Handling high-volume calls and monitoring agent performance in a call center is a challenging affair and requires meticulous efforts.

With CallHippo, automate call handling, routing, and monitoring to streamline agent performance and deliver superior customer support. Gain a leading edge in the competitive market space.

What Is a VoIP Call Center?

A VoIP call center solution is a software system that call centers use to handle a high volume of incoming and outgoing calls seamlessly. VoIP technology routes call over the internet. This is a major advantage over traditional call center phone systems that depend on telephone networks and wired connections.

how VoIP Call Center works

Using hosted VoIP call center solutions minimizes infrastructural requirements limited to a stable internet connection and a desktop/ mobile device. This makes it a preferred option for businesses against traditional systems that require expensive hardware installations.

As they function over the internet, using VoIP for call centers helps set up and manage a distributed workforce in a quick time span. Also, VoIP call center solutions come with a wide gamut of features that help streamline call handling, routing, and monitoring.

Reasons to Choose VoIP for a Call Center

Benefits of choosing VoIP for call center

Let us move ahead to understand why you must choose VoIP for a call center. From improving efficiency and scalability to lowering operational costs, VoIP call center software offers a multitude of benefits. Here are the most important among them.

1. Minimizes costs

A key reason why businesses prefer VoIP for a call center is that it helps reduce a major chunk of their costs. Traditional phone systems require dedicated phone lines, PBX systems, etc. that demand significant investments in infrastructure.

On the other hand, VoIP systems function over the Internet and do not demand infrastructural investments. A Microsoft study shows that using cloud telephony services can save 82% of business costs.

Also, VoIP call center solutions have monthly and annual subscription plans. They cost far lower bucks than the traditional phone lines. This helps reduce their calling costs. So, using VoIP for call centers helps businesses save hardware, operational, and maintenance costs.

2. Improves agent productivity

VoIP call center solutions have an extensive gamut of call management features. Call recording, analytics, real-time dashboarding, IVR systems, intelligent call routing, etc. are some of the important ones. All these features help automate call center functioning and enhance agent productivity.

For instance, automatic call distribution (ACD) systems help sort incoming calls and automatically route them to the most capable agents or departments. This helps reduce manual effort and time. Agents can divert their focus from performing administrative tasks to more critical tasks that require human attention.

A Cisco study shows that small businesses experience a 77% increase in productivity while using VoIP contact center solutions.

3. Enhances customer service quality

Using VoIP for call centers helps businesses improve their customer service quality. As VoIP systems automate call handling, they help businesses offer a prompt response to customer queries. This improves customer service quality.

Also, VoIP systems allow businesses to communicate across multiple channels like voice, text, video, audio, etc. Businesses can choose a customer’s preferred channel, which ultimately enhances customer satisfaction.

4. Higher flexibility

VoIP call center solutions offer a greater degree of flexibility to businesses. As they are not attached to a location, device, or other hardware equipment, VoIP systems help operate the call center from anywhere. For instance, you can engage with customers in the USA while being located elsewhere. This helps businesses save costs in setting up physical office space.

As VoIP systems do not require special hardware, businesses can access the call center solution using mobile phones, desktops, tablets, laptops, etc. This allows businesses to start with their existing hardware and scale gradually.

5. Easily scalable

Easy Scalability

VoIP systems are highly scalable. They allow you to scale your communication abilities by adding extensions through the app. Unlike traditional phone systems, you do not have to install new equipment or add new phone lines.

6. Call center analytics

By using VoIP for call center systems, businesses gain access to advanced call analytics. They can draw insights regarding customer service quality, agent performance, call quality, etc. Monitoring these metrics helps businesses make timely decisions and corrective actions to improve agent productivity and customer service quality.

Businesses using VoIP systems can spot changes and trends in customer expectations earlier than others. This enables them to earn an edge in the competitive business space.
