What Is a Virtual Call Center?

Virtual call center software is a cloud-based application that uses Voice over Internet Protocol (VoIP) technology, allowing call centers to make high-quality online calls without bulky and costly physical hardware.

Traditional call center technology doesn’t cut it anymore. It slows down operations and drives up costs. Plus, remote work benefits employers and employees across industries — and that goes for call centers, too.

Virtual call center software helps distributed teams deliver a superior customer experience, even with high volumes of inbound calls.

With the right virtual contact center, you can reduce costs, scale your team, and go live faster.

Below, we’ll cover the fundamentals of virtual call center software, key benefits, functionality, and top tools to enhance agent performance.

How Virtual Call Center Software Works

Virtual call centers typically use a web-based application hosted in the cloud by a VoIP provider. This application enables call routing between the public switched telephone network (PSTN) and logged-in agents. 

An automatic call distributor (ACD) manages the call routing, distributing calls to the appropriate agents based on factors like:

  • Customer availability
  • Agent skills
  • Language preferences

You shouldn’t have to worry about the underlying technology of virtual call center programs — the call center provider takes care of it. Instead, invest the saved-up resources and time to coach and develop their customer service and sales skills.

🔎TLDR: Virtual call center software uses VoIP to connect calls over an internet connection rather than analog phone lines.

This allows a call center to be configured based on agent availability rather than their location. Anyone with a reliable internet connection can work as a call center agent from anywhere using an internet-connected headset, computer, or smartphone.

Traditional vs. virtual call centers

Virtual call center agents can work from anywhere. 

Traditional call center agents must work from a single location, often with on-premises telephony hardware in the building. 

Here are some key differences between virtual and traditional call centers.

Benefits of a Virtual Call Center: Why You Should Upgrade

Whether you’re deciding to move your existing call center to a virtual team or looking to start a virtual call center altogether, it pays to know the potential benefits.

A list of benefits of a virtual call center.

1. Organize your customer data

A virtual call center platform collects and organizes all the required metrics in a single dashboard. This empowers your team to create actionable, data-driven strategies and your agents to provide the stellar, personalized experiences your customers expect.

Your agents will be able to provide more personalized experiences for each customer when they can:

  • See previous conversations with a customer across channels.
  • Connect insights from your sales and support teams by integrating calls with your CRM.
  • Create automations for follow-ups and reminders.

This type of omnichannel contact center environment removes barriers to integrating data between channels and encourages cross-team collaboration. In return, your customers can benefit from a more fluid experience.


2. Communicate across several channels

To reach the most customers, your team needs to provide outreach via business communication channels such as email, social media, text messages, chatbots, and more.

A true omnichannel environment offers advantages like:

  • Separate apps, tools, or dashboards for agents to help customers on multiple communication channels
  • Intuitive, effortless travel between channels without endless phone tree menus
  • Faster customer service by routing the customer to the appropriate virtual call agent instead of bouncing around between departments and transfers

Your call center’s efficiency and your customer and agent satisfaction are tied to how quickly and how well customer questions are answered. Answer them faster with a more integrated omnichannel solution.

3. Boost customer satisfaction

Virtual call centers help agents help customers faster, increasing customer trust, loyalty, and satisfaction.

A solution that leads to positive customer satisfaction scores is worth investing in, thanks to:

  • Predictive routing to quickly connect customers to the right team member, which helps them straighten out issues the first time.
  • Live monitoring to ensure customers struggling to resolve their queries get help from supervisors jumping in on calls.
  • Continuous improvement from training and feedback customized agent-to-agent based on performance in live calls.

Together, these features empower agents to improve their customer service skills and capabilities.

4. Help your agents work smarter

The right virtual software can guide customers to help themselves, which eases burdens on your team, improves productivity, and raises satisfaction scores for employees and customers alike.

Virtual call centers help agents work smarter, which:

  • Improves agent productivity and efficiency
  • Reduces employee burnout
  • Lowers turnover rates

Running your virtual call center in the cloud can also help you handle higher call volumes. Nextiva’s software, for example, handles over 500 calls per line. You can take more customer calls with fewer agents to streamline call flows and distribute calls without issue based on varied daily and weekly agent schedules.

💡Tip: Nextiva’s AI-powered voice and chatbot power a comprehensive, customizable contact center solution that can help you take “smart” one step further — starting at $100 per agent per month.

5. Integrate seamlessly with third-party software

If your agents have to manually enter data from their customer calls into your other tools, you might benefit from adopting virtual call center software.

Connecting old-school call center software with modern apps and tools your business uses can be challenging. But virtual contact center tools include the following pre-built integrations for third-party software:

  • CRMs
  • Helpdesks
  • Ticket management
  • Productivity
  • Power dialers
  • Email
  • Shared team workspaces

Nextiva’s integrations work with (most) of your in-house tools and processes. Your agents will be equipped to seamlessly move between resources to help your customers better, enhance customer service, and boost overall efficiency.

Nextiva integrates seamlessly with most in-house tools and software like Google Workspace, Zendesk, and more.

A solution like Nextiva offers out-of-the-box business integrations for popular online tools like:

It also provides options for configurable setups with no-code API integrations.

The best call center software alleviates your contact center challenges and headaches. And if you’re thinking of migrating your entire operation to the cloud or starting a virtual call center from scratch, learning the benefits you stand to gain may make your decision easier.

6. Free up office real estate

A virtual call center is better for some companies than an on-premises one because it doesn’t require physical office space.

Since agents only need an internet connection and a headset, you can set up and install your virtual call center a few hours after signing up. When the time comes, simply onboard new virtual agents and scale up when you need the software licenses.

IT support also frees up time by reducing the number of hardware support cases they’d have to deal with on-site. They can focus on larger, more beneficial initiatives, like:

  • Enhancing VoIP security measures to protect the increased flow of data with a virtual call center
  • Optimizing and integrating software to improve agent efficiency
  • Exploring artificial intelligence (AI) automations to streamline operations

You can start a virtual call center with minimal investment or lower your operational costs for an existing one. You also score a more risk-free solution to scale as your business grows.

7. Increase reliability and geographic redundancy

When geographical boundaries don’t restrict agents, supervisors, and managers, everyone can stay connected from anywhere. Whether using the app from a home computer, tablet, or smartphone, calls and messages move seamlessly into the cloud.

This work-from-anywhere approach means you can provide 24/7 customer support and impeccable service without worrying about:

  • Bad weather
  • Traffic delays
  • Sick days

Scheduling remote agents in each time zone around the globe always gives your customers someone to connect with fast — and they won’t be able to tell the difference between an on-site or virtual call.

How to Choose Virtual Call Center Software

Finding the right solutions for your business is essential because every customer interaction counts.

The best call center software has key features that help businesses stand out from the competition.

So here are the top capabilities to look for to boost efficiency and help you scale:

  • Omnichannel functionality so agents can handle requests and share information across multiple channels
