[Book] PBX Systems for IP Telephony
I saw a book in NCNU library: "PBX Systems for IP Telephony", written by Allan Sulkin in 2002.
(TK5105.8865 S949 2002) Its Appendix A lists some call processing features, such as
Station User Features
Add-on Conference
This feature allows a station user to add a third party to an existing two-party conversation.
Automatic Callback
This feature is used when a dialed station is busy. When the feature is activated, the system automatically attempts to callt he desired station until the line is free. The calling party is alerted that the called party is available. This saves wasted time dialing when encountering busy signals.
Automatic Intercom
This feature provides a talking path between two voice terminal users. A station user presses a programmed automatic intercom button and lifts the handset, or vice versa. The called user receives a unique intercom alerting signal, and the status lamp associated with the dial or automatic intercom button, if provided, flashes
Bridged Call Appearance
This feature allows the same line appearance to be programmed to appear on more than one telephone. It is very useful in manager-assistant relationships and call answering position environments. A bridged call appearance can reduce the number of abandoned or lost calls and allows the coverage station to prescreen calls for the called party.
Call-Back Last Internal Caller
This feature allows a station user to automatically consult and call back the last internal caller to the station (unanswered call) by implemententing the feature code.
Call Forwarding - All Calls/No Answer/Busy
This feature allows a station user to divert all incoming calls to another programmed station. All Call activation diverts all incoming calls to the station; no answer activation diverts calls after a programmed number of rings; busy activation diverts incoming calls when the station is busy. The features are useful when a station user is away from the desk area, wishes to receive calls at another station, or when there is a desire not to receive calls, but the user wants the call answered. The most common coverage station is a voice messaging port. Call forwarding features decrease abandoned or lost calls and improve call coverage service for the calling party.
Call Forwarding - Follow Me
This feature allows a station user to activate the call forwarding feature from a remote telephone by chainging an existing forwarding destination. It provides station users with the capability of changing call forwarding destinations without returning to their desks, and can be used to "follow" station users around the system if they wish to receive calls at different stations.
Call Forwarding - Off Premises
This feature allows a station to forward all calls to an off-premises location outside the system. It allows station users to receive calls at a programmed outside telephone line when they are out of the office.
Call Forwarding - Ringing
This feature allows a station user of a multiple line voice terminal with display to forward an incoming call during the ringing period to another station. The station user can read the display for screening information, such as CLID or calling party name, before activating the feature through a programmed feature button or dial access code. The rerouted call destination is input by the station user after feature activation. The operation is transparent to the calling party.
Call Forwarding - Selective Multiple Line
This feature allows a station user of a multiple line voice terminal to selectively call forward any or all line appearance numbers.
Call Hold
This feature allows a station user to place an existing call in a hold state when there is another incoming call or the station user must leave the desktop area for more than a few seconds. Call hold provides station users with the flexibility of handling multiple concurrent calls without re-establishing the connection after finishing another call.
Call Park
This feature allows a station user to "park" a call at the received station, effectively placing the call in a hold state, retrieve the call at another station, and contnue the conversation. A second party can also retrieve the parked call if notified by the first party. The feature provides station users with mobility and eliminates the need to return calls.
Call Pickup
This feature allows a station user to retrieve and answer a call directed to another station (direct), any station in the station user's assigned call pickup group (group), or another call pickup group (designated group). The station user presses a programmed call pickup button or dials the desired feature access code to implement the feature.
Call Transfer
This feature allows a station user to divert an existing call to another station within the system. It eliminates the need for the original calling party to hang up and redial another telephone line to reach the desired or proper called party.
Call Waiting
This feature notifies a station user engaged in conversation that there is another incoming call to the station line number. The notification is usually a special tone or display signal on the telephone. Call waiting reduces lost calls, improves customer service, and reduces the number of calls forwarded to another station or messaging system.
Consecutive Speed Dialing
For speed dialing all station number digits are registered as the speed dial code. This feature allows a common set of partial station number digits to be registered as the speed dial code, and allows the station user to dial the remaining digits of each number to establish the call.
Consultation (Broker) Hold
This feature allows a station user to place one party on hold and confer with a third party on another line. This feature reduces call backs and improves customer service. Some systems allow the station user to toggle back and forth between two lines.
Customer Station Rearrangement
This feature allows station users to physically relocate their multiple line voice terminals internal to the system. When a station user moves between locations, the voice terminal station (number and COS) is logically transferred. This service is activated as follows: dialing the "moving" feature code followed by a personal code; the terminal is out of service; the terminal is disconnected, moved, and reconnedted int he new location; the terminal is reinitialized by dialing its extension number, followed by the personal code; the station rings immediately and when answered, the set is validated. The former and latter locations must support the same category of voice terminal.
Discrete Call Observing
This feature allows a supervisor to monitor a conversation between an assistant and a caller on a preselected line. While the supervisor is listening, the voice terminal microphone is off and the assistant is informed that the feature is activated by a notice on the voice terminal display. During monitoring, the supervisor can take over the call.
Distinctive Ringing
This feature allows the system administrator to define distinct ringing patterns for different call types, such as internal, defined internal line, external, private network, emergency, and private line. Station users can use this feature as a call screening device to decide which calls to answer and which are to be forwarded to a coverage station. The number of distinct patterns differs greatly between different system models.
Dial by Name
This feature allows a station user with a voice terminal equipped with an alphabetical keyboard to call an internal extension or external number by typing in a name using last name, first name, or initials. The directory database can be locally stored in the voice terminal or accessed from a centrally located database in the PBX system or application.
Do Not Distrub
This feature allows a voice terminal user to request that no calls, other than priority calls, terminate at a particular extension number until a specified time. At the specified time, the system automatically deactivates the feature and allows calls to terminate normally at the extension.
Elapsed Call Timer
This feature provides a display of the elapsed time when a multiple line voice terminal is connected to any trunk circuit.
Emergency Access to Attendant
This feature allows emergency calls to be placed to an attendant with special priority status. Calls can be placed automatically when the telephone is in an off-hook state or by dial access. The attendant received visual and audible feedback when the call is received. The feature is important for situations requiring immediate attendant access.
Executive Busy Override
This feature allows a station user to cut into an internal party's conversation. This feature decreases call backs, saves time reaching the called party, and decreases calls sent to coverage positions.
Executive Calling
This feature allows a station to be assigned VIP class status. The feature allows a VIP station to send a special ringing signal to a called station when idle and automatically send multiple tone bursts to that station when busy.
Excecutive Access Override
This feature allows a station user to connect a call to an internal extension that is in call forward or do not disturb mode. The service is authorized by COS level.
External Paging with Meet-Me
This feature allows a station user or attendant to dial a local paging equipment access code and connect both parties automatically after the paged party has answered the page and dials a special access code.
Facility Busy Indication
This feature provides multiple line telephone users with a visual indication of the busy or idle status of internal station numbers, trunk groups, hunt groups, or paging zones. Station users can monitor the activity of frequently called numbers with this feature, eliminating encountered busy signals.
Group Listening
This feature allows a station user of a multiple line voice terminal with an integrated speakerphone to place a call using the handset and activate the terminal's built-in speaker, to allow others to listen to the conversation while the station user continues talking through the handset.
Hands-free Dialing
This feature allows a station user of a voice terminal with a built-in speaker to dial and monitor a call without lifting the handset.
Hands-free Intercom
This feature allows a station user of a voice terminal with a built-in speaker to answer a voice call without lifting the handset. The incoming voice call is ehard over the speaker.
Help/Information Key
This feature provides a station user of a multiple line voice terminal with display immediate access to help menus for terminal programming and feature access procedures. Information is displayed by the system in user-friendly way. If a feature access code is changed, it will be displayed automatically in the feature menu. Service consultation shows all the relevant functions and their associated feature codes. This feature allows self-traning on the voice terminal and also reduces the need for paper labels on telephone features.
Hot Line
This feature automatically dials calls to preassigned internal stations, off-premises stations, or feature access codes when the handset is lifted. It eliminates the need to dial a number or access code, thereby simplifying and accelerating the process.
Incoming Call Display
This feature, available on telephones with display fields, provides visual notification to the station user of the calling party's station number or incoming trunk group name. The calling party's name may also be displayed with the station number. The feature is a screeening device to decide whether to answer or divert the call.
Individual Attendant Access
This feature allows users to access a specific attendant console. Each attendant console can be assigned an individual extension number.
Intercom Dial
This feature allows multiple line voice terminal users to gain quickly access to sleect other voice terminal users within an administratered group. Calling voice terminal users lift the handset, press the dial intercom button, and dial the one- or two-digit code assigned to the desired party. The called user received an alerting tone, and the status lamp associated with the Intercom button, if provided, flashes.
Last Number Redialed
This feature stores the last number dialed by the station user and allows the station user to automatically dial the number by using a programmed feature button or feature access code. It simplifies the calling process, reduces misdialed calls, and saves time.
Line Lockout
This feature removes single line voice terminal extension numbers from service when users fail to hang up after receiving dial tone signals, followed by intercept tone signals. The intervals for each tone signal are administrable.
Loudspeaker Paging Access
This feature provides station users or attendants dialing access to voice paging systems. This is useful for paging purposes regardless of the station user's location within the premises environment. It is often used with the call park feature.
Malicious Call Trace
This feature allows a station user to notify a predefined set of station positions that a malicious call is in process. The notified station users can then gather information and data about the call to identify the calling source. The feature is useful when a CLID or ANI is not displayed.
Manual Intercom
This feature allows a station user to call a manual intercom group member by pressing the manual intercom button. All member of a manual itnercom group share a common signaling path. When the manual itnercom button is rpesssed, a special tone burst is sent over the voice terminal speakers of all gropu members. When a group member answers, a speech path is established.
Manual Originating Line Service
This feature connects single line voice terminal users to the attendant automatically when the user lifts the handset. The attendant code is stored in an abbriviated dialing list. When the manual originating line service voice terminal user lifts the handset, the system automatically routes the call to the attendant using the hot line service feature.
Manual Signaling
This feature allows a voice terminal user to signal another voice terminal user. The receiving voice terminal user hears a short burst of tone. The signal is sent each time the button is pressed. If the receiving voice terminal is already being alerted with an incoming call, manual signaling is denied.
Message Waiting
This feature enables multiple line appearance voice terminal users, by pressing a designated button on their own terminals, to light the status lamp associated with the message waiting button at another multiple line apppearance voice terminal. Activating the feature causes the lamp to light on the originating and receiving voice terminals. Either terminal user can cause the lamp to go dark by pressing the button.
Multiparty Conferencing
This feature allows multiappearance voice terminal users to set up multiparty conferences (typically between four to eight station users) without attendant assistance.
Music on Hold
This feature provides music to a party that is on hold, waiting in a queue, parked, or on a trunk call that is being transferred. The music lets the waiting party know that the connection is still in effect. The system provides automatic access to the music source.
