5 best VoIP phone systems for small business

Every business needs to speak to its customers, suppliers and team members so telephone calls are vital for any business – especially if you run a service business relying on incoming calls and bookings or have outgoing sales calls. It’s also an area that has seen huge technology changes that now provide great features, flexibility and low price.

The technology that has driven all of these changes is called VoIP (Voice over Internet Protocol) and it allows you to make phone calls over broadband internet connections. Like your regular phone lines, VoIP relies on devices like business phones and smartphones but it can also be used directly from your laptop or from a special handset. If you’ve ever used a video-calling platform like Zoom, Teams or Skype, then you’ve used a version of VoIP.

Although VoIP uses the internet to route your phone call to another telephone, it normally lets you dial a telephone number. This is not the same as meetings organised over the internet via Zoom or Teams where everyone on the meeting call is using the same software. Confusingly, Teams and Skype can also dial out to a traditional telephone number as well as operate as a closed meeting. Take a look at our article on web conferencing software for more details.

When you setup your new business phone system, don’t forget to look at answering services to ensure all incoming calls are answered and you never miss a potential customer: VoIP systems can be setup to route via an answering services. And if you are looking for a quick and free way to start, you might consider getting a free telephone number for your business and then routing this to your business’ telephone system.

Benefits of VoIP for small businesses

There are plenty of benefits in using a VoIP system in your business. First, it can reduce your costs when compared to a traditional phone system that can be expensive to install, maintain, and has call charges. VoIP eliminates the need for separate phone lines and allows you to make calls over the internet at a fraction of the cost.

Second, VoIP is scalable which means that as your business grows, you can add new phones for new employees with very little cost – often just a software upgrade and headset for the laptop, making it a flexible solution that can adapt to your needs.

Lastly, VoIP has smart features built into most of the software platforms to improve productivity and efficiency – for example, automatic call transcription, call forwarding, contact management and more.

Types of VoIP phone system

There are two main types of VoIP phone system available: hosted VoIP and on-premise VoIP.

Hosted VoIP, also known as cloud-based VoIP, is a popular choice for small businesses. With hosted VoIP, your phone system is hosted and maintained by a third-party provider. This means you don’t have to invest in expensive hardware or worry about maintenance and upgrades. Hosted VoIP offers flexibility, scalability, and cost savings, making it an ideal choice for small businesses with limited resources.

On-premise VoIP, requires you to purchase and maintain equipment in your office or business premises. This option gives you more control over your phone system and allows for greater customization. However, it’s more expensive upfront and requires technical expertise to set up and manage.

Choosing a VoIP solution

When choosing a VoIP solution for your small business, think about your key requirements such number of staff making calls, do you need video conferencing or call analytics? Then think about the features you might like in your new system. Some to look out for include:

  • HD Voice Quality: Ensure that the VoIP phone system offers high-definition voice quality for crystal-clear calls. This is particularly important if you frequently communicate with clients or partners.
  • Mobile Apps: Look for a VoIP solution that provides mobile apps for iOS and Android devices. This allows you and your employees to make and receive calls on the go, ensuring seamless communication even outside the office.
  • Integration with business software: Check if the VoIP system integrates with your existing business tools and software, such as customer relationship management (CRM) systems or project management platforms. This will streamline workflows and enhance productivity.
  • Auto-Attendant: An auto-attendant feature allows callers to navigate through a menu to reach the appropriate department or individual. This eliminates the need for a receptionist and ensures efficient call routing.
  • Call Analytics: Look for a VoIP system that provides call analytics and reporting. This feature allows you to track call volume, duration, and other metrics, helping you make data-driven decisions to improve your communication processes.

Cost comparison: traditional phone systems vs. VoIP

One of the key advantages of VoIP for small businesses is cost savings. Let’s compare the costs of traditional phone systems versus VoIP to understand the potential savings.

Traditional phone systems typically require significant upfront investment in hardware and installation. Additionally, there are ongoing charges for line rental, long-distance calls, and maintenance. These costs can quickly add up, especially for small businesses with limited budgets.

On the other hand, VoIP eliminates the need for expensive hardware and installation. Many VoIP providers offer all-inclusive pricing plans that cover domestic and international calls, eliminating long-distance charges. Furthermore, system maintenance and upgrades are usually handled by the provider, reducing additional costs.

Deciding on this depends on so many factors. For instance, after considering the many unique needs of small businesses, we can tell you that RingCentral is fantastic.
