5 Business VoIP Providers UK
National providers are telecoms suppliers who work with businesses of all sizes across the country; in some cases, internationally. Large national suppliers can offer some benefits such as slightly better rates, however they can also come with a number of downsides, including a less dedicated customer service experience.
- BT
- TalkTalk
- Vonage
- Virgin Media
- RingCentral

BT is the biggest name in the UK’s telecoms industry and the world’s oldest telecommunications company. dating back to 1846. BT operate internationally, meaning the scale of the business and their customer base is massive.

Much like BT, TalkTalk is a well-known VoIP provider in the UK, however they were only founded in the early 2000s. Considering the size of their brand and customer base, their growth has been rapid.
TalkTalk’s main focus is broadband and other types of connectivity, but they do offer VoIP solutions.

Founded in New Jersey in 2001, Vonage is an American-based business with a HQ in London. They have a large customer base both here in the UK and globally.
Vonage are a more business-focused VoIP provider who offer a range of different solutions. Alongside this, they also offer a number of collaborative tools to go alongside your VoIP system, including Salesforce.

Originally called NTL:Telewest, Virgin Media was founded in 2006 and was the first ‘quadruple-play’ telecoms company, meaning they were the first to offer TV, Mobile, Internet and Fixed-line telephony.
Virgin Media are similar to BT in terms of how they operate and what they offer, but they differentiate themselves by offering a more premium service. However, this USP does come at a higher price.

Similar to Vonage, RingCentral is a US-based VoIP provider with a UK HQ in London. They were originally founded in 1999 and their main HQ is now in Belmont, California.
RingCentral focus on supplying mid-sized and enterprise businesses with their own Hosted VoIP and collaborative solution.
Local Hosted VoIP Providers
Choosing the best UK VoIP provider for your business is just as important as choosing the right solution. Working with a telecommunications company that is local to you comes with a whole host of customer service benefits.
Often, local businesses have a smaller customer base than the larger national providers mentioned above, including here at Boxx. This means that we’re able to offer a more personalised, dedicated service, with the ability to visit customers on-site, even at short notice and give our customers their own account manager, who truly understands your business objectives can be reached each and every time you need to make contact...
