DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 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
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1288 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.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1289 Call Pickup 20 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. Related topics nFeature Access Code (FAC) screen nFeature-Related System Parameters screen nStation screen (multiappearance phones) nConsole-Parameters screen 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.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 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.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 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.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1292 Call Pickup 20 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.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1293 Call Pickup 20 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.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1294 Call Waiting Termination 20 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.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1295 Call-by-Call Service Selection 20 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
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Features and technical reference 1296 Call-by-Call Service Selection 20 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.
