VoIPninjas vs 3CX: Which Is Right for Your Business?
3CX is one of the most widely deployed business phone systems in the world. VoIPninjas is a direct UK VoIP provider with no resellers and no contracts. They are not the same kind of product, and the right choice depends on what your business actually needs.
This post explains what each option is, where each one genuinely wins, and who should use which.
What is 3CX?
3CX is a software PBX — a phone system that runs as software rather than dedicated hardware. You can deploy it on Windows, on Linux, or in the cloud. It is built on open SIP standards, which means it works with a wide range of IP phones and trunking providers.
3CX does not sell to businesses directly. It sells through a network of resellers and channel partners. If you want 3CX, you buy a licence through a reseller. That reseller deploys the system, manages updates, handles your support queries, and bills you for hosting if the system runs on their infrastructure.
There is also a free tier. It is genuinely free, limited to four simultaneous calls with some feature restrictions. For a very small business with light requirements, it works.
The reseller layer
The reseller model is worth understanding before you commit to it.
When you buy 3CX through a reseller, your day-to-day relationship is with that reseller — not with 3CX itself. The reseller sets your pricing, manages your system, and handles support. If that relationship breaks down, migrating to a different reseller means reconfiguring your deployment. If the reseller is slow to respond or makes changes without notifying you, you may not find out until something stops working.
This is not a criticism of 3CX the software. It is a description of how the product reaches the market. For businesses with an established IT partner they trust, this model can work well. For businesses without one, it introduces a dependency that has no obvious exit.
Maintenance overhead
Someone has to keep a 3CX system running. That means applying patches, monitoring uptime, managing the server environment, and handling the edge cases that arise with any hosted or on-premises software.
If you self-host 3CX, that responsibility sits with your internal IT team. If you use a cloud-hosted deployment through a reseller, the reseller handles it — but you are relying on their operational discipline rather than a dedicated provider whose sole product is keeping your phones working.
For businesses with a dedicated IT function, this overhead is manageable. For a ten-person company where the office manager also covers IT, it is a real cost, even when it is invisible until something goes wrong at 8am on a Monday.
Where 3CX genuinely wins
3CX has real strengths that are worth naming clearly.
Microsoft Teams integration. 3CX can act as a direct routing solution for Microsoft Teams, which means your Teams users can make and receive external calls through the 3CX platform. For organisations that run their business on Teams and want a single client for calls and collaboration, this is a meaningful advantage.
Integration breadth. 3CX integrates with a wide range of CRMs, helpdesks, and productivity tools. If you have a complex integration requirement, 3CX likely has a connector or a documented API path to get there.
Deployment flexibility. You can run 3CX on-premises, in a private cloud, or through a reseller's hosted environment. Organisations with specific data residency or network requirements have genuine options.
The free tier. For a small team with minimal call volume and no requirement for advanced features, the 3CX free tier is a legitimate option. It costs nothing and it works.
How VoIPninjas works
VoIPninjas is a hosted VoIP provider based in Christchurch, Dorset. There are no resellers. You buy directly from VoIPninjas, and support comes directly from VoIPninjas.
There is no server to manage. The platform is fully hosted. You access your configuration through the portal, and your phones register to the VoIPninjas platform over your internet connection. Adding a user, adjusting a ring group, or updating an auto-attendant does not require a call to a third party or a ticket to a reseller.
The target customer is a UK business that wants a reliable, managed phone system without the overhead of running it.
Pricing
3CX pricing is not published as a single transparent figure. The licence cost depends on the tier and the number of simultaneous calls. Hosting costs depend on the reseller. Support may be bundled or billed separately. The total varies by reseller, and you cannot compare like for like without requesting a quote.
VoIPninjas pricing is published and fixed:
- Ronin — £5.99 per user per month. 100 UK minutes. 28-day rolling.
- Samurai — £14.99 per user per month. Call recording, auto-attendant, ring groups, DDI, voicemail-to-email, mobile app, 750 UK minutes. 28-day rolling.
- Shogun — £24.99 per user per month. Everything in Samurai, plus unlimited UK calls and calls to 55 countries. 28-day rolling.
No setup fees. No annual commitments. No reseller margin added on top.
Contract terms
3CX licences are sold on annual terms. If your requirements change mid-year, you are still paying for the licence period you committed to.
VoIPninjas runs on 28-day rolling terms across every plan. You can scale up, scale down, or cancel with 28 days' notice. For growing businesses, seasonal businesses, or anyone who has previously been locked into a contract they could not exit, the distinction is real.
Complexity and who it suits
3CX is a powerful, configurable platform. It rewards expertise. If you have an IT team that understands SIP, is comfortable with configuration work, and wants granular control over how the system behaves, 3CX gives you that control. The flexibility is genuine.
The trade-off is that flexibility requires management. Features that need configuration need someone to configure them. Updates need someone to apply them. When something breaks, someone needs to diagnose and fix it.
VoIPninjas trades some of that configurability for simplicity. The features on each plan are ready to use without technical knowledge. An office manager can add a user or amend an auto-attendant message without involving a reseller or raising a support ticket. That is not a limitation — it is a deliberate design choice for businesses that do not want to think about their phone system.
Who should choose 3CX?
- Businesses with an IT team or a trusted IT partner prepared to manage the deployment
- Organisations running Microsoft Teams as their primary communications platform and wanting external calls routed through it
- Businesses with complex on-premises or hybrid infrastructure requirements
- Small teams with very light call volumes who are happy to use the free tier
Who should choose VoIPninjas?
- Businesses that want a direct relationship with their VoIP provider, with no layer in between
- Businesses without a dedicated IT function
- Teams that want to manage their own phone system without involving a reseller
- Anyone who wants to see the exact price before signing up
- Businesses that need 28-day rolling terms rather than annual licence commitments

Frequently asked questions
Is 3CX really free?
The 3CX free tier is genuinely free. It supports up to four simultaneous calls and includes core features. The limitations are the concurrent call cap and some restrictions at the free tier level. For a very small business with light call volume and no advanced requirements, it is a workable option. As requirements grow, you move to a paid licence, and the cost depends on your reseller.
Can I switch from 3CX to VoIPninjas?
Yes. VoIPninjas can port your existing numbers to the platform, and most businesses are live within ten working days. Your 3CX licence runs to its annual term, so it is worth timing your migration accordingly unless you are willing to absorb the remaining licence cost.
Does VoIPninjas integrate with Microsoft Teams?
VoIPninjas does not currently offer a native Microsoft Teams direct routing integration. If your business runs primarily on Teams and you want external calls to route through the Teams client, 3CX is better suited for that requirement.
What support do I get with VoIPninjas versus a 3CX reseller?
With VoIPninjas, support comes directly from VoIPninjas. There is no reseller in the chain and no third party to escalate to. With 3CX, your support relationship is with your reseller, who will have their own response times, escalation processes, and support hours. The quality of that support depends entirely on the reseller you have chosen.
