VoIP has been around for three decades, but it’s so commonplace that you might not know how VoIP helps people communicate reliably.
While the technology has evolved, it’s become a standard function in communication apps and a linchpin in business communication to meet increasing consumer and workforce demands. Voice over Internet Protocol (VoIP) enables voice and multimedia data to be transmitted over the Internet, offering benefits such as scalability, flexibility, and cost-effectiveness, which are particularly advantageous for remote workforces and improve overall productivity.
Let’s examine real-world examples of VoIP’s use across major industries and applications. We will also discuss several scenarios of how Voice over IP has helped companies scale their communications.
VoIP Overview
VoIP phone service has been used since the late 1990s to make and receive phone calls from a computer or desk phone in an office. It uses your internet connection to establish voice calls.
Today, VoIP technology provides real-time audio and streaming video and is at the heart of call centers. It’s the preferred choice instead of installing analog phone lines.

To appreciate the versatility of cloud-based telephony, let’s take a look at some of the sectors where it has had a big impact.
- Healthcare: From telemedicine appointments to staff communication.
- Education: Distance learning and virtual classrooms have benefited greatly from VoIP.
- Business: Startups and enterprises use VoIP for scalable, cloud communications.
- Telecommunications: The telecom industry relies on VoIP and related technologies for its backbones.
Types of VoIP Communications
When thinking about examples of VoIP, consider the nature of the communications. A VoIP system is highly effective in replacing traditional phone systems and enhancing business communication. Typically, all voice communications consist of the following scenarios:
- User to User VoIP
- User to Traditional Phones
- Traditional Phones to VoIP
User-to-User VoIP
Calls between users are where a VoIP phone system establishes voice communications between multiple users internally. These calls often occur over the Local Area Network, such as in an office building.
Popular in both personal and business contexts, this allows two or more users to communicate directly through the Internet. Examples of user-to-user VoIP include virtual meeting platforms like Google Meet or Teams.
User to Traditional Phone
Calling phones outside of the communication system is a core function of an office phone service. The service provider maintains superior call quality with data packets and relays voice calls to the traditional phone system. VoIP solutions provide cost-effective communication options and various functionalities like video conferencing and multimedia capabilities.
This form of VoIP facilitates calls from users to reach the public telephone network, such as cell phones, landlines, and other phone numbers. The practicality here is that users can talk with customers, partners, and employees on and off the phone system.
This is where voice over IP telephony delivers the goods. Anyone can make and receive calls, including international calls, for up to 90% less than landline phones. In addition to low-cost calling, users can also send and receive SMS/MMS business text messages.
Traditional Phone to VoIP
Calls that originate from the PSTN are connected through a VoIP service provider. VoIP service providers play a key role in securing voice over IP systems by using advanced technologies like encryption and maintaining secure networks through diligent practices such as regular audits and software updates. From there, the private branch exchange, known as a PBX, routes calls to the assigned user or team.
This arrangement is best for high-volume applications, such as at a call center. Incoming calls are held until they can be distributed to the appropriate team member. And since VoIP calls work over any broadband internet connection, the team can work from anywhere.
When thinking about VoIP applications for your organization, consider how users actually need to communicate with each other, customers, and partners. For instance, when replacing a traditional PBX, you might opt for a more cost-effective cloud PBX instead.
Sometimes, your team might not need the most advanced features immediately, but the advantage of VoIP is that they’re available when you want them.

Online Gaming
VoIP isn’t only used in the corporate world. It’s also found its place in online gaming. In games that require team coordination, in-game VoIP allows players to communicate in real-time, enhancing their competitiveness and overall gaming experience.
The current pace of scalable, low-bandwidth, low-latency audio could be traced back to the days of TeamSpeak or Ventrilo, popular voice chat servers used by gamers.
Personal Messaging
Interacting with friends and family on apps like WhatsApp, Viber, or FaceTime? That uses VoIP, too! These VoIP apps provide voice messages, video calls, and group chats. So, without even realizing it, you’ve been using VoIP in your everyday life.

Essential Business VoIP Uses
Communication is at the heart of business. VoIP improves communication features, such as how work gets done and how customers are helped.
- Call recording – Since VoIP is all-digital, voice conversations can be securely recorded in the cloud without additional equipment. Listen to past calls to identify areas for improvement.
- Call forwarding – Direct calls to another phone extension or phone number based on your desired criteria. Business call forwarding ensures every call is answered the way you want it on your terms.
- Interactive Voice Response (IVR) – An IVR routes incoming calls with a simple number-based menu so callers can reach their desired person or department. Since the call flows are virtual, you can update them in minutes.
- Three-way calling – A cloud–based phone system allows you to add a third person to a conversation instantly. VoIP makes it easy to dial another person and bridge the calls together.
- Group paging – When you want to broadcast a voice message to a department or all IP phones, VoIP allows you to dial a special extension to provide audio messaging.
- Call parking – It’s simple to switch devices (e.g., desk phone, mobile phone, computer, etc.) to continue your conversation uninterrupted. VoIP technology gives this a significant advantage over traditional landlines.
- Call queues – When your company has more telephone calls than people to answer them, you must place them on hold. This is known as a call queue. VoIP services specialize in providing on-hold messaging, call-back functionality, and call routing.
- Voicemail transcription – One of the benefits of VoIP is receiving voicemail messages in your email. These messages arrive with accurate transcriptions made better with the power of AI.
