Zadarma

What is Zadarma?

Zadarma is a cloud phone system that gives businesses virtual phone numbers in a wide range of countries along with a free cloud PBX to manage how calls are routed, answered and recorded. Instead of installing physical phone lines, a business sets up numbers and extensions in the cloud and makes or takes calls from a browser, a mobile app, or a compatible VoIP device. The combination of broad country coverage and a genuinely free PBX layer makes it a common choice for small businesses that want to look and sound local in markets where they don’t have a physical office.

Key features

• International virtual numbers. Get phone numbers in many countries to give customers a local number to call.
• Free cloud PBX. Set up extensions, call routing, voicemail and IVR menus without a paid base plan.
• Web and mobile apps. Make and receive calls without a desk phone, from wherever the team is working.
• Call recording. Record calls for training, quality checks or dispute resolution.
• CRM and helpdesk integrations. Connect call data to the tools a support or sales team already uses.
• SIP support. Businesses with existing VoIP hardware or software can connect it directly.

How to get started

1. Sign up at zadarma.com and set up your free cloud PBX.
2. Choose and purchase virtual numbers for the countries you want to reach.
3. Configure extensions, call routing rules and voicemail or IVR menus.
4. Connect the web or mobile app, or link a compatible SIP device.
5. Set up any CRM or helpdesk integration to keep call records with customer data.

Who Zadarma is for

Zadarma fits small and mid-sized businesses that want to expand into new markets without opening a physical office there, since a local virtual number goes a long way toward looking established to customers in that country. It also suits remote and distributed teams that need one shared phone system instead of everyone using personal numbers, and any business that wants call routing and voicemail set up without paying for the PBX layer itself.

Tips for setting it up well

• Put your number where people will actually use it. A QR code linking to a click-to-call number works well on business cards, invoices or a storefront window.
• Check a number’s reputation before relying on it for outbound calls. Tools like WHOIS lookup can help when verifying domains tied to your business identity alongside your phone presence.
• Start with simple routing. A basic “ring this extension, then fall back to voicemail” rule is easier to manage than a complex IVR menu until call volume justifies it.
• Test call quality on your actual internet connection before rolling it out to a whole team, since VoIP quality depends on a stable connection.

Zadarma vs alternatives

Unitalk is the more direct comparison for businesses focused specifically on the Ukrainian and regional market, with deeper local CRM integrations and voice bot features, while Zadarma’s strength is broader international number coverage and a genuinely free PBX. For businesses that want their phone system’s call data flowing automatically into spreadsheets, marketing tools or notification workflows, automation platforms like n8n or Make can connect to Zadarma’s integrations to move that data further.

Is Zadarma worth it?

For a small business testing a new market, or a distributed team that just needs a shared phone system without buying hardware, Zadarma is a low-risk way to start: the PBX itself costs nothing, so the only real commitment is paying for the numbers and calls you actually use. The interface can feel like more than a one-person business needs at first, but the free tier is generous enough to try it properly before deciding whether the paid calling and number options are worth adding.
