Internet phone service
An internet phone service is a must for businesses that want to ensure flexibility, mobility, and scalability in their communications. With RingCentral RingEX, you get an AI-powered communications platform that handles internet calling, business SMS, and a whole lot more.
There are few things more important in business than effective communication. If your teams can’t collaborate efficiently, they can’t keep the company running smoothly or offer the standard of products and services your customers demand. That’s what makes an online phone service a must for modern business.
In the past, a landline-based phone system may have been enough. Today, though, you need to manage multiple communication channels, hybrid and remote workers, and more. Clunky, immobile on-premises systems, won’t cut it.
Internet phone services—or, better still, a unified communications platform like RingCentral RingEX with online phone services built in—are the only way to effectively meet consumer demand and keep up with your competitors.

It can be used to conduct interactive webinars as well.
Team messaging
Team messaging capabilities can also act as a powerful collaboration tool. Aside from its messaging functions, it also serves as a repository of tasks and allows users to create groups and teams for certain projects. But even with its useful functions, it is not a boring tool at all: use it to send emojis and even create your own company memes.
Business app integrations
RingCentral also integrates with the different business apps you use every day. This allows companies to add communication capabilities to their favorite tools like Salesforce, Google Workspace, and Office 365, among others.

Virtual extensions
Connect departments and office locations with virtual phone extensions. These extensions are based in the cloud, so you can enjoy flexible features that can be customized according to your specific small business needs.
What is an internet phone service?
An internet phone service, as the name implies, is a phone system rooted in the internet. Rather than using the physical network of copper wires and other infrastructure known as the Public Switched Telephone Network (PSTN) to transfer calls, it does so digitally over the internet.
That allows users to make and receive calls from anywhere using their laptop or mobile device. It provides small businesses and enterprises with the security, mobility, flexibility, and advanced call features that aren’t possible with on-premises phone systems.
How does an online phone call work?
An internet phone call is made possible by VoIP (Voice over Internet Protocol) technology. In the simplest possible terms, here’s how internet calling works:
- The voice signals you generate are converted into data packets.
- These packets travel over the network and out through the internet until they reach their destination.
- VoIP converts the packets back into voice signals for the person on the other end to understand the message.
From an end user’s point of view, online phone calls seem just like traditional ones. There are multiple ways to make internet calls, including:
- Through a landline phone with an analog telephone adapter (ATA) - A phone adapter connects a landline phone to a VoIP system to enable internet calls. Just plug your phone cable into the device, and you’re good to go.
- From PC to PC - Download a VoIP-enabled program, set up an online account, and start making internet calls. Call quality depends heavily on your infrastructure and bandwidth, so it doesn’t always make for an ideal business phone system, especially for small- and medium-sized businesses. Examples of this type of VoIP programs are Google Voice and Facebook Messaging.
- From PC to phone - Partner with a third-party software provider to connect your computer to a landline phone and make PC-to-phone calls. You’ll be able to leverage their VoIP services for a price which is still considerably lower than what a traditional phone company would charge.
- Using softphones and apps - Connect to VoIP using any handheld device. This net calling setup is ideal for businesses with a number of field or remote workers.
Internet phone vs conventional phone: The benefits of an internet phone service for business
- Quick and free implementation
An internet business phone service, then, offers myriad benefits to companies. At the outset, installation is far easier, quicker, and less expensive. An online phone system isn’t reliant on copper wire phone lines or voluminous hardware. Getting them set up and implemented is often the case of simply downloading software and customizing settings.
Another related benefit of an internet phone service for small business particularly is that ongoing costs are also typically more affordable and predictable. With a traditional, on-premises system costs are impacted by maintenance, call volumes in a given month, and more. With internet phone services for business, meanwhile, you often simply pay a set monthly subscription charge.
What’s more, the best business internet phone service gives you much more in terms of features and functionality than any traditional system.
