What are VoIP phone systems?

VoIP stands for Voice over Internet Protocol. It’s a technology that lets you make voice calls using an internet connection instead of a traditional phone line.

When you speak into a device that’s enabled with VoIP, your voice becomes a digital signal. That signal travels over the internet and is reassembled at the other end. The process is fast and seamless, so the call feels the same as a regular phone call.

If you're choosing a business phone system, it's likely you'll come across VoIP. Many business phone systems now use VoIP because it’s flexible, affordable, and can be enhanced with helpful features.

What are cloud calling solutions?

Cloud calling takes VoIP further. It means you don’t need specific VoIP-enabled phones and equipment on site. With cloud calling you can use your mobile phone or laptops to access calling services and the service provider hosts the phone solution in the cloud.

A key benefit of cloud calling is that you have less on-site equipment to manage and maintain. You can often access cloud calling, video meetings, and messaging in a single unified communications solution. This gives your team more ways to stay connected without managing multiple different tools.

5 key benefits of VoIP phones for business

VoIP phones have changed how businesses communicate. Here are five of the most valuable benefits.

1. Low costs

A VoIP phone system can be cheaper than a traditional service. Local, long-distance, and international calls may cost significantly less. Many providers also offer predictable monthly fees, which makes budgeting easier.

For a small business with tight margins, these savings matter. Whether you run a café, a consultancy, or a start-up, VoIP helps you connect and manage costs.

2. Flexibility and mobility

VoIP systems often offer more than just calls. Features like auto-attendant help make sure calls don’t get missed and hunt groups help your team work more smoothly by distributing calls from a single inbound number.

Because VoIP runs on the internet, you can answer calls on any compatible device. Staff can pick up the business number from the office, at home, or on the go. A sales team travelling between client sites can stay professional and more reachable.

3. Scalability

It’s generally easy to add or remove users on a VoIP system or cloud calling solution. You don’t need specialised hardware or complex setups. You just need to assign a user a number and activate the features they’ll use.

This makes VoIP a strong choice for growing businesses. A new online retailer, for example, could start with a few lines and expand quickly, as staff numbers increase.

4. Enhanced security

VoIP calls can be encrypted, which enhances their security.

Security is vital for businesses that handle sensitive data, like law firms or accounting practices. Secure communication builds trust and helps protect client information.

5. Reliability and continuity

VoIP systems can often include redundancy and call forwarding. These features keep calls flowing during outages or disruptions. Staff can reroute calls to mobiles or log in from another location. For example, if your internet at work goes down, calls can still be taken on your mobile as long as it’s set up and connected.

This reliability and flexibility supports hybrid work and helps teams stay connected outside the office. A call centre, for example, can keep serving customers even if one site goes offline.

What types of businesses are VoIP phones suitable for?

A VoIP phone system that is supported by cloud calling can suit many different types of businesses.

  • Small, fast-growing businesses can use it as a cost-effective system that scales easily.
  • Businesses with remote teams or multiple locations can connect from anywhere with internet access.

The advanced features offered by VoIP and cloud calling solutions can be particularly useful if you need to manage a high volume of customer calls. In industries like real estate, and for law firms or consultancies, features such as call routing, voicemail-to-email and virtual receptionists can help you deliver a good customer experience and avoid missing calls. 

Is a VoIP phone right for your business?

VoIP phone systems with cloud calling, or integrated into unified communications solutions, can deliver a range of benefits for your business.

Consider opportunities to reduce or manage costs, enable flexibility and improve security or reliability of your business communications. Ultimately these benefits can translate to a better experience for your customer and efficiencies across your team.
