How can AI be used in a call centre?

Ar­ti­fi­cial in­tel­li­gence (AI) is changing how service and support teams handle phone calls. Used in­ten­tion­ally, AI can automate parts of phone support, reduce the burden on employees and improve key service metrics. So how can AI be used in a call centre? Which use cases deliver the biggest impact? And which op­por­tun­it­ies and risks should you plan for?

Where can AI be used in a call centre?

A call centre sits within a broader customer ex­per­i­ence ecosystem, where companies connect with customers across a range of touch­points. Within that ecosystem, phone support plays a distinct role, as calls often involve urgent issues, complex ex­plan­a­tions or matters of a sensitive or personal nature. For that reason, AI in a call centre focuses primarily on phone in­ter­ac­tions, including inbound and outbound calls.

AI can be used across several parts of the call centre to reduce pressure on phone support and keep call handling running smoothly. AI works par­tic­u­larly well in call centres with high call volumes, recurring requests and time-sensitive inquiries. Common use cases include:

• Automated first contact: AI-powered phone as­sist­ants can answer calls, gather key details from callers and handle simple requests right away. This shortens hold times and allows agents to focus on more complex or con­sulta­tion-heavy cases.
• In­tel­li­gent call routing: Based on what the caller says, how urgent the issue is and any available context, the system can determine which team or agent is best suited to handle the case. This helps reduce the number of misrouted calls and increases the chance of resolving the issue on the first contact.
• In-call support: During a live call, call centre AI can pull up relevant knowledge base entries, highlight relevant details and make after-call work easier by gen­er­at­ing automatic summaries. This frees up agents and helps ensure customers get more con­sist­ent answers.
• Analytics and quality assurance: AI can analyse call data to identify recurring issues, common request patterns and quality gaps. Teams can use these insights to improve workflows, refine their training programs and optimise day-to-day processes over time.

What benefits do companies gain from using AI in an call centre?

When used in­ten­tion­ally, AI in the call centre improves multiple per­form­ance in­dic­at­ors at once. The biggest gains usually show up in ef­fi­ciency, service quality and cost structure.

Faster handling of service requests

Automated first contact, pre-qual­i­fic­a­tion and in-call support help reduce handling times. Average handle time (AHT) and first response time (FRT) often drop because callers get help sooner and calls follow a clearer, more pre­dict­able flow.

Higher first-contact res­ol­u­tion

Smarter routing and real-time agent support increase the like­li­hood that issues are resolved during the first con­ver­sa­tion. A higher first contact res­ol­u­tion (FCR) rate reduces repeat calls and frees up capacity across the call centre.

Improved customer sat­is­fac­tion

Shorter wait times, easier access to support and more con­sist­ent responses improve the ex­per­i­ence for callers. These im­prove­ments often show up later in metrics like customer sat­is­fac­tion (CSAT) or Net Promoter Score (NPS).

Lower costs and more efficient processes

Customer service auto­ma­tion reduces manual work and helps teams handle more calls with the same staff. This lowers operating costs and makes it easier to scale as call volume grows.

What chal­lenges and risks should you consider when using AI in a call centre?

AI can deliver real benefits in a call centre, but it also comes with legal as well as or­gan­isa­tion­al chal­lenges. To use AI suc­cess­fully, busi­nesses need to consider these risks from the very beginning.

Data privacy and com­pli­ance

Call re­cord­ings and audio data often contain personal in­form­a­tion and are subject to the UK GDPR and the Data Pro­tec­tion Act 2018. Busi­nesses must inform callers when calls are recorded or analysed and clearly explain the purpose of pro­cessing.

Or­gan­isa­tions need a valid legal basis for recording calls. This may include le­git­im­ate interests, con­trac­tu­al necessity or, in some cases, explicit consent.

Call data must be securely stored, used only for defined purposes and retained only as long as necessary. In more advanced use cases, such as large-scale speech or sentiment analysis, or­gan­isa­tions should also assess privacy risks and document how these are addressed.

Risk of errors and the need for human oversight

Outdated or poorly organised data can cause AI tools to give incorrect or in­com­plete answers. To avoid this, AI use cases need clear limits, content must be kept up to date, and critical decisions should not be automated end to end. In practice, AI works best as a support tool. It can assist agents during calls, but humans should always have the final say.

Employee ac­cept­ance

AI is changing how work in a call centre is done, and how roles are defined. If teams aren’t involved early on and trained properly, people are more likely to push back or feel unsure about the change. Teams are much more willing to embrace AI when it clearly supports their work. This is es­pe­cially true when AI takes over routine tasks and makes day-to-day work sig­ni­fic­antly easier.

Edge cases that require human expertise

Not every request can or should be automated. Emo­tion­ally charged con­ver­sa­tions, legally sensitive topics and par­tic­u­larly complex issues still require human judgement and empathy. AI systems should be able to recognise these situ­ations and hand the call over to an agent at the right time, ideally with a clear summary of what has already been discussed.

Which AI tech­no­lo­gies can you use in a call centre?

AI in call centres combines different tools depending on the use case. These tools help call centres un­der­stand spoken requests, handle calls more ef­fect­ively and support agents where it makes sense.

• Natural language pro­cessing (NLP) and natural language un­der­stand­ing (NLU): NLP) and NLU allow systems to recognise what callers say, un­der­stand their intent and sort requests by topic. That in­form­a­tion is then used for automated first contact, intent detection and struc­tured call routing.
• Speech-to-text and text-to-speech: Speech-to-text turns spoken language into text, so it can be analysed, doc­u­mented or passed on to other systems. Text-to-speech does the opposite by gen­er­at­ing natural-sounding spoken responses. Both are essential for virtual phone as­sist­ants and for sup­port­ing agents during and after calls.
• Real-time sentiment analysis: Sentiment analysis looks at tone, word choice and how a con­ver­sa­tion unfolds to gauge a caller’s mood. This in­form­a­tion is used to flag es­cal­a­tion risks early or provide agents with the right kind of support.
• Virtual phone as­sist­ants and IVR auto­ma­tion: Virtual phone as­sist­ants and voice-based IVR systems can be used to answer calls, collect in­form­a­tion and route callers to the right team. Compared to tra­di­tion­al IVR systems, AI-powered solutions let callers speak naturally instead of having to follow scripted prompts.
• Agent assist and knowledge base access: Agent assist tools provide agents with relevant in­form­a­tion during a call, for example from knowledge bases or other internal systems. This helps speed up responses, reduce errors and keep answers con­sist­ent.

How do you suc­cess­fully implement AI in a call centre?

AI delivers value only when it is rolled out in clear, man­age­able stages. A phased rollout allows teams to introduce new tech­no­logy without dis­rupt­ing daily op­er­a­tions, while giving agents and systems time to adapt. A typical rollout involves the following steps:

1. Start with the right use cases: Focus on high-volume in­ter­ac­tions with clear rules and limited risk, such as first-contact handling or initial call screening.

2. Prepare your data and knowledge base: AI relies on accurate, up-to-date in­form­a­tion. Assign clear ownership, remove du­plic­ates and structure content so systems always return the same answer.

3. Integrate with existing systems: Connect AI to CRM and ticketing tools so in­form­a­tion collected during the call remains available and does not have to be re-entered when the call is trans­ferred.

4. Pilot first and measure results: Start with a small-scale pilot to test as­sump­tions and identify risks early. Define clear metrics upfront and review them regularly.

5. Involve and train employees: Inform agents before rollout and provide training before the system goes live. This helps position AI as a support tool and reduces un­cer­tainty among employees.

6. Scale step by step and refine: After a suc­cess­ful pilot, the rollout can be expanded. Review call flows, rules, and processes regularly and adjust them as needed.

A real-word example using the IONOS AI Re­cep­tion­ist

The IONOS AI Re­cep­tion­ist is designed for automated first contact for inbound calls. It helps relieve pressure on service teams and keeps phone lines open, even during busy periods.

It answers calls around the clock, takes down requests and handles simple issues. It can also schedule ap­point­ments and direct calls to right team based on set rules. This helps cut down waiting times and keeps services running smoothly, par­tic­u­larly outside business hours or during busy periods.

Setup is kept de­lib­er­ately simple. Con­fig­ur­a­tion is rule-based and does not require changes to existing systems. After each call, agents receive clear summaries, typically by email, allowing them to continue the con­ver­sa­tion with all relevant details.

Data pro­tec­tion and security are also built into the assistant. Call data is handled in line with data pro­tec­tion re­quire­ments and clear limits are set for auto­ma­tion. When a request becomes complex, emotional or legally sensitive, the call is handed over to a human agent. As such, the assistant is designed to support agents, not replace them.

Which KPIs help you measure an AI call centre’s success?

To measure AI success in a call centre, it’s important to look at both op­er­a­tion­al per­form­ance and service quality. No single KPI tells the full story. The key is to compare several metrics over time.

Op­er­a­tion­al service metrics

• Average handle time (AHT): Measures the average duration of a call. AI can help reduce AHT by screening requests in advance or sup­port­ing agents during a con­ver­sa­tion.
• First response time (FRT): Measures how quickly callers receive an initial response. Automated first contact can sig­ni­fic­antly reduce response times, es­pe­cially during periods of high call volume.
• First contact res­ol­u­tion (FCR): Indicates how many issues are resolved in the first in­ter­ac­tion. In­tel­li­gent routing and agent-assist features typically improve this metric.
• Service level: Describes the pro­por­tion of calls answered within a defined time frame. It rep­res­ents a key indicator of service avail­ab­il­ity and is important for capacity planning.

Quality and sat­is­fac­tion metrics

• Customer sat­is­fac­tion (CSAT): Measures sat­is­fac­tion after an in­ter­ac­tion. Im­prove­ments are often driven in­dir­ectly by shorter waiting times and more con­sist­ent answers.
• Net Promoter Score (NPS): Measures how likely customers are to recommend a business and their overall per­cep­tion of it over time.
• Customer lifetime value (CLV): Rep­res­ents the long-term value of customer re­la­tion­ships and indicates whether improved service processes are strength­en­ing customer retention.

Retention and ef­fi­ciency in­dic­at­ors

• Churn rate: Indicates how many customers leave over a given period. A declining churn rate may suggest that service quality and ease of reach have improved over time.
• Auto­ma­tion and es­cal­a­tion rates: Show how many requests are handled auto­mat­ic­ally and how often cases are escalated to human agents. The aim is to maintain a balance between the two.
