Multi-line phone systems for businesses

Voice over Internet Protocol (VoIP) has been around for nearly three decades, but it’s so commonplace these days, that you might not be aware of the ways in which 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. 

Let’s look at real-world examples of how VoIP is used 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 90s as a way to make and receive phone calls from your computer or desk phone in an office. It uses your internet connection to establish voice calls together.

Today, VoIP technology real-time audio, streaming video, and exist 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 made 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. 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 provider would establish voice communications between multiple users internally. In many cases, these calls 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 Skype.  

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.

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. 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. 

In some cases, your team might not need the most advanced features immediately, but the advantage of VoIP is that they’re available when you want them.

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.
