An abandoned call is a call or other type of contact initiated to a call center that is ended before any conversation occurs. When inbound calls are abandoned, it is often because the caller is discouraged by the time on hold or a phone menu that is difficult to navigate.


A call center agent is a person who handles incoming or outgoing customer calls on behalf of an organization. A call center agent might handle account inquiries, customer complaints or support issues.

An agent who manages both incoming and outgoing customer calls is also referred to as a blended agent. Other names for call center agents include customer service representatives (CSRs), contact center agents, technical support representatives (TSRs), associates, operators, account executives or team members.

Agent Status

The agent status indicates how the team member is presently engaged and their current availability to handle another task. Team members in a call center might have the following statuses:

Available: An agent is available and able to take calls from their assigned queues. Busy: An agent is busy and unavailable to take calls. For example, an agent may be on break or working on a project. Learn how to create custom busy statuses. Offline: An agent is offline and not currently working. Assigned: An agent is assigned to a call but hasn't accepted it yet. On a call: An agent is currently on a call. Wrap-up: An agent has finished a call and is performing any duties needed before starting a new task. For example, an agent may be typing a call note or linking an article to the ticket. Listening: An agent is listening in on an active call.

Automatic Call Distribution (ACD)

Automatic call distribution systems are phone systems that automatically receive incoming calls and distribute them to the best available agent. ACDs help inbound contact centers sort and manage large volumes of calls to avoid overwhelming the staff. They also improve customer experiences by making sure calls are connected to capable agents as quickly as possible.

Automatic Speech Recognition (ASR)

Automatic speech recognition is technology that provides the ability for a person to interact with a computer application with their voice, thereby eliminating the need to input data using the keypad. For example, automatic speech recognition eliminates the need for callers to “press one” when they contact customer service. It does this by converting a person's words into something a system can use, such as text or a computer command.

In contact centers, Interactive voice response (IVR) systems use automatic speech recognition to enhance the customer experience. When integrated with other applications, ASR technology enables callers to perform self-service tasks, such as checking account balances, as well as authenticating their identity prior to speaking with an agent. Automatic speech recognition can also be useful for identifying why the customer is calling and using this information to route the call to the appropriate agent.
