What is a virtual PBX?

It's a phone system that runs in the provider's cloud instead of on hardware in your office. You configure calls, IVR, queues, recording and statistics through a browser-based panel, and you answer calls on a computer, an IP phone or a mobile app.

How much does a virtual PBX cost for a business?

In Poland, prices start at around PLN 25–49 per month for the PBX itself, plus the cost of calls or minute packages. At ACTIO, a virtual PBX costs from PLN 49/month, with no spending on hardware or a technician.

Will I keep my current business number when I switch to a virtual PBX?

Yes – numbers are ported under MNP with no interruption to service. We've covered the step-by-step migration in a separate guide.

Does a virtual PBX support remote work?

Yes – it's one of its biggest advantages. Employees log in to the PBX from anywhere using a computer or smartphone app, while the customer always calls the same company number.

Can you send SMS from a virtual PBX?

Not with most providers. At ACTIO, two-way SMS is integrated with the PBX – messages go out from the company number, and customer replies land back in the panel.

Virtual PBX Ranking 2026 – Comparison for Businesses

The on-premise PBX in the server room is becoming history. In 2026, businesses are choosing virtual PBX systems – cloud-based platforms that set up calls, queue them, greet callers with an IVR menu and integrate with a CRM, without a single cable in the office. We checked how the most popular providers available in Poland stack up in this market.

How we compared virtual PBX systems

We evaluated what actually matters for a company's day-to-day work:

call handling features – IVR (voice menu), call queuing, routing by business hours, call recording,
flexibility – number of extensions, mobile and desktop apps, remote work,
integrations – an open API, connecting with a CRM/ERP,
text communication – whether the PBX also handles SMS (rare, and increasingly a requirement),
billing model and support – predictable costs, technical support in the local language.

ACTIO – a PBX that calls and texts

ACTIO's virtual PBX is the only solution in this comparison where the company number handles both calls and two-way SMS – customers can reply to a text and call back on the same number, with everything landing in a single panel. On top of that, it offers a full set of call-handling features (IVR, call queuing, routing by business hours, recording), an open REST API for CRM/ERP integration, and a dedicated account manager instead of a helpline. ACTIO is a Polish operator registered with UKE with its own infrastructure – the PBX starts from PLN 49/month, with deployment in a few days and existing numbers kept (via MNP).

ZADARMA – the cheapest start, with everyday trade-offs

A zero subscription fee for the PBX is impressive and works well for a micro-business with low call volume. But you'll need to accept per-minute billing, paid call recording, a basic API and support limited to tickets – which can be painful if your company line goes down. No SMS support from the PBX.

FCN – a classic approach, solid foundations

A proven Polish player with a full set of voice features and phone support. Integrations are limited to the basics, with no SMS communication – a traditional "voice" PBX, priced similarly to ACTIO.

Halonet – decent foundations, notable gaps

A solid voice PBX at a low price, but a limited mobile app, no API and no SMS narrow it down to the simplest use cases. The "to be arranged" number of extensions makes it harder to compare offers.

SuperVoip – flexibility at a low price

The cheapest subscription in the comparison, with a full set of basic features. The trade-off is email-only support and basic integrations – a fit for companies that just need a "calling PBX" without expanding into other channels.

Which virtual PBX should you choose?

A micro-business with minimal call volume and a "PLN 0" budget – ZADARMA, if you can accept ticket-only support and per-minute billing.
A company that just needs voice – FCN or SuperVoip, depending on your priority: phone support or the lowest subscription.
A company that wants a single number for both calls and SMS, CRM integration, and Polish support with a dedicated account manager – ACTIO. It's the only PBX in this ranking that combines voice and two-way SMS, which makes the biggest practical difference in customer service (confirmations, reminders, replies).

Summary – virtual PBX systems in 2026

Basic voice features have become a commodity – IVR, queuing and call recording are now offered by every serious provider. The differences you actually notice after deployment are: channels beyond voice (SMS), integration quality (API) and support when something breaks. ACTIO comes out strongest in these three areas; ZADARMA competes on price, while FCN, Halonet and SuperVoip fill out the middle of the field.
