59% of customers prefer communicating their questions and issues via live calls.

Most businesses have started using chatbots and AI to interact with customers. However, these means of communication are unsuitable for handling complex issues and situations. Furthermore, human interaction is required in most cases, which means call centers are still one of any business’s most important communication platforms. 

Businesses often need to have two separate call centers: one for handling incoming calls (inbound) and another for making outgoing calls (outbound) due to the differences in business needs, objectives, and seamless operation. So, businesses usually have two call centers: inbound and outbound. 

But what is the difference between an inbound and outbound call center? Let’s learn in more detail and find out which one you should prioritize more based on the size and nature of your business.

Overview of Inbound and Outbound Call Centers

An inbound call center handles incoming calls from customers seeking assistance, support, or information. On the other hand, outbound call centers make outgoing calls to customers or leads for various purposes, including sales, marketing, and research.

Inbound and outbound calls are completely different based on the direction of calls, skillset required for agents, nature of the business, and initiation of calls. 

Let’s learn more about the two types of call centers in more detail.

Inbound Call Centers

Inbound Call Centers

As the name suggests, inbound call centers receive calls from existing clients, customers, and prospects for various reasons, including seeking assistance, support, or information.

Inbound call centers are an integral part of customer service, and they are responsible for responding to questions, concerns, and issues as quickly and efficiently as possible.

Types of Inbound Calls

There are several inbound calls that a business receives every day. Although inbound calls are usually related to seeking assistance, support, or information, they can be categorized into four types which are as follows.

1. Customer Service 

Customer service calls are incoming calls from customers seeking assistance with inquiries, complaints, or issues regarding a product or service they have purchased. It is usually about goods and commodities returns, customer feedback, over-the-phone payments, policy questions, etc. 

During customer service calls, agents must provide support, address the issue, and ensure customer satisfaction, retaining brand loyalty.

2. Technical Support

An inbound technical support call comes from a customer experiencing technical difficulties with a product or service. Technical support agents assist customers in troubleshooting and resolving them to ensure that these technical problems are resolved.

Agents who are patient, calm and someone with in-depth product and service knowledge are required to handle these calls. 

3. Inbound Sales

Inbound sales calls are made by customers interested in a product or service. During the inbound sales call, the sales representative aims to convert the lead into a sale by providing information and addressing the customer’s questions.

The inbound sales call is not concerned with existing customers and clients but with potential customers, prospects, and leads. 

4. Upgrade and Renewal Inquiry Calls

This type of call is from existing customers who want to inquire about upgrading their current products or services or renewing their subscriptions. In addition to explaining the options to the customer, the representative facilitates the upgrade or renewal process.

Features of Inbound Calls 

Inbound call centers have some unique features that separate them from outbound call centers. Here are some primary functions of the inbound call center:

1. Direction of Call

Inbound call centers are concerned with incoming calls initiated by customers, clients, and prospects seeking assistance, support, or information. It might include queries, complaints, or requests for help. 

2. Customer-focused Approach

Inbound call centers are generally customer-focused, meaning that their operations revolve around meeting the needs and expectations of the callers, who are usually existing or potential customers or prospects.

3. Skilled and Knowledgeable Agents

Inbound call center agents must possess excellent communication skills, empathy, and product knowledge. They must be competent at actively listening to customers and offering personalized assistance.

4. Issue Resolution

The central function of inbound call centers is to resolve customer queries, complaints, or problems. As a result, agents must be trained to handle various issues and offer appropriate solutions.

5. Advanced Call Routing

Finally, the inbound call center intelligently routes a call based on factors like the caller’s language, geographical location, or the nature of the inquiry, ensuring the right agent handles each call.

Outbound Call Centers

Outbound Call Center

Outbound call centers proactively make outgoing calls to contact customers, leads, or specific target groups to achieve business goals. In contrast to an inbound call center, the outbound call center takes the initiative to contact prospects for sales, marketing, customer surveys, appointment reminders, and follow-ups. 

Outbound call centers are primarily responsible for driving sales, generating leads, gathering market insights, and maintaining customer communication.

Types of Outbound Calls

Like the inbound calls, there are various outbound calls. However, they can be categorized into two main types. 

1. Cold Calls

A cold call is a phone call undertaken by a business or individual to an unknown potential customer or contact. Typically, cold calls are not anticipated, and the recipient may not be familiar with the caller or the product/service being offered. 

Cold calling is primarily used to introduce a product or service, generate interest, and hopefully convert the prospect into a customer. Cold calling can be challenging as the caller needs to build rapport and overcome initial resistance from the recipient.

2. Warm Calls

Warm calls involve contacting individuals or lead with whom the caller or the business has some pre-existing connection or a prior point of contact. This connection could be through previous interactions, inquiries, website sign-ups, event attendance, or referrals. 

Since there is some familiarity between the caller and the prospect, warm calls tend to be more receptive and have higher chances of success than cold calls.

Features Of Outbound Calls 

Like inbound call centers, Outbound call centers have specific features. Some of the most important features of an outbound call center include:

1. Direction of Call

Outbound call centers focus on making outgoing calls to customers, potential leads, or specific target groups. The purpose of these calls can vary, from sales and marketing to conducting surveys, appointment reminders, or follow-ups.

2. Proactive Calling

Outbound call centers make outgoing calls to customers, potential leads, or specific target groups. The purpose of these calls can vary, from sales and marketing to conducting surveys, appointment reminders, or follow-ups.

3. Sales and Lead Generation

Driving sales and generating leads by promoting products, services, or special offers is one of the central objectives of an outbound call center. The outbound call center makes cold calls and approaches potential customers.

4. Scripted Conversations

Outbound call centers often use scripted conversations to ensure consistency and adhere to compliance regulations. As a result, the agents do not require the same technical and product knowledge level as agents of inbound call centers. 

5. Telemarketing and Sales Support

Outbound call centers often support telemarketing by following up on marketing leads or assisting customers in making purchase decisions.

Choosing the Right Call Center Approach

Choosing the Right Call Center Approach

Both inbound and outbound call centers are quite important for the success of any business. However, businesses might have to prioritize one call center over another based on their needs and objectives. So, here are some ways you can choose the right call center approach:

1. Identify the Business Needs

First, identify your business needs and objectives before prioritizing one call center. An inbound call center might be more suitable if your business aims to provide exceptional customer service, resolve inquiries, and maintain customer satisfaction. 

On the other hand, if the business aims to drive sales, generate leads, or conduct market research, an outbound call center could be the better choice.

2. Customer Preferences and Expectations

Assess and consider your customer base to know more about their preferences. An inbound call center would be more appropriate if your customers prefer reaching out for support or have specific inquiries. On the other hand, an outbound approach might be more effective if your target audience is receptive to proactive sales or survey calls.

3. Cost and Budget

Cost and budget are vital factors in any business. Assess your budget and resource availability before prioritizing one call center. Inbound call centers may require more agents to handle fluctuating call volumes, while outbound centers may focus on campaigns that require targeted efforts.

4. Business Scalability

Consider the future growth and scalability of your business. Virtual phone systems offer flexible scalability options that can accommodate changes in call volume and business expansion. More focus can be given to outbound call centers if the business is trying to scale up aggressively. 

However, inbound call centers can be focused on those businesses which have already reached a certain height and might not scale up much.

5. Agent Skillset

Evaluate the skillsets of your agents and the training required for each approach. Inbound agents need strong problem-solving and empathetic skills, while outbound agents should possess excellent communication and persuasion abilities. Consider whether your existing team can handle the chosen approach or if additional training is necessary.

6. Call Volume and Timing

Assess the typical call volume your business experiences. Inbound call centers often deal with fluctuating call volumes, while outbound centers follow structured call schedules. Understanding your call patterns can help determine which approach aligns better with your business.

7. Integration with CRM and Communication Channels

Determine how well the chosen call center approach aligns with your CRM system and communication channels. Seamless integration can lead to better customer data management and a more holistic customer experience.


Summing up, both inbound and outbound call centers are pretty essential for business success. Inbound centers focus on customer service and support, while outbound centers drive sales and achieve business objectives.
