In today’s digital world, VoIP is quickly becoming the preferred telecoms choice for home phone telephone systems and modern businesses alike. 

VoIP is a convenient, reliable, and cost-effective alternative to legacy phone systems. It’s no wonder that the world of VoIP is expanding rapidly, with new business VoIP service providers popping up regularly. 

With so many VoIP phone solutions out there, choosing the right service provider to suit your business needs can be challenging. Whether you’re searching for a small business VoIP solution or an enterprise alternative, it’s important to know what to look for. 

To help you choose the best business VoIP phone service provider, we’ll cover:

What is VoIP?

Voice over Internet Protocol (VoIP, for short) is a technology that enables the transmission of multimedia content over Internet Protocol (IP) networks. When we talk about VoIP, we’re more often than not referring to voice and audio data; however, it is also the foundation of other forms of media transmission (such as video). 

VoIP is the main telephony component in cloud business communications solutions, such as RingCentral, a well-known VoIP business phone provider.

VoIP technology is used to facilitate phone calls and other telephony functions over the internet. Its users can make calls from any device with an internet connection, making it a more flexible and convenient option than traditional landline telephones.

How do VoIP phones work?

VoIP business phone service works differently depending on what it’s connecting calls to—it can connect to other VoIP lines or traditional landlines.

VoIP works through a set of telephony protocols that use packet switching technology to convert analog voice signals to data packets. These data signals are then sent across the internet. Here’s how a VoIP call works, step by step:

  1. When someone speaks into the device (IP phone, softphone), voice signals are compressed into data packets that are then sent to the VoIP service provider.  
  2. The VoIP provider routes the data signals to the receiver (the person on the other end of the call). 
  3. The data packets are received and uncompressed, so what the receiver hears is sound again.

VoIP business phones vs. landline phones: What’s the difference?

What makes VoIP stand out as the preferred technology for business communications? To fully grasp the power of VoIP, we need to understand how it works in comparison to traditional phone systems. 

Traditional landline phones operate using a Public Switched Telephone Network (PSTN). A landline telephone sends coded electricity pulses via copper wire phone lines to transmit soundwaves through a circuit switching method. 

Traditional business phone systems require business owners to configure an on-premises PBX that connects employees within a shared network. It requires a ton of hardware and a robust physical infrastructure to facilitate. Some key characteristics of traditional phones include:

  • High costs for on-premises hardware and maintenance.
  • Additional costs for hardware and service upgrades.
  • Dedicated physical phone lines.
  • High costs associated with international calling.

When businesses transition to a cloud PBX (also referred to as hosted PBX or virtual PBX), they no longer have to host software on a server in the same way analog systems do. Instead, cloud PBX phone systems host all of your data and software in the cloud. They use VoIP technology to facilitate the transmission of calls through an internet phone service.

Key features of VoIP business phone services include:

  • Little to no on-premises hardware is required to facilitate a business VoIP phone.
  • Quick and easy to implement with low maintenance costs. 
  • Easy to add new phone numbers or repurpose existing ones.
  • New features can be added at little to no additional costs.

The key difference between landline phones and modern business VoIP phones is the technology required for the phones. Landline phones may have limited features, while VoIP phones are digital phones that can have features that can be enabled.

A landline office phone limits what your employees can do, allowing for only the most basic calling features; Internet phones, on the other hand,  allow for voice, video, and unlimited extensions that can empower your employees to communicate and collaborate effectively. 

If you’re looking for a VoIP phone solution that offers functionality across different office locations, mobile devices, and within the cloud, then VoIP is right for your business. Moreover, VoIP phones offer business benefits ranging from cost savings to increased flexibility.

How to make a VoIP phone call

There are several different ways to make a VoIP phone call. The method you choose will depend on your specific business needs and the equipment available to you.

  • VoIP phones or internet protocol desk phones: These might look like regular landline phones, but VoIP desk phones are much more than that. These phones are connected to the internet with wi-fi or Ethernet cables and can be used to make voice calls. 
  • Softphones: Softphone solutions are available through mobile or desktop apps. It can be accessed through a special app or software that is provided by the VoIP provider. You’ll also need a computer microphone, as well as speakers or headphones. With a VoIP mobile app, users can also connect a business phone number to the device via their VoIP system. 
  • VoIP Analog Telephone Adapter (ATA): This solution allows you to use your existing phones for VoIP calls. The analog-to-digital adaptor transforms analog signals to digital signals, making it compatible with VoIP transmission.

Advantages of a VoIP phone system

There are numerous advantages of switching from a legacy phone system to VoIP.

1. It can save you money.

Legacy phone systems require you to spend a lot up-front, and it becomes expensive (and difficult!) to make changes. VoIP solutions allow companies to save on costs related to:

  • Server infrastructure and hardware: With VoIP solutions, everything is hosted in the cloud. It removes the costs associated with implementing a physical infrastructure, hardware, and more. Moreover, they offer easy setup and require minimal up-front costs.
  • Adding phone numbers or services: VoIP allows you to adjust the number of users as your business grows, so you don’t have to pay to install new phone lines. Moreover, VoIP gives you access to a range of extra features and services that are expensive or unavailable with traditional phone systems. 
  • Long-distance calling: With VoIP, businesses can make international calls between VoIP-enabled devices, as well as use VoIP to make calls to local numbers at more affordable rates.  What’s more, VoIP allows users to make long-distance calls on a cell phone via a softphone app without incurring huge charges.

VoIP service for business solutions, too, are available at affordable prices. The cost of VoIP plans can vary depending on the size of your business and the extra communication and collaboration tools you require.
