Working in a call center

Before you get acquainted with the various call center terminologies, here is a quick look. In short, this is what it is like to work in a call center.

Traditionally, a call center is a centralized workplace that handles both incoming and outgoing calls. For example, anyone with a high school diploma can apply. As a result, the industry requires no specific college degree.

Many call centers also offer a competitive compensation package. In the Philippines, for example, it is among the highest-paying professions. In addition, call centers employ a large share of the working population.

Some companies prefer their call center in-house. However, many businesses opt to contract out this function to BPO providers locally or offshore to foreign call center BPOs.

Another benefit of this sector is flexibility. Because the work suits telecommuting, BPOs can transition to remote setups quickly when needed.

Why is there a need to know these call center terminologies?

As a call center agent, you must know these call center terminologies. After all, you will use them in your daily work. They are specialized words and expressions that belong specifically to the call center field.

Moreover, you will not hear these call center terminologies in everyday conversations. Instead, you will learn most of them during training. In addition, you pick them up on the floor during your work shift.

Understanding these call center terminologies also makes your job easier. For example, if you encounter the term “first-call-resolution,” you would immediately know what to do.

30 call center terminologies you must know

Now, let us dive into the list. Here are thirty call center terminologies to help you out.

1. Abandoned call

An abandoned call can happen on either inbound or outbound calls. For inbound call centers, it occurs when a customer starts a call and drops it before a conversation begins.

For outbound call centers, abandoned calls usually happen with a predictive dialer. For example, the dialer places a call that a customer picks up, but no agent is available to handle it.

2. Automatic Call Distributor (ACD)

ACD is a specialized phone system that handles incoming calls. Its main purpose is to identify a caller’s specific information. Then it transfers the call to the correct agent or department.

3. Average Handle Time (AHT)

AHT refers to the total average time a call center agent spends on every call. For example, this includes the conversation, hold time, and after-call activities.

You calculate average handle time using this formula: (overall conversation time + hold time + after-call related activities) / number of handled calls.

4. Basic Rate Interface (BRI)

A BRI, also known as Basic Rate Access (BRA), is one of the two basic configurations of Integrated Services Digital Network (ISDN). It has two bearer channels, one for voice and one for data. In addition, it has another channel for signaling.

5. Benchmarking

Benchmarking in a call center refers to a set of measurement standards. For example, companies use it to compare specific areas with other organizations. As a result, they can determine which areas need improvement. It also applies to Key Performance Indicators (KPIs).

6. Call Blending

Call blending is a method that organizes the flow of inbound and outbound calls. For example, if one representative handles more incoming calls than outbound calls, they will keep receiving more incoming calls.

As a result, call blending blocks the dialer from placing outgoing calls for that agent. In short, it removes them from the algorithm for a set time.

7. Call Routing

Call routing is a call management procedure for both incoming and outgoing calls. As a result, it ensures calls reach the appropriate agent or department. In addition, it can identify VIP customers and route them to faster or shorter queues.

8. Customer Relationship Management (CRM)

Customer Relationship Management (CRM) is an approach organizations use to engage with customers. For example, a CRM uses several systems to determine customer needs. As a result, it improves interactions, sales approaches, and contacts. In short, it helps companies retain customers, expand their base, and boost sales.

9. Document Management Systems (DMS)

A DMS is a computer system that is utilized to track, receive, manage, process and keep files and documents. Its purpose is to make document processing smoother, faster, and more efficient. In addition, it reduces reliance on physical documents and tracks changes and version updates.

10. Dialed Number Identification Service (DNIS)

A DNIS is a service that telecommunication vendors provide. As a result, it enables call centers to identify the number a customer dialed on an incoming call.

11. End of call disposition

End of call disposition is a call status that shows the reason for the call and its outcome. In addition, it can determine what action to take next.

12. Expected Wait Time (EWT)

EWT refers to the amount of time a customer should expect to wait before speaking to an agent.

13. First Call Resolution (FCR)

An FCR is an important metric that measures the quality of service customers receive during calls. For example, a case management application or a CRM usually supports it. In short, it tracks the calls that agents resolve at the first point of contact.

14. Flushing out the Queue

Flushing out the queue refers to redirecting large volumes of calls to a different group of agents. As a result, customers reach an agent faster and avoid long waiting times.

15. Healthcare call center

A healthcare call center, also called a medical call center, specifically serves clients in the healthcare industry. Besides inbound and outbound calls, it also supports appointment scheduling. In addition, it handles pharmaceutical services, insurance claims, and revenue cycle management.

16. Helpdesk

A helpdesk is one of the call center terminologies for customer support. For example, it serves computer software and hardware providers. In addition, it can take calls about a specific product or service.

17. Idle time

Idle time is the time an agent was unproductive during working hours. In short, it is time not spent on calls or after-call work.

18. Interactive Voice Response (IVR)

An IVR is an automated phone system. For example, it lets callers get information through a recorded message or voice response. Callers receive information via voice recognition or keypad signaling. Then, if needed, the system directs the call to the correct agent or department.

19. Judgemental forecasting

In judgemental forecasting, ideas, beliefs, and opinions form the basis for predicting an outcome. In short, it relies on judgment rather than statistical facts. For example, its key fundamentals are market research, intuition, and the opinions of business leaders.

20. Key Performance Indicators (KPI)

A KPI measures the overall performance of an organization. For example, it evaluates and analyzes different specified metrics.

21. Live Monitoring

Live monitoring observes real-time calls that agents make. As a result, it helps managers gauge how agents assist and handle callers. In addition, teams often use it for coaching sessions and quality assurance.

22. Machine learning

Machine learning is a branch of artificial intelligence. For example, it uses algorithms and data to learn with little to no direct human instruction.

23. Net Promoter Score (NPS)

NPS is a market research metric in the form of a single survey. In short, it aims to determine customer loyalty and satisfaction. In addition, it gauges how likely customers are to recommend the brand to others.

24. Omnichannel

Omnichannel in a call center means the operation delivers customer service across multiple channels. For example, these can include live chat, texts, video calls, social media platforms, and other communication apps.

25. Predictive dialer

A predictive dialer is an automatic dialer that automates outgoing calls. For example, outgoing calls begin while agents are still on calls. As a result, by the time one call ends, another is ready to handle.

26. Quality Assurance (QA)

Quality assurance is a process an organization sets. As a result, a product or service meets the required qualifications.

27. Real-time data

Real-time data are sets of information that agents collect or record during a call.

28. Screen Monitoring

Screen monitoring lets managers or supervisors view remotely what agents are doing on their computers. For example, a specific screen monitoring tool makes this possible.

29. Telemarketing

Telemarketing is a method that uses outbound calls. For example, it aims to market, promote, and sell products or services.

30. Voice Recognition System (VRS)

A VRS is a telephone system that uses speech recognition. For example, it can interpret dictation, automatically dial numbers, or collect information from callers.

Overall, whatever type of call center you work for, knowing the proper call center terminologies helps. For example, it helps you deliver great service, explain complex issues clearly, and improve customer satisfaction. To learn more, you may also head over to our Glossary page.

Why are call center terminologies important for agents?

They give agents a shared language for handling calls and measuring performance. As a result, teams communicate faster and make fewer errors, because everyone uses the same terms.

What is the difference between AHT and FCR?

Average handle time (AHT) measures how long an agent spends per call. Meanwhile, first call resolution (FCR) measures whether the issue was solved on the first contact. As a result, together they balance speed and quality.

Where do agents learn call center terminologies?

Most agents learn them during onboarding and training. In addition, they pick up more terms on the floor while taking live calls.

What is the difference between a call center and a contact center?

A call center focuses mainly on voice calls. Meanwhile, a contact center handles voice plus other channels, such as chat, email, and social media.

Which call center metrics matter most?

Common priorities include AHT, FCR, NPS, and abandoned call rate. However, the right mix depends on whether the operation is inbound, outbound, or blended.
