abandoned call

A call that has been presented to an agent, but the remote party disconnected before speaking with the agent. For an inbound call, it may be that the called party got tired of waiting in queue. For an outbound call, it may be that the predictive or automated dialer reached a live contact and had the call available for presentation to an agent, but no agent was available to accept the call.

Note that FCC uses the term "abandoned" to refer to predictive calls that are answered by customers and not connected to agents within a compliance time (2 seconds). To avoid ambiguity, in Bright Pattern Contact Center, such calls are referred to as unattended calls.

access number

A telephone number of a contact center that can be accessed from the public telephone network. External access numbers are typically used as access points in dial-in scenario entries; however, some of these numbers can be instead associated directly with specific extensions to provide a DID function for those extensions.

access point

A point where the processing of service interaction attempts is initiated. For calls, an access point is usually either an access number or an extension dedicated to the automated processing of calls. For chats, an access point is usually a web page from which chat requests are initiated. The logical entity that defines the processing of interactions arriving at a specific access point is called a scenario entry.


See automated call distribution.


See After Call Work.

After Call Work

After Call Work (ACW) is an agent state indicating that the agent is unavailable to accept service interactions because the agent is currently processing information related to an interaction that the agent previously handled. This state is assigned from the moment the interaction is terminated and until the agent exits After Call Work either manually or by a system timeout.


A user providing contact center services to customers. An agent is usually one party in a service interaction, and the other party is a customer.

agent capacity

An agent's capability to handle more than one interaction at a time, by either filling gaps in text conversations, such as chat or SMS, or by overriding one interaction with another, such as by interrupting email processing with an incoming voice call.

Agent Capacity Model

In a multimedia contact center, an Agent Capacity Model is a method to determine an agent’s availability to handle an interaction that takes into account how much capacity is occupied by a single interaction of each media type, how much spare capacity the agents must have to be delivered an interaction of any given media type, and the relative priority of media types.

agent state

A real-time condition of an agent that determines the agent's availability to handle service interactions. For states that indicate unavailability, the agent state also provides a specific reason.


See Automatic Number Identification.


See average speed of answer.

automated call distribution

Automated call distribution (ACD) is a technology to improve customer satisfaction and maximize agent utilization by introducing fair automatic agent selection and a short wait time for incoming calls. Bright Pattern includes this functionality in omnichannel blended ACD.

Automatic Number Identification

Automatic Number Identification (ANI) is a telephone company service providing a calling party with a number of the calling party. It is often used instead of “calling party number.”

audio treatment

A prerecorded audio message that the system plays to the listener in a specific situation (e.g., while a call is waiting in queue or on hold).

automatic campaign

Also known as an IVR campaign, a type of campaign where the system automatically dials numbers from the associated calling lists, monitors call progress, and connects successful (answered) call attempts to a prerecorded IVR message. Agents are not involved in campaigns of this type.

auxiliary skill

A skill that is not directly associated with any configured services but may be necessary for a complete description of a service request. For example, a customer may request a service in a specific language. In this case, in addition to the default service skill, a language skill is defined and assigned to the agents who can provide the requested service in this language.

average speed of answer

Average speed of answer (ASA) is the key performance indicator of inbound call center performance. It reflects the average time a customer has to wait in queue until the call is answered. ASA is usually measured against a target metric value. (See also service level.) One of the ways to maintain target ASA is with correctly predicted staffing. Calculate staffing online at the specific average speed of answer with the Contact Center Calculator.


beep tone

A tone that plays periodically during a call to remind the parties that the call is being recorded. It may also be used as an alert to an agent that a call is about to be presented.

An agent state indicating that the agent is unavailable to accept service interactions because the agent is currently handling one or more service interactions (e.g., a call or a maximum number of chats). For inbound service interactions, this state is assigned from the moment the interaction is accepted and until it is terminated or transferred. For outbound service interactions, it is assigned when the interaction is initiated (i.e., for calls, it includes the dialing phase).

calling list

A list that contains destination data for campaigns. One list can be used in many different campaigns. Each list record typically contains information about a single customer and includes the customer’s name, at least one telephone number, and other information specific to the campaign purpose. For example, lists used in a satisfaction survey campaign may include information about products purchased by the customers.

call progress analysis

Call progress analysis (CPA) is the process of automatic detection of the result of a call attempt via analysis of the audio signals during call setup. CPA is used in predictive outbound calling campaigns.

call recording

A telephone conversation recorded and stored in a digital audio file format. Call recordings are used for quality management (QM) and compliance purposes.


A type of service where the contact center proactively initiates interactions with customers for a specific reason, such as for surveys or telemarketing, using destination data in the associated calling list(s).

Capacity Model

See Agent Capacity Model.


An instance of customer service that is created to track all communications related to a specific customer issue (e.g., request, order, complaint, problem, etc.) and is maintained while the issue is being worked on, and is closed when it is resolved. In general, a case may involve multiple communications via different media channels. In Bright Pattern Contact Center version 3.7 and later, cases are used to track email communications only. (See also email thread.)

An interaction via electronic mail. An inbound email interaction includes an original email sent from a customer to a business and the first meaningful response. (Auto-acknowledgment is not considered a meaningful response.) Any subsequent follow-up email sent by the agent is considered an outbound email interaction within the same email thread. Any subsequent email with the same subject sent by the customer is considered a new inbound email interaction within the same email thread.

See Text-to-Speech.


unattended call

A call attempt made within a predictive campaign that is answered by a customer but cannot be connected to an agent within a compliance time (2 seconds in the United States). Some countries regulate the percentage of unattended calls and/or what happens to a call when it is unattended. Note that FCC refers to such calls as "abandoned." In Bright Pattern Contact Center, the term abandoned is used to refer to calls that are terminated by customers before they are answered by agents.

unavailable time

A measurement of the time that an agent is not able to engage with contacts due to scheduled breaks, meals, After Call Work, or other activities.


A person who may need access to any functionality of Bright Pattern Contact Center for any reason. Usually this includes all contact center agents and supervisors, as well as all contact center managers, administrators, and scenario developers who may need to use Bright Pattern Contact Center user-facing applications to perform their tasks. The exact set of functionality available to a particular user within any application is defined by the role(s) assigned to this user in the system configuration.

voice callback

A contact center feature that offers calling customers an option of requesting a callback instead of staying online while waiting for an agent response. The decision can be made based on the current estimated wait time in queue. If the Callback option is selected, the original inbound call will be disconnected while the position of this call in the service queue is preserved. The callback is made when it is the caller’s “turn” to be routed to an agent.
