    1297 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

    1298 Call Park 
    20
    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.

    Features and technical reference 
    1300 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.

    Features and technical reference 
    1301 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.

    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.
