What is a virtual call? How it works and how your business can benefit

Is your business still paying for a phone system that ties you to a desk and charges by the minute? Virtual calls can help you ditch the landline, cut costs, and answer calls from anywhere — your laptop, your mobile, or wherever work takes you. In this guide, we'll break down what a virtual call is, how it works, the benefits for small businesses, and what to look for in a solution.

What is a virtual call?

A virtual call generally refers to a phone call made over the internet rather than through traditional telephone lines. Instead of relying on copper wire infrastructure, your voice is converted into digital data, transmitted over a broadband connection, and reassembled on the other end — all in real time.

Depending on the plan, virtual calls can be audio-only (like a standard phone call) or also support video. They can work on desktops, mobile devices, desk phones, and softphone apps, so your team can connect from wherever they happen to be working.

The technology behind virtual calls is commonly called voice over internet protocol (VoIP). If you've ever used a business phone app on your computer or made a call through a platform like Zoom Phone, you've already made a virtual call.

How does a virtual call work?

When you make a virtual call, here's what happens behind the scenes:

  1. Your voice is digitized. The microphone on your device captures your voice and converts it into digital data.
  2. Data is compressed and packetized. The audio is broken into small data packets and compressed for efficient transmission.
  3. Packets travel over the internet. Those packets are sent across the internet to the recipient's device or phone number.
  4. The call is reassembled. On the other end, the packets are decoded and converted back into audio — the person hears you in real time.

This entire process happens in milliseconds. With a reliable internet connection and a quality VoIP provider, virtual calls can deliver clear, dependable audio quality.

Virtual call vs. traditional phone call

  Virtual call (VoIP) Traditional phone call
Infrastructure Internet connection Physical phone lines
Cost Budget friendly monthly fees, often unlimited domestic calling Per-minute charges, hardware costs
Setup Minutes, no hardware required Requires installation, desk phones
Flexibility Call across devices from anywhere Typically tied to one device/location
Features AI summaries, voicemail transcription, analytics, integrations Basic call handling
Scalability Add users in minutes Requires physical line provisioning

The case for switching is straightforward: virtual phone systems are more affordable than maintaining legacy infrastructure, and they often come with features that traditional landlines simply can't match.

Virtual call vs. video call — what's the difference?

These terms are often used interchangeably, but they're not quite the same thing.

  • A virtual call generally refers to any call made over the internet — audio, video, or both. It's an umbrella term for internet-based calling.
  • A video call specifically refers to a call where participants can see each other via camera.

So all video calls are virtual calls, but not all virtual calls are video calls. A VoIP phone call to a customer? Virtual call. A face-to-face meeting on Zoom Meetings? Video call — and also a virtual call.

For most small businesses, the distinction matters most when choosing your setup: you'll want a platform that handles both seamlessly, so your team isn't juggling separate apps for voice and video.

Benefits of virtual calls for small businesses

Switching to a virtual phone system can do more than reduce costs — it can fundamentally change how your team communicates. Here's what small businesses gain:

Lower costs. Virtual call plans often start at a fraction of what traditional phone systems cost. You're not paying for desk hardware, installation, or costly maintenance contracts. See current pricing for Zoom Phone plans.

Work from anywhere. Your team can make and receive business calls on their mobile phone, laptop, or desk phone — from the office, from home, or on the road. One business number, across devices.

No IT required. Modern VoIP systems are designed to be set up and managed without specialized telephony expertise. You can configure call routing, add users, and customize your setup in minutes.

AI that does the work for you. The best virtual call solutions include built-in AI that can automatically capture call summaries, transcribe voicemails, and surface follow-up tasks — so you're not manually taking notes or playing catch-up after every call.

Scales with your business. Adding a new team member? Assign a number and set up their profile in a few clicks. No waiting on a technician to run new lines.

One platform for everything. The most capable virtual phone systems integrate calls with meetings, chat, and your other tools — keeping your communications in one place and minimize the app-switching that slows teams down.

What to look for in a virtual call solution

Not all virtual call systems are equal. When evaluating options for your business, you should pay attention to these factors:

Reliability and uptime. Look for a provider with a published service level agreement (SLA) that commits to uptime targets. Downtime can mean missed calls — and for small businesses, missed calls can mean missed revenue.

Call quality. A fast internet connection helps, but your provider's infrastructure matters too. Look for HD audio, background noise reduction, and network resilience designed to keep calls clear even when conditions aren't perfect.

AI capabilities — and what they cost. Many providers charge extra for AI features like call summaries or voicemail transcription. Look for a solution where AI is built in rather than an expensive add-on.

Ease of setup and admin. You shouldn't need a telephony specialist to manage your phone system. Intuitive admin tools and fast onboarding can save time and reduce support burden.

Integration with your existing tools. Does it connect with your CRM, your calendar, and the apps your team already uses? Integrations can help keep data in sync and reduce manual work.

Transparent pricing. Watch out for providers that charge extra for SMS, E911 support, or analytics. These costs vary by provider and plan.

How Zoom Phone makes virtual calls work harder for your business

Zoom Phone is a cloud-based virtual phone system designed for businesses that want modern reliability without the complexity. Here's what sets it apart for small and midsize businesses:

AI helps capture the details. Zoom Phone offers AI features — such as call summaries, voicemail prioritization, and task extraction — for eligible paid plans. After a call, AI summaries automatically capture what was discussed and what happens next, so your team can focus on the work rather than the admin.

Reliable calling you can count on. Zoom Phone offers up to a 99.999% uptime SLA and includes local survivability options — designed to help maintain calling continuity during outages.

A unified platform, not another silo. Zoom Phone works alongside Zoom Meetings and Zoom Chat inside Zoom Workplace, so your team can call, meet, and message without losing context between conversations.

Simple to set up, easy to manage. Set up your business number, configure call routing, and start taking calls from a single web-based admin portal.

Transparent, flexible pricing. There are no hidden fees. You can see the latest pricing for Zoom Phone plans on the pricing page.

Global reach. Zoom Phone offers global PSTN coverage across dozens of countries, with flexible bring-your-own-carrier (BYOC) options for businesses with existing carrier relationships.

Whether you're a solo consultant, a healthcare practice, or a growing retail team, Zoom Phone for small business is designed to scale with you — from one user to hundreds — without adding complexity.

Security and compliance in virtual calls

Security is one area where virtual call providers vary significantly. For small businesses, this matters more than it might seem.

When you make a virtual call, your voice data travels across the internet. A provider with robust security practices uses encryption and role-based access controls to help protect that data in transit and at rest.

Zoom Phone is built with enterprise-grade security controls, including:

  • Encrypted calls, including end-to-end encryption for supported configurations and call types
  • E911 support designed to help customers meet emergency calling requirements
  • Role-based access controls that allow admins to configure permissions without giving everyone full access
  • Compliance recording controls, including configurable consent prompts and call log tracking, designed to support customers' compliance efforts
  • HIPAA-supportive features for healthcare organizations managing sensitive patient communications

For small businesses in regulated industries — healthcare, financial services, legal — these aren't nice-to-haves. They're requirements. And with Zoom Phone, these controls as core features, not afterthoughts.

Frequently asked questions

What is a virtual call?

A virtual call generally refers to a phone call made over the internet using voice over internet protocol (VoIP) technology. Instead of routing through traditional telephone lines, your voice is converted into digital data and transmitted over a broadband connection. Virtual calls can be audio-only or support video, and they work on computers, mobile devices, and desk phones.

How does a virtual phone call work?

When you make a virtual phone call, your voice is digitized, compressed into data packets, and sent across the internet to the recipient. The recipient's device reassembles the packets and converts them back to audio. This happens in milliseconds — making the experience virtually identical to a traditional phone call, often with better audio quality.

Is a virtual call the same as a VoIP call?

Yes, for practical purposes. VoIP (voice over internet protocol) is the technology that powers virtual calls. "Virtual call" is the broader consumer-friendly term; "VoIP call" refers specifically to the underlying technology. In many business contexts, both mean the same thing: a call made over the internet rather than through a traditional phone line.

Is Zoom a virtual call?

Yes. Zoom Phone is a VoIP-based cloud phone system for making and receiving calls over the internet using your business phone number.

What do you need to make a virtual call?

You need three things: a reliable internet connection, a device (smartphone, computer, or desk phone), and a VoIP service or virtual phone system account. With a modern cloud phone solution like Zoom Phone, you can be set up and making calls in minutes — no hardware installation required.

Are virtual calls free?

Some virtual calling apps offer free person-to-person calls (like consumer apps). For business use, you'll typically pay a monthly subscription per user that covers your phone number, calling minutes, and features. See current pricing for Zoom Phone plans.

Virtual calls aren't the future of business communication — they're the present. If your business is still paying for a phone system that ties you to one location and nickel-and-dimes you for basic features, it's worth taking a closer look at what a modern VoIP solution can do for your team.
