Let’s get started. 

What is computer telephony integration?

Computer Telephony Integration (CTI) is any technology that enables a computer to interact with a telephone. 

Such phone system integrations use the VoIP (Voice over Internet Protocol) technology that allows voice and other types of communication to travel over the internet. 

Telephony integration is primarily used in call centers to link a phone system to their business software. This way, it enables agents to have desktop-based interactions with the customers. 

Agents can receive incoming calls, make outgoing calls, and even complete other call-related tasks directly from a laptop, desktop, or mobile device. They no longer need a physical telephone device as they can perform all phone related functions using on-screen call controls. 

Moreover, as call centers evolve into contact centers, the term CTI has also expanded to include different customer service channels like email, live chat, and social media.

Now that we have a basic understanding of computer telephony integration, let’s explore more about this technology. 

6 key features of computer telephony integration

Here are some of the functions of CTI:  

1. Phone controls

CTI software offers phone control features like answer, hold, mute, call forwarding, conference, and hang-up.

This way, a call center agent doesn’t need to switch back and forth between the computer software and a physical phone to handle calls. 

Not only does this prevent distractions for the agent, but it also ensures better call management and focus over the entire customer interaction. 

2. Automated screen pop-ups

One of the essential features of computer telephony integration is screen pop-ups or screen pops

It’s a window that automatically appears on the agent’s desktop when a customer calls. This window displays complete information about the caller whose call is directed to that agent’s phone.

The screen pop feature in a CTI application can search through the software and display information needed to resolve a customer issue.

This information includes caller authentication via Automatic Number Identification (ANI) or Dialed Number Identification Service (DNIS). It also shows calling history and other customer data. 

With instant access to such information, agents can deliver a more personalized service. It also makes them more efficient as they don’t need to toggle between apps to look for customer data. 

3. Automated dialing

A CTI tool offers automated dialing features that include: 

  • Click-to-call. 
  • Predictive dialing.
  • Auto dialers.

With a click-to-call service, customers can connect with a call center representative via phone while using an app or browsing a website. 

On the other hand, agents can use predictive dialing or auto dialers to call a list of phone numbers automatically. When the software detects a connection, it passes the call to a live agent. 

How do these features help?
They allow call center agents to connect with more customers in a shorter period. It boosts employee productivity and helps meet targets faster.  

4. Call routing/transferring

Computer telephony integration can offer data-directed call routing and transferring using an Automatic Call Distributor (ACD). 

This means it can match data collected from inbound calls with a company’s database and then route it to the agent best skilled to handle the customer’s inquiry. 

So, if a Spanish-speaking customer calls, the software can search for an agent proficient in speaking the language and automatically route the call. 

Since a call center receives bulk calls every day, this helps resolve customer complaints more quickly. 

5. CRM integration 

A CTI system facilitates integration with your CRM system (Customer Relationship Management). This means you can access all customer information right from your CRM dashboard. 

You can also integrate it with a contact center platform, unified communications, or a VoIP PBX phone system. 

With such integrations, agents get the essential caller details on their CTI screen, including the historical data about the previous interactions. 

For example, let’s say a customer calls to enquire about a delayed refund. In this case, the agent already has details about the purchased item, date of purchase, date of return, the last call received, the status of the refund, etc. 

This way, call center or contact center agents can serve each customer better and resolve their issues accurately.  

6. Call recording and analytics

You can use a CTI tool to record and listen to calls right from the CTI screen. 

This allows agents to go through the previous customer interactions and understand their issues better. It also helps them deliver more personalized solutions to the customer in the future. 

Moreover, team leads can use this feature to give feedback to agents and help them improve their call-taking skills.

6 key benefits of computer telephony integration

Here’s why you should use computer telephony integration: 

1. Reduces costs

Computer telephony integration completely eliminates the need for a physical phone, which reduces its cost and maintenance. 

CTI integration also helps agents reduce their average call handle time. It means they can take more calls in the same duration without compromising customer satisfaction. 

Since a significant chunk of the call center’s running cost is spent on the workforce, telephony integration makes agents more efficient and reduces company overheads. 

Moreover, as CTI helps improve workflows, it keeps agents at ease and can reduce employee turnover. This can dramatically reduce the costs of hiring and training over the long run. 

2. Saves time

With telephony integration, agents can drastically reduce the time spent searching customer data, toggling between screens, and post-call wrap-ups. 

Since CTI combines all the information in a unified dashboard, agents can easily access all the essential information.  

Additionally, functions like click-to-call can reduce the time spent by agents dialing each number manually. This especially comes in handy when agents are working in a high call volume environment. 

3. Improves customer satisfaction 

As the CTI technology equips agents with a complete customer record, they can quickly authenticate a caller by matching the phone number with the call center database. 

So when an angry customer calls, they don’t need to repeat themselves and provide all the information to the agent from scratch.  

Moreover, with screen pop-ups, agents can have a customer record displayed in seconds, even before answering a call. They can greet customers by their names and don’t need to put customers on hold.

This telephony technology also greatly improves customer service because agents can provide tailor-made solutions and deals to clients based on their preferences. 

Additionally, the skill-based routing helps transfer calls to the most suitable agent, which further helps in improving customer satisfaction. 

4. Ensures smarter monitoring and performance tracking

CTI screens offer a unified dashboard to view how many calls are on hold, which agent is on the phone, and everything else that team leads require to monitor the workforce. 

Telephony integration can also give managers a detailed analysis of customer journeys through call logging and recording. All calls are logged automatically in real-time, along with the necessary call data. 

The CTI application then generates multiple reports based on this information. Managers can use these reports to measure agent performance and target Key Performance Indicators (KPIs.) 

5. Offers remote work capability and scalability

CTI telephony technology makes it possible to set up a remote call center with teams distributed worldwide. 

The software automatically distributes and routes calls to agents based on their skill-sets. 

With a CTI system, managers can easily add or remove agents from their teams. They can also quickly scale up a call center business to handle larger call volumes.

6. Facilitates agent training 

Telephony features like call recording, call whispering, and call monitoring can help managers guide and train new agents. 

They can also use call recordings to identify potential disputes with a customer and take corrective actions for future calls.

Surely, telephony integration can go a long way in improving agent experience and increasing customer satisfaction.
