Need to get to grips with VoIP providers first? This comprehensive guide has been compiled by our telephones systems expert, exploring the ins and outs of top-rated UK providers and VoIP products in 2020.
What is a VoIP phone system?
VoIP stands for Voice Over Internet Protocol and refers to the software-based technology which allows businesses to make their telephone calls using a broadband internet connection, rather than through traditional phone lines. Take a look at how it all works:
VoIP phones systems convert the sound signal of users' voices into digital data streams, which can then be sent in “packets” over the Internet.
The signal is passed through an Ethernet cable to the VoIP server or gateway, before connecting with the Internet. Investing in a VoIP Phone system means a business has the freedom to use a variety of different devices to make and receive calls, including physical IP phones, computers or laptops, and smart phones.
Once you’ve set up a VoIP phone system, get ready for cheaper domestic calls and low price per minute international calls, too.
VoIP desk phones can either be set up as a new system or integrated into an existing one.
If you’re looking to integrate business phone systems, contact your current system supplier for advice.
In this guide, we've highlighted 11 of the best VoIP phone models in the corded and DECT (cordless) phone categories. Each of them will integrate fully with a VoIP phone system.
What is hosted VoIP?
With hosted VoIP, the infrastructure is based ‘in the cloud’ rather than on your premises. A service provider owns, manages and maintains the infrastructure in a secure data centre. You pay a monthly fee to use the service. Most businesses find hosted VoIP to be the best option as it’s so easy and low-maintenance.
It takes about thirty seconds to complete, and it's free. When you're done, you'll receive quotes from several leading VoIP telephone system suppliers. Why not give it a try?

About 4Com's VoIP phone systems
4Com provides three hosted VoIP options – on-premise PBX with Samsung phones, HiHi phones on a fibre line, and HiHi phones on a leased line. Given that the HiHi options come with unified communications (UC) apps, video conferencing (infinitely important for a remote workforce), and easy plug-and-play installation (also important for users getting set up from home), those are the systems we'd recommend.
According to 4Com, its fibre line HiHis are suitable for smaller businesses with three to 100 employees, while its leased lines suit larger businesses with 100 or more employees, and bigger bandwidth needs.
HiHi VoIP phones are thoroughly modern, with large touchscreens that double as detachable tablets that your staff can load up with your business' chosen comms apps.

Vonage Business Communications (or VBC, as it's also known) incorporates mobile calls, video meetings, instant messaging, contact centre calls, and more.

Benefits of VoIP for your small business
VoIP brings several benefits for your business, no matter the size. Let's take a look four ways a VoIP system can help your business grow.
1. Reduce costs
The adoption of a VoIP (Voice over Internet Protocol) telephone system for your small business can drastically reduce both your capex (capital expenditure) and opex (operational expenditure).
In other words, not only is it a great long term investment, but it will start saving you money on your calls from day one.
Providers such as One2Call offer free inter-site communication, which is hugely beneficial for your business, especially if you're looking to expand. Providers offer VoIP to UK landline calls for as little as 1p per minute.
2. Flexible and mobile communications
VoIP systems can work from any location with internet, or via a VPN (virtual private network). This makes them a great choice for if you run a smaller business, with staff who work from home. Telephone numbers can be retained and will remain directly associated with the main business office, allowing employees to use the same service.
One good example of what UK VoIP providers can offer your small business comes from Voipfone, who deliver up to 800 different extensions (per account).
These can be placed in any physical location, in the same office or internationally, and calls will be free of charge.
3. Enable growth
VoIP offers the potential to scale up operations as your business continues to grow.
Additional ports can be easily configured and brought online to provide for an extended service, or withdrawn and taken down when you no longer need them.
This can all be achieved seamlessly without disruption or down time, ensuring that communication between your employees and customers will not suffer.
The V-Plan Business VoIP package from Vonage (from £12.25 per month) gives you unlimited dialling to UK landlines, as well as unlimited calls to Hong Kong, China, Singapore, Canada and the US. This makes it a great option if your business is looking to expand into exciting new territories.
4. Connect to the future
Studies have shown that over 45% of UK businesses were already using VoIP phone systems in 2016 and that the majority of the rest would be doing so in the near future. And with call charges of up to 50% lower than BT and other providers, it’s no wonder so many savvy small businesses in the UK are making the switch. Are you?
VoIP Phone Accessories
Some businesses choose to invest in VoIP headsets, which have a number of benefits including increased employee comfort when making long calls, freeing your hands for other tasks such as using a computer while you are on the phone and freedom of movement.
The latest models have significantly improved sound quality compared to earlier handsets. There are a number of different VoIP headphones available with prices starting from around £20 per set.
Other accessories available include conference call sound stations, and cases to protect cordless phones. There’s a wide range of suppliers of VoIP telephone hardware, so shopping around is always a good idea.
