Affordable for non‑profits and charities

Running a charity means every dollar counts, and paying for expensive telecom services isn’t an option. Zadarma offered us nonprofit pricing, yet the system still delivers professional features like IVR, voicemail‑to‑email and call recording. Donors and partners often comment on how polished our communications are. It helps us appear established even though we operate on a tight budget.

Unified dashboard for multiple locations

We have offices in Madrid and Berlin, and we wanted one phone system that felt cohesive. Zadarma lets us manage both locations from a single dashboard, while local numbers ring the correct office first. If no one picks up, calls roll to the other office or to the mobile of the person on duty. It feels like one connected organization despite the distance.

Integrating with Zendesk improved tickets

Our support team uses Zendesk, and connecting Zadarma means incoming calls automatically create or attach to tickets. Agents see the caller’s history, notes and previous recordings without leaving Zendesk, which speeds up resolution. Follow‑up calls also log automatically, so there’s no duplication or confusion. The integration has streamlined our support workflow significantly.

Do not use this company!

Do not use this company — they collect your personal data, including passports, but never approve your accounts. When asked how this personal data is being used, they simply ignore requests and close the chat.
Unfortunately for them, we are an international law firm, and we will be proceeding with legal action in both the EU and the USA against these shady practices.

We understand your concern. Please note that activation of phone numbers is strictly regulated, and verification requirements are set by local legislation. Without completing this process, unfortunately, we cannot provide the service.
As soon as you requested a refund, it was immediately initiated. You can also delete your account together with all personal data at any time.

Perfect for live events

During virtual conferences and webinars, we need a temporany hotline to answer attendee questions. With Zadarma, we set up a dedicated number in minutes, route calls to volunteers, and record conversations for quality control. After the event, we disable the number, so it doesn’t clutter our main phone system. It’s a flexible solution that has become part of our event toolkit.

Great for small e‑commerce operations

We started our online store out of our apartment and used personal phones for customer service. Zadarma gave us a professional central number, call routing, and voicemails that forward to our support inbox. Now, customers get quick responses, and our personal lines stay free for family and friends. We look bigger than we are, and it didn’t cost a lot to get started.

Can't use if you vacation outside the UK

I tried to set up an account today with Maksym. I am a British citizen who lives in the UK, but I have been told that I can't use this service when vacationing outside the UK, as OFCOM forbids it!! This obviously isn't true, as so many other companies offer this service. Skip this company to find one that provides a seamless international cloud service.

OFCOM doesn’t ban British people making calls in the UK from other countries. You have taken guidance to an extreme conclusion!

Thank you for your feedback. We understand that this limitation may feel inconvenient, especially when travelling. However, UK telecom regulations – including Ofcom’s guidance on how UK phone numbers may be used – place certain restrictions on how outbound calls from UK numbers can be made when the user is located abroad.

Time-based call routing is a game-changer

We have different teams covering different hours, and before Zadarma, someone always forgot to change the call routing manually. Now, calls automatically route to the appropriate person during business hours, lunch breaks or after hours. We also change routing easily for holidays or special events. It’s one less thing to remember and prevents calls from falling through the cracks.

Detailed call history resolved a dispute

A client claimed they’d been ignored and threatened to take their business elsewhere. We pulled up the call logs and recordings from Zadarma, which showed our consultant called twice and left a detailed voicemail with times and dates. Sharing this information diffused the situation instantly. Having that level of transparency protected our reputation and kept the client relationship intact.

Unprofessional Support, No Accountability – Avoid for Business Use

We have been experiencing a critical audio dropout issue with our Zadarma number for weeks. Calls made through LiveAgent with Zadarma SIP consistently lose audio after 90–120 seconds, while calls via Zadarma’s own app work fine.

The problem has caused serious business interruptions during peak sales season. Unfortunately, Zadarma’s support has been nothing but an endless back-and-forth. Their team repeatedly insists the issue is “not on their side” and pushes us to LiveAgent. LiveAgent engineers, however, reviewed their side thoroughly and even provided technical evidence indicating the problem is in Zadarma’s routing or media handling.

Making matters worse, Zadarma refuses to work directly with the other party to solve the problem. They will not even provide an email where debug logs could be sent for faster, engineer-to-engineer communication. Instead, we are forced to act as middlemen between two providers — a process that wastes time and delivers no progress.

For a VoIP provider, this lack of accountability and professionalism is unacceptable. If your business depends on reliable, enterprise-grade voice service, I cannot recommend Zadarma.

We are sorry to hear about the difficulties you’ve faced. According to our system checks, calls made directly through Zadarma services are functioning correctly without audio issues. The interruptions appear only when using the third-party integration, which unfortunately we cannot influence or resolve on our side.

We kindly recommend continuing to work with the support team of the third-party service to address the issue. Our platform remains stable when used directly, and we will gladly assist with any questions related to Zadarma services.

Fast number porting without downtime

We were nervous about moving our main hotline from a legacy carrier because even a short disruption would have been costly. Zadarma handled the porting process efficiently, communicated with us throughout, and the number switched over seamlessly at the scheduled time. There was no interruption to service, and we didn’t have to chase anyone for updates. I was impressed with how smooth it was.

Conference calling made simple

We host frequent conference calls with clients and partners, and setting up a conference bridge used to involve clunky services with separate logins. Now, I create a bridge in a couple of clicks and send participants a PIN, and that’s it. I control muting and recording from the dashboard, and the call quality is consistently clear. It’s professional without being complicated.

Multiple device support is seamless

I work in different environments throughout the week, moving between a desk phone at the office, a laptop at home, and the mobile app on the go. Zadarma rings all my devices simultaneously, and whichever one I answer on takes over the call without hiccups. It’s genuinely seamless, which means I never worry about missing important calls. For a hybrid work model, that’s invaluable.

Call queues handle busy times

During product launches, our support lines can get flooded, which used to result in missed calls and frustrated customers. With Zadarma’s call queue, callers hear their position in line and are offered the option to request a callback instead of waiting on hold indefinitely. This transparency reduces frustration, and we call people back in the order they came in. We’ve seen a sharp drop in abandoned calls and happier customers during peak times.

Call scheduling keeps my evenings free

I run a small law firm, and clients often call after hours with non-urgent questions, which used to interrupt family time. Now, Zadarma routes calls to voicemail after 6 p.m. and sends me a transcript, so I review messages when I’m ready. Clients still feel hears because they can leave a detailed message, and I maintain work‑life balance. It’s a smart solution that respects both my time and my clients’ needs.

Saved money on international calls

We often call suppliers in China and Brazil, and our previous provider charged steep per‑minute rates. Zadarma’s international packages significantly lowered those costs, and we’re now calling overseas partners more often because the price isn’t a deterrent. It’s a simple change, but over the course of a year, the savings have been substantial. Better communication has also improved our relationships with those vendors.

The entire experience from start to…

The company’s reply didn’t acknowledge or respond to the main pain points stated in my review.

-
The entire experience from start to finish was horrible. Their customer service reps are lifeless, and at times rude and condescending.

Both numbers I purchased were already flagged as “scam” before I even used them. (Other services I’ve used never had this issue.) When the first number was flagged, I requested a replacement. Instead of simply helping, support asked why I waited a week to report it — even though I wasn’t using that number as caller ID, I was using my own until the system stopped working with my number. So then I started using the number I'd purchased from them only the day before. All of this was documented in the support chats, but they clearly didn’t bother to read.

The second number I purchased was also flagged as a scam on people's caller ID. I tried to overlook it, but then I was suddenly asked for ID verification — seemingly as punishment for requesting the first replacement. I submitted both my driver’s license (with address redacted) and my Texas Attorney General Address Protection card (my legal address). Both were rejected with no explanation, and they never even addressed why my account was flagged in the first place.

In the meantime, I wasted hours paying my assistants while the account was blocked. After investing all that setup time, it ended up being a complete waste of time and resources. I do not recommend working with this company.

Remote team coordination improved

Our SDRs are in three different time zones, and before Zadarma, returning call was chaotic if the original rep was offline. With call recordings and easy call transfer, if a prospect calls back, any colleague can review the last conversation in seconds and pick up where it left off. It makes our team feel like we’re all in the same office despite the distance. The continuity improves the customer experience and has boosted our conversion rate.

Works perfectly with Pipedrive

Our sales team lives in Pipedrive, and being able to click a lead’s phone number and call instantly has been a game‑changer. Calls automatically log with notes and recordings, so everyone stays on the same page and we avoid missing details during handovers. Managers can pull up recordings for coaching without digging through multiple systems. It’s streamlined our workflow, giving us more time to focus on actual selling.
