Best VoIP phone service for businesses of all sizes

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:

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 internet connections.

Key features of VoIP business phone services include:

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.
