What is Business VoIP?

Voice over IP (VoIP) as a technology and service has improved in leaps and bounds in the last 10 years. Sound quality, reliability and customer service have been prime factors that have been focused on by the industry in large. Combine that with the growth of high speed Internet availability it quickly becomes clear why VoIP has been embraced by companies worldwide, with an average annual growth rate of 30%. The only requirement to use this service for your company is a Broadband connection because it sends your voice as "data packets" across the Internet instead of a regular phone line. You can continue to use your existing phones (with the addition of a special adapter), but most will invest in IP phones that directly plug into your Internet connection. Try our VoIP Test to check your existing Internet connection for compatibility with VoIP services.

Business VoIP Service Benefits

When searching the best small business VoIP service providers it is not a difficult switch to justify due to the many benefits and advantages that this technology and service can bring to an organization when compared to a traditional phone service.

Lower Cost

Selecting the best busines VoIP service can save your small business an average of 60%, and even up to 80%. The majority of these savings come from the lower cost associated with sending calls across the Internet and from lower regulatory fees. With the large and continual adoption of this technology the regulatory fees are increasing on this industry, as regulatory bodies try to get a piece of the pie.

Free Setup and Installation

Traditional on-premise phone systems are not only costly to buy they are also costly to install. They have to be installed by a technician and set up in your office space. The top business VoIP providers ship IP phones to you that are all programmed to work with their service and ready to simply plug in and use. If you are not familiar with business class phones then there may be a small learning curve in learning how to put calls on hold, transfer calls, set up voicemail greetings, and using their secure portal (if applicable).

Self Management

With everything being digital and in the cloud it makes it easy to manage your phone service yourself or by an administrator within your small business. No need for specialist skills when adding or removing extensions as your business needs change (whether growing or reducing). No need to call someone in to make the changes. In many cases you have complete control and some providers have a "white glove" service where they make changes for you, all with a few key strokes.

Simultaneous Calls

Traditional phone services are "circuit-switched", meaning each call requires its own dedicated connection. This is another cost driver as your company grows. With VoIP phone service you just need one (1) Internet connection to your business to enjoy simultaneous calling as it is a "packet-based" system.

Vast Feature Sets and Integrations

Large corporation phone system features such as auto-attendants, ring groups, music-on-hold and versatile voicemail options are now available to any sized business. Being a "digital" system allows for many productivity enhancing features as well as integrations into other cloud and web based systems (such as Email, CRMs and more) that your business may already use. Many providers include 30+ features in their low monthly fees. Traditional "analog" systems are limited with features and integrations.

Portability and Flexibility

Another advantage of being a "digital" system is that you can take your IP phone anywhere and plug into an Internet connection and use it, providing both portability and flexibility. Great for workers who telecommute a few days a week or for employees that work from home or away from the main office. Off-site workers are still an extension call away and can answer calls coming into the company's main number. This is not possible with traditional phone services.


Modern life has us connected to work more than ever before, especially with the advent of Smartphones. Many of the best business VoIP service providers include a Smartphone calling App, at least for Android and iOS devices, which puts the power of your business phone into the palm of your hand. Regardless of your location you can answer business calls as long as you have a data connection. This is great for those that are constantly on the go and in and out of the office. This is something that traditional phone systems can not compete with.

High Definition (HD) Sound Quality

Enjoy high definition sound quality on VoIP calls. Clearer and more crisp than the limited sound quality of traditional analog systems.

Low cost unlimited calling plans High local and long distance calling costs
No setup fees and no installation fees Expensive equipment and installation
Self manage using a secure online portal Service person required to manage
Simultaneous calls and 1 LAN connection Circuit switched technology, 1 call per line

Finding the Best VoIP Service Providers for Small Business

Here is a guide for finding the best VoIP service for small business based on your company size and needs:

1 to 2 Employees:

If you have a home based or very small office based business with only 1 or maybe 2 people and you do not expect to grow over time then check out our Small Office / Home Office (SOHO) VoIP solution section. This category includes some residential focused providers that offer similar services to SOHO businesses at low cost as well as business focused VoIP service providers.

1 to 200 employees:

This is the sweet spot for business VoIP phone service, sometimes referred to as hosted PBX, virtual PBX, or cloud-based communications. All the functionality of your phone service is "hosted" in the "cloud" and provided as a "virtual" service. What this really means is that all your IP phones connect to a server in a data center somewhere via the Internet. This server acts as your own Private Branch eXchange (PBX) and routes all your incoming and outgoing calls, as well as provides all the great features. Check out our hosted VoIP service section for more details.

On-premise PBX system:

Some businesses have invested serious capital into their own on-premise PBX system. This is the monster piece of equipment that lurks in your telecom closet. It is possible to upgrade some of these systems to an IP-PBX, allowing you to utilize Voice over IP technology to reduce monthly costs. Depending on the age of this equipment and level of investment it may be wiser to switch to a hosted solution and claim back that storage cupboard!

Businesses with a technical background or IT group may consider utilizing their own IP PBX also. There are several free and low cost open source solutions available such as Asterisk, FreePBX, Elastix, and 3CX. You then just need a SIP provider to connect you to the outside world. Check out our on-premise IP PBX phone system section for more information.

SIP trunking:

If you are using an IP based on-premise system you will need a SIP trunking service provider for VoIP calling. Check out our SIP Provider section for more information.

VoIP Equipment:

The most common hardware you will require for using with your VoIP service is IP phones. We have reviewed some of the major IP phones that many of the top business VoIP providers support. You can also find comparisons of headsets and adapters. Check out our VoIP Equipment section to learn more.

Wholesale VoIP:

Wholesale VoIP providers are the middle men that provide origination and termination of voice calls to the Public Switched Telephone Network (PSTN), and include users from hobbyists to VoIP service providers. Some wholesale providers aggregate tier 1 voice carriers and therefore can offer services to many areas around the USA as well as International calling, E911 calling and support, Caller ID lookup, and toll free services. Refer to the Wholesale VoIP section to learn more.
