With the UK telecom sector expanding, VoIP services are becoming increasingly popular in how businesses communicate. This presents a compelling opportunity for IT resellers and managed service providers (MSPs).
If you are an IT reseller, you can provide business phone systems without having to build anything yourself. This is where white-label VoIP comes in.
But the VoIP partner you find is important. Selecting a reputable VoIP provider will result in satisfied customers, consistent monthly revenue, and a brand that exudes a sense of being entirely self-built. On the other hand, if you choose a subpar provider, you will find yourself burdened with hidden fees, limited capabilities, and outdated systems that will irritate your clients.
In this guide, we have researched and found the top five white-label VoIP providers. We have discussed them in detail, so you choose the one that fits your business.
What Is White-Label VoIP?
White-label VoIP is the practice of applying your brand to a product or service and then offering it as though created by yourself. The service handles all the challenging tasks in the background. The provider manages the servers, call routing, and upkeep, while you oversee the customers, pricing, and relationships.
For UK resellers, this is a model that makes sense. You skip long years of development work and costly infrastructure and just focus on selling, supporting and growing your business instead. You benefit from the monthly subscription, and you pay the provider a wholesale rate.
Here are the key features of white-label VoIP services:
1. Operational Autonomy
When working with a white-label provider, you are in charge: you determine the prices based on market conditions, bill clients directly so the money lands in your account, and are responsible for providing support and customer service to your customers.
All VoIP providers allow resellers to build their own support systems, create unique service offerings, and even build subreseller programmes for greater market coverage.
2. Future-Proof UC&C Features
Today’s businesses require more than just phone calls. They expect video meetings, team messaging and integrations with the tools they already use, and UC&C encompasses all of this.
Reputable white-label VoIP providers have all these features built-in. Your customers receive auto-attendants, call recording and mobile apps that allow them to work from anywhere. So, instead of just phone lines, you get to sell a complete solution.
3. Full Customisation And Branding
Giving full branding control is one of the main features that define a reputable white-label VoIP provider.
When you work with a reputable VoIP provider, you get full access to customisation and branding: your logo is shown on the login page; you can see your colours in the mobile app; the web address has your company’s name; and even email notifications and invoices carry your brand name.

Advantages Of White-Label VoIP Providers
The financial and operational advantages of white-label VoIP providers are vast. An understanding of these benefits will help companies see whether this model aligns with their business objectives and growth:
1. Less Capital Needed
Building a telecommunications business requires significant capital expenditures. White-label VoIP takes away the need for those capital expenses, and a business can come into the marketplace with very little financial commitment. The result reduces the entry price significantly for newcomers.
2. Quick Market Entrance
It takes multiple years and unique skills to create your own VoIP technology. White-label solutions deliver quick access to tried and tested platforms, meaning you can get services up and running in weeks rather than years.
3. Recurring Revenue Stream
White-label VoIP services will provide predictable income per month and improve the value of your business. With a monthly subscription, you will get a fixed monthly revenue, which can grow your business.
4. No Complexity Of Scalability
As businesses grow, white-label VoIP providers scale with ease without additional investment in infrastructure. The VoIP provider handles capacity planning, server scaling, and network tuning.
5. Focus On Sales
When you work with a reputable VoIP provider, they oversee the technical aspects and infrastructure management, which allows you to focus on sales, marketing and customer service: the only activities that bring in money.

Now let’s discuss each provider in detail:
1. Bicom Systems:
Overview:
Bicom Systems was founded in 2003; they built their platform for resellers who want everything in a single place. Instead of cobbling together a collection of billing, phone services, and management tools, you have one system that does it all.
The firm works with resellers worldwide; its platform is suitable for small startups that are stepping into the telecom industry.
Key Features:
Bicom Systems provides a full range of features well-suited to meet business communication needs:
- It allows you to handle unlimited customer accounts from a single platform while providing full security and privacy.
- Bicom Systems is a full-stack VoIP provider that offers PBX for call management, gloCOM for softphone and collaboration management, and sipPROT for security.
- It also has a billing platform, which deals with invoicing, customer management, and reseller hierarchies.
- It allows full branding; you can display your logo and colours in the portal, app, and client documentation. You can license this product without Bicom Systems branding.
Best For:
Proven VoIP resellers and telecom startups looking for an all-in-one solution. Its billing feature is what makes it a great option for resellers who intend to scale up or even recruit sub-resellers below them.
Pros and Cons:
| Pros | Cons |

All-in-one platform including billing |
High learning curve |
|

|

Bicom Systems hasn’t listed its standard pricing on its website. Prices vary depending on which modules you require and the number of users.
They tend to work on a revenue share or per-user wholesale rate. Contact their sales team for a custom quote.
2. Yeastar
Overview:
Yeastar began with hardware PBX systems and has progressively moved more into software and cloud-based offerings. They now have a white-label UCaaS platform that is very cost-efficient and has competitive features.
It works with resellers worldwide and focuses on doing things simply, so you don’t need to be a telecom engineer to use their platform.
In 2026, Yeastar is still pushing its fully branded experience; they are trying to make resellers feel as if they made the whole thing themselves.
Learn about the difference between UCaaS and VoIP in our guide: VoIP vs UCaaS: Which One Is Best for My Business?
Key Features:
- Yeastar’s white-label encompasses three primary aspects: the first is hosted PBX, which allows you to customise the login page, domain name, and email template; the second is the Linkus softphone app for Windows, macOS, iOS, and Android, which bears your logo; and lastly, a central monitoring platform that allows you to monitor everything.
- Yeastar lets you decide how things are hosted. You can let Yeastar take care of infrastructure, and you can focus on customers. Or you can self-host on cloud providers like AWS or Google Cloud for greater control.
- It is a single-interface platform with features like video conferencing, team messaging and a contact centre.
Best For:
IT service providers (ITSPs) and managed service providers (MSPs) are looking for cost-effective white-label solutions paired with modern UC capabilities.
Yeastar also serves resellers who want to sell cloud and on-site solutions, depending on what clients prefer.
Pros and Cons:
| Pros | Cons |
|---|---|
|
Pay-as-you-go pricing which keeps costs down |

Moreover, the full white-label branding comes with an additional charge.
3. 3CX
Overview:
3CX isn’t like other providers; they sell you software that you can host yourself or on their cloud. That gives you technical resellers more control but leaves you with less to rebrand.
The platform has excellent name recognition in the UK market. Most IT resellers are likely to identify 3CX by name, and this can help you when you begin selling.
Key Features:
- It comes with voice, video, live chat and CRM integrations all on one platform. You choose to host it on your cloud or let 3CX do the hosting.
- 3CX has extensive features such as call queues, IVR, reporting and mobile apps. It allows integration of popular business tools that many customers already use.
Best For:
It is ideal for IT resellers who have the technical expertise to handle hosting and maintenance. It is good for resellers who find a one-time licence more appealing than a recurring subscription.
Pros and Cons:
| Pros | Cons |
|---|---|
|
Offers competitive features |
3CX branding is slightly visible |
|
Flexible deployment choices |
Requires technical infrastructure for hosting |
|
Some clients save money with per-call licensing |
Not designed for big multi-tenant deployments |
|
One-time licence options available |
|
Pricing:
3CX pricing varies based on hosting and whether you buy licences or subscriptions. Annual subscriptions start at around £150 per year for the limited free tier.
4. RingCentral UK
Overview:
RingCentral operates at a massive scale. They have millions of users worldwide, and the name of their brand carries credibility. For resellers, this is good news, as you can sell a large quantity without having to explain the technology and the brand.
The catch is branding. Currently, RingCentral has reseller programmes, but they do not offer a true white-label. Your customers will know you’re using RingCentral because their names stay on the portals, apps, and invoices.
Key Features:
- It is a UCaaS platform that covers everything. Voice, video, team messaging, file sharing and integrations all work together.
- RingCentral has a solid mobile app, and most people like using the interface.
- The platform is reliable. It doesn’t go down, and if it does, support comes in no time.
- RingCentral manages the platform, reducing the technical overhead, while you handle sales and basic support.
Best For:
- This solution is ideal for resellers who want to add VoIP without requiring significant technical effort.
- RingCentral is particularly beneficial for generalist IT providers who are also selling other business solutions.
- It is also suitable for resellers who prioritise a strong brand over their own branding.
Pros and Cons:
| Pros | Cons |
|---|---|
|
Industry-leading platform reliability |
No white-label options at all |
|
Very strong UK and international presence |
Poor pricing and control over margins |
|
Minimal technical management required |
RingCentral owns the customer relationship |
Pricing:
RingCentral’s pricing is based on features. The core plan includes basic calling; the advanced plan includes multi-site management and integrations, and the ultra plan comes with device support and advanced analytics.
5. VIP VoIP
Overview:
VIP VoIP does not support any offshore or foreign infrastructure; every server is based in the UK, and the support answers are from the UK. It is ideal for resellers targeting UK businesses that want local providers.
They started the company with resellers in mind; they don’t sell to the end users, so your supplier is never a competitor. Each feature is there to enable you rather than try and take your customers away.
Key Features:
- It offers full white-label services, so everything is your brand. Your clients will never see another name on the online portals, the app, or the invoices.
- SIP trunks are built into the per-extension cost; their inclusion matters because many competitors tack on extra for every SIP trunk, and that can get expensive quickly. But VIP VoIP keeps it simple; you pay for what you need.
- Backup servers are included at no additional cost. Calls automatically go through another if one server is down. Your customers remain in touch without you lifting a finger.
- VIP VoIP offers industry-specific tariffs. They offer packages developed for schools, hospitality, and other segments that have their own calling patterns.
Best For:
They are ideal for UK resellers and MSPs who aspire to fully own the brand. It is great for anyone targeting UK companies that rely on local infrastructure.
Pros and Cons:
| Pros | Cons |
|---|---|
|
100% UK infrastructure |
UK-centric approach restricts overseas resellers |
|
Full white-label on everything |
Backup servers come with additional cost |
|
SIP trunks come with no extra cost |
|
Pricing:
VIP VoIP comes with straightforward pricing. Pay-per-extension pricing includes both the extensions and the SIP trunk in a single monthly price.
