How it works
Despite the rise of Google Meet, Zoom and WhatsApp, VoIP (Voice over Internet Protocol) remains essential for businesses relying on high-quality voice solutions. Here’s how VoIP works:
Businesses
VoIP is vital for businesses with high call volumes and strict security needs, such as call centres, sales teams, logistics, distance educators, and telemedicine.
Integrations
VoIP wraps voice signals as data and transmits them online, similar to Zoom or Microsoft Teams, but with a large range of VoIP integrations, including to CRM systems.
Requirements
VoIP relies on stable, reliable, tethered broadband. Small offices may manage with SoGEA or Virgin Cable, but medium to large offices need leased lines or full fibre business broadband (50+ Mbps).
What are the key features of VoIP for business
VoIP offers a comprehensive solution for business communications, combining essential call management and robust security.
Below, we highlight some key features, but you can read more in our comprehensive guide to VoIP features for business.

- Call routing and forwarding for streamlined communication.
- Voicemail and voicemail-to-email options
- Caller ID, call waiting and call transfer capabilities.

- Privacy features to meet regulatory compliance standards
Choosing the right VoIP system for your business
The most important aspect of choosing the right VoIP system is assessing your business’s communication needs. Below are the three most important points to consider.
Number of users
Determine how many employees will need user access to the VoIP system. Consider both your current user numbers and potential growth to ensure you pick a VoIP system that is scalable.
Features requirements
Review our list of features and decide which are essential to your business. This is a great way to shorten your list of potential VoIP providers.
Call volumes and types
Understand your average call volume, peak times, and the types of calls (e.g., internal, customer service, international). To avoid additional charges, we recommend choosing a VoIP package that includes your standard usage within the monthly subscription.
Top VoIP Providers for businesses
There are many different business VoIP providers in the UK. Our experts have summarised the top five VoIP providers for small businesses:
- BT Cloud Voice – An additional extra on BT business broadband deals. BT also offers enterprise VoIP services for larger UK businesses.
- bOnline VoIP – Simple phone systems offered alongside bOnline business broadband deals, perfect for small business broadband customers.

What is the best VoIP phone system?
There is no single answer to which VoIP provider offers the best VoIP system. It depends on the needs of your business. Here are the key factors to consider when comparing VoIP systems:
- Customer support – We recommend reviewing Trustpilot for real customer reviews to see how a VoIP provider’s customer support department handles complaints.
- Pricing – VoIP system pricing plans can be complicated. Review and compare different VoIP pricing plans before making your choice.
- Free trial – VoIP systems do not require installation work, so we recommend taking advantage of the free trials offered by most providers.
- Scalability – Consider both the current needs of your business and what you may need in the future.
- Uptime – Businesses rely on their phone systems. Uptime is a key metric for comparing the reliability of VoIP system providers.
How much do VoIP systems cost?

Business VoIP FAQs
Our business broadband experts answer frequently asked questions on VoIP systems used by businesses in the UK.
Is VoIP cheaper than a landline for my business?
Yes, VoIP systems are typically cheaper than landlines.
Lower call charges, especially when calling abroad, are the most significant savings from a VoIP system. Even better, there’s no physical installation, so switching to a VoIP system can be completely free.
Do businesses have to use VoIP phones?
Not yet; there are still plenty of options available for traditional business landline systems. This is still the best option for properties that suffer from a slow internet connection.
However, be aware that in 2027, the UK will transition from the traditional copper landline system to internet-only calls.
💡Check out our explainer on getting business broadband without a landline.
Do you need to change your number when switching to VoIP?
No, transferring phone numbers from a landline provider or between VoIP systems is possible, so you can keep your old number.
Each VoIP system provider will have a page on porting numbers from an old supplier. We recommend reading and understanding this before proceeding with the remainder of the system setup.
What is hosted VoIP?
Hosted VoIP simply means that the VoIP system provider uses a cloud-based server to manage and route VoIP calls.
The alternative, “non-hosted VoIP,” means that you would have VoIP system servers based on your business property. This complex process requires expertise to operate and manage the system.
For most businesses, a hosted VoIP solution is the one to go for.
Can I get VoIP with a business broadband package?
Yes, absolutely. From 2027, VoIP will be the only option for business broadband packages. Many business broadband providers already offer a VoIP phone line with their low latency SoGEA and full fibre business broadband deals.
