Call Screening: Benefits, How it Works & Best Practices



Call-Screening-Benefits How it Works & Best Practices

Receiving unnecessary spam calls is a headache for a call center business where time is everything. You may miss an important call while trying to handle spam calls. 

This is where the call screening feature comes to the rescue. 😀

Call Screening plays a crucial role in eliminating unwanted calls 📞 and saving time. It lets you know who is on the other end of the line before you pick up.

This blog will discuss what it is, how to set it up using different methods, and its benefits to individuals and businesses.

So, let’s explore. 👀


  • In call screening, calls are identified before they are answered.
  • Call screening uses the CNAM database to identify the caller’s information.
  • Call screening increases productivity, saves time, and reduces spam calls for businesses.
  • Call screening software includes call blocking, caller ID, voice mail screening, and IVR features.

What is Call Screening?


Call Screening is the identification of phone calls before answering them. It lets you know who is calling. Caller ID is a minimum call screening feature, and the IVR System is an advanced form of call screening. The Caller ID allows you to identify callers by name and number before you answer the phone. IVR, on the other hand, enables you to determine a caller’s intent before answering.

The primary purpose of call screening is to eliminate unwanted calls and prioritize the important ones. With better call screening services, businesses can increase productivity, save time, and reduce spam calls.

How Does a Call Screen Work?

Call Screen uses the contacts saved on your device to identify incoming calls and decide whether to screen them. If there’s a number you prefer not to screen, you can simply save it as a contact.

Here’s a detailed process of how the call screen works:

  1. Receive the caller’s number: When you receive incoming calls, your phone system captures the caller’s number.
  2. Identify the caller’s name: Your carrier searches and finds the name using a CNAM database and displays it with a number on the screen.
  3. Ask for the caller’s name if it’s not found: If your phone carrier doesn’t find a name, the system will play a prompt asking the caller for their name and then announce it before connecting the call.

🔥 Note: Call screening must be activated for this.

  1. Check if the number is spam: The phone system also checks spam or robocall databases to see whether the number has been blocked or reported.
  2. Take automated actions based on the caller: You can set up automatic responses for incoming calls based on who’s calling. For example, you can choose to decline the call, send it to an automated menu (IVR), reply with a text message, or connect the caller to a live person.
  3. Connect to live agents with caller information: If the call reaches live agents, it will show them caller ID and name.

What are the Benefits of Call Screening?

Call screening is beneficial for businesses. Some of the benefits are:

Save Time

Call Screening verifies the caller’s name and number, which helps to transfer the call to the correct department based on history. For example, if a client always deals with a specific department, you can directly transfer a call to that department instead of asking from the beginning. It will save time for both customers and employees.

Reduces Spam Calls

Receiving a spam call directly affects a business’s productivity. Call Screening automatically terminates unnecessary calls and prioritizes crucial calls, reducing interruption.

Improve Productivity of Agents

With call screening features, agents can focus on work without interruption, such as spam calls. Call screen filters out unwanted spam calls and automatically terminates them. This helps agents spend their time on essential calls, ultimately improving agents’ productivity. 

Strengthens Customer Services

Call screening lets you know who is calling by showing the caller’s name and ID.  This lets you greet the caller by name and tailor the conversation based on previous interactions or customer history, making the customer feel valued and appreciated.

Call Screening Best Practices 

Some of the best practices of Call Screening are:

1. Robust CRM Integration

CRM Integration is an essential aspect of call screening. It allows agents to access customer data, such as customer call history, before taking a call. Knowing the caller’s information helps agents determine their actions regarding calls.

2. Distribute call path evenly

When setting up the IVR system, set it up to distribute inbound call volume evenly over your agents. Distributing calls evenly among agents shares the workload. It ensures fairness in the work and maintains quality and consistency in service.

3. Implement voicemail notifications for missed calls

Voicemail notifications for missed calls reduce the chance of unaddressed inquiries. These notifications remind agents to follow up and ensure they do not miss customer inquiries.

4. Self-service option

Provide a self-service option in IVR so customers can access required information without having to speak to human agents via menu options. This option empowers customers to resolve simple inquiries independently while complex ones are routed to agents, enhancing efficiency and customer satisfaction.

5. Use Caller ID

Before receiving calls, you should check the caller’s number and identity on display. Using Caller ID saves time and increases agents’ productivity. It enables users to pick up the call or not before checking the caller’s number.
