Analysis of the VoIP services market for companies: ACTIO vs ZADARMA vs FCN vs Halonet vs SuperVoip
Compared to traditional VoIP telephony, it means lower costs, greater flexibility and access to advanced features such as virtual PBX, integration with company systems (CRM, Service Panels), VoIP mobile numbers or mass SMS sending. Choosing the right IP telephony operator in 2026 is a strategic decision for any company. The market is saturated with many solutions, but only a few providers are able to offer full synergy between fixed and mobile services.

The ability to receive and send SMS via VoIP is becoming a game changer. In the following article, we will take a look at the five key players ZADARMA, FCN, Halonet, SuperVoip and the dynamically developing ACTIO brand. They differ in their offer, billing model and scope of services. Below you will find a reliable comparison – without spilling water.

Actio – Comprehensive Solutions for B2B Businesses
ACTIO is a Polish VoIP provider focused on the B2B market. It stands out for its low call rates (starting at 0.08 PLN/min for mobile phones) and the only comprehensive offering of +48 virtual mobile numbers that support SMS. A dedicated account manager and an open REST API enabling integration with CRM and ERP systems make it the platform of choice for companies seeking to digitize their communications. The absence of long-term contracts is an added bonus for companies that value flexibility.
ZADARMA – the most affordable PBX system, global coverage
ZADARMA, a company based in Bulgaria, attracts customers with its zero-subscription fee for the PBX system, which is ideal for micro-businesses with very low call volume. It offers a wide range of phone numbers from over 60 countries and relatively low per-minute rates. However, for Polish businesses, the lack of Polish VoIP mobile numbers and support limited to a ticket system can be a barrier; in the event of a company line failure, this can paralyze sales. The lack of native language support and a first-touch response significantly undermines trust.
FCN – a proven player with a classic approach
FCN is one of the oldest VoIP providers in Poland. It offers a robust infrastructure and telephone support, but requires a contract (usually for 12 months) and is priced above average. The lack of advanced SMS features and virtual mobile numbers makes it a less cost-effective and functional solution for modern, dynamic businesses.
Halonet – solid foundations, limited SMS/mobile offerings
Halonet offers a decent VoIP PBX and SIP trunk, but it does not include an SMS API or virtual mobile numbers. It is a good choice as a basic IP telephony provider for businesses that do not need advanced digital features and limit themselves to voice-only services with no plans to use SMS.
SuperVoip – flexibility at an affordable price
SuperVoip attracts users with its low entry barrier and lack of contracts. However, its offerings are limited when it comes to SMS and mobile numbers, and technical support is primarily provided via email. A good choice for small businesses or as a backup SIP trunk.

Summary — VoIP Telephony for Businesses in 2026
Choosing a VoIP provider for your business isn’t just about the price per minute. What matters is the comprehensiveness of the package (PBX + phone number + SIP trunk + SMS + mobile service all in one place), the quality of technical support, and the ability to integrate with IT systems.
If you’re looking for a single provider to handle all your business communications—from a virtual PBX and SIP trunking to virtual mobile numbers and an SMS API—with reliable support and an SLA, ACTIO, as a Polish B2B operator, comes out on top in this comparison. For companies with a limited budget and fewer requirements, it’s worth considering ZADARMA or SuperVoip.
FAQ — Frequently Asked Questions About VoIP for Businesses
❓ How does a SIP trunk differ from a virtual PBX? A SIP trunk is a voice connection linked to your own PBX (e.g., Asterisk, 3CX). A virtual PBX is a cloud-hosted service—you don’t need your own server.
❓ Does a virtual VoIP mobile number work like a regular +48 number? Yes—the number appears to the recipient as a standard mobile number. You can receive and make calls and send and receive text messages over the internet, without a SIM card.
❓ Why are SLAs and dedicated account managers important in VoIP? Choosing a provider that offers a service level agreement (SLA) and a dedicated account manager is, above all, an investment in security and business continuity. An SLA is a formal commitment by the provider to maintain service availability at a specified level; the absence of such provisions in pay-per-use models can mean longer restoration times in the event of an outage.
❓ Can I port my number to a VoIP provider? Yes, most providers on this list support landline number porting. Porting mobile numbers to VoIP depends on the provider.
❓ How much does business VoIP cost per month? Costs depend on the number of users, phone numbers, and voice traffic. For a small business (5–10 users), the monthly cost is typically PLN 100–400 net, with significantly more features than a traditional PBX system.
❓ Is VoIP secure for businesses? Yes, if the provider uses TLS/SRTP encryption and has protection against SIP attacks (fraud detection). Check for these features before choosing a provider.
