Browse terms A-Z

A	Definition
Abandonment Rate	Abandonment rate measures the percentage of callers who hang up before reaching an agent. High abandonment often points to long wait times, poor routing, or understaffed queues. Tracking it helps managers adjust staffing and improve caller experience.
After Call Work (ACW)	ACW is the time agents spend completing tasks after a call ends, such as tagging, writing notes, or sending follow ups. These steps keep records accurate and help the next agent understand customer history. Efficient ACW keeps agents available for more calls.
Agent Status	Agent status shows whether an agent is available, busy, on break, or doing ACW. The system uses this information to decide where calls should go. It also helps supervisors understand staffing levels.
Agent Status-Dependent Routing	Agent status dependent routing directs calls based on an agent’s current availability, such as available, busy, or in after call work. This ensures calls are only sent to agents who can answer them. It helps prevent missed calls and keeps queues moving efficiently.
Agent Utilization	Agent utilization measures how much of an agent’s paid time is spent on productive work. This can include handling calls, completing after call work, or managing customer messages. Tracking utilization helps managers balance productivity with agent workload.
Agent Occupancy	Agent occupancy measures the percentage of logged-in time agents spend handling customer interactions or related work. High occupancy can show strong productivity, but very high levels may lead to burnout. Managers use this metric to balance efficiency with sustainable workloads.
Agent Zoom	Agent zoom allows supervisors to focus on a specific agent’s activity in real time. It shows details like current call status, queue position, and recent performance metrics. This helps managers provide targeted support when needed.
Agentic AI	Agentic AI refers to AI systems that can plan, make decisions, and complete tasks with limited human input. In contact centers, it may handle workflows such as summarizing calls, updating records, or guiding follow-up actions. It helps teams automate multi-step work while keeping supervisors in control.
Answering Machine Detection (AMD)	Answering Machine Detection is a feature used in outbound calling to determine whether a call is answered by a human or an automated system. It analyzes audio patterns such as silence, speech length, and response timing at the start of the call. This helps outbound teams decide how the call should be handled and reduces unnecessary agent wait time.
Auto-Answer	Auto-answer automatically connects inbound calls to agents without manual acceptance. It reduces delays when agents are ready. This is often used in high-volume environments.

Automatic Caller ID	Automatic Caller ID selects an outbound caller ID based on the destination region. This helps display a local number to the recipient. It can improve answer rates.
Automatic Number Identification (ANI)	Automatic Number Identification captures the phone number of an incoming caller. Contact centers use ANI to identify callers, match them with customer records, or apply routing rules. It helps agents get context faster and supports accurate call tracking.
Average Handle Time (AHT)	AHT measures the average time an agent spends on a customer interaction, including talk time and ACW. It helps teams understand how much time is needed to resolve issues. Lower AHT is not always better, since some problems require more attention.
Average Speed of Answer (ASA)	ASA measures the average time it takes for a call to be answered by an agent. It is commonly used to evaluate queue performance. Lower ASA generally indicates faster response times.

B
Blended Contact Center	A blended contact center handles both inbound and outbound communication. This setup helps teams stay productive during slow periods by shifting between tasks. It also allows supervisors to balance workloads based on demand.
Blind Transfer	Blind transfer moves a call to another agent or destination without checking availability. The transferring agent does not stay on the call. This is useful for quick handoffs.
Business Process Outsourcing (BPO)	Business Process Outsourcing means hiring an external provider to manage business functions such as customer support, sales, or back-office work. In contact centers, BPO teams handle inbound and outbound interactions for clients across different markets, channels, and languages.
