Very good service

Clear instructions for installation and configuration, clear explanation of charges, ease to configure and monitor. I am very happy I found them.

In 3/2026 as my Skype subscription ran out I chose to port my number to Zadarma. The process was fairly smooth and done in a few days. I needed to interact with their chat for help with the account activation, and response was very quick, they even called me to help with the final step. Communications were clear and friendly. They have a list of what they need, and as they're EU based there are some legal ID requirements they need to meet, but no problem (many reviews complain about this), they handle it great and automate it as much as possible. Call quality is good, and functionality options are very broad, so many tools I don't need, but would be handy for a business.

I was in a different country and had to call my bank. Zadarma service quickly and effectively solved the problem for me.

When I’m not in the office calls go directly to my mobile without anyone noticing. It keeps things professional and avoids missed leads. I also like that I can schedule time slots. It’s flexible and works exactly how I want. Simple but super useful.

Before using Zadarma our agents had to copy call details manually into our CRM. Now it’s automatic and error-free. It may sound small but it saves hours every week. You realize how useful it is once you stop doing things by hand. Worth every euro.

I opened a ticket and got a human reply in less than an hour. The agent didn’t sound robotic or scripted at all. They even followed up later to check if everything was still okay. That’s the kind of small detail that builds trust. Rare these days really.

I have been using Zadarma for a few years now. It is connected to my private asterisk server as a PSTN trunk with a local number. No problems or issues since then. Everything just works silently. Godd that the outgoing calls have correct CallerID in Europe. (I had a problem with another sip provider, broken CallerID after new regulations). Thanks, Zadarma (not an ad, real thanks)
