.
nTimely response to changes — With UAPs, the network does not have to be 
consulted.
nMeasurement of Call-by-Call Service Selection calls

Brief description
Call-by-Call Service Selection uses the same route patterns and route preferences 
that are used by Automatic Alternate Routing (AAR), Automatic Route Selection 
(ARS), and Generalize Route Selection (GRS). The service or facility used on an 
outgoing Call-by-Call Service Selection call is determined by information 
assigned in the AAR/ARS/GRS route patterns. 
You can allow a variety of services to use a single trunk group. The system obtains 
trunking efficiency by distributing traffic over all the available trunks. Then you 
can assign services that are used on incoming and outgoing Call-by-Call Service 
Selection calls. The system provides traffic measurements for each individual 
service administered for an ISDN Call-by-Call Service Selection trunk group.
A Call-by-Call Service Selection example is shown below.
