Virtual phone system for UK businesses
Run your business from anywhere with a flexible virtual phone system designed for customer service, sales, and every business call in between.
What is a virtual phone system?
Virtual phone systems give small businesses a simple, cloud-first alternative to a traditional phone system. Powered by VoIP technology, they support features like virtual phone numbers, voicemail, and unlimited calls across multiple devices. Unlike a traditional phone system, virtual phone systems rely on internet protocol (IP), meaning you can take calls from anywhere using a mobile app, desktop interface, or VoIP phone.
They’re ideal for small businesses, startups, and remote teams who want to look professional and stay responsive without being tied to a desk phone or office-based phone line.
How does a virtual phone system work?
Calls are delivered via a VoIP system, converting each voice call into digital packets using internet protocol. These are then routed securely to your chosen device via your VoIP provider. Whether it’s a mobile app, IP phone, or softphone, the process is fast, reliable, and crystal clear.
Features like call forwarding, voicemail, virtual phone lines, and call menus are all handled in the cloud by your virtual phone system provider. No hardware. No cabling. Just fast, flexible business communication powered by the internet.

Matthew Burton
I have used B4BC for almost 6 years now with my existing business & when it came to setting up my broadband / phone provisions for a new business I went straight to B4BC. These guys have exceptional customer service & take all the stress off your plate so you can focus on the million other things you need to take care of within your business. Could not recommend any higher!
Krishna Pariyar
B4BC has been the best system that I have used so far. They have solutions for every business phone system. The app works on both the desktop and phone, which have made operations convenient. Their support is great with response time and requests. And it’s really easy to reach the Account Manager through email, website chat support, phone and support ticket.

Use B4BC for all our telecoms and its a breath of fresh air compared to who we used before. Recently moved our energy management through them and I’m equally as impressed. I wouldn’t hesitate for a second to recommend them.

Fortunately getting in touch with the team at Best 4 Business is very easy, there are no long call queues so you’re not left on hold for ages & you don’t have to go through lots of different options before being connected to an actual person. The issues I have experienced have been dealt with immediately.

Changing my entire office phone system and broadband is no small task, in fact it’s quite daunting. However luckily or really thanks to Google I found Best4 Business. These guys at B2B are just brilliant! I now have a new VOIP phone system, massively quick broadband, great phones, ongoing support and I have saved nearly £200 a month. Happy owner!!
