"Transcript Search Saves Time and Powers Better Coaching"
5/5
What do you like best about Zadarma Cloud PBX?

Being able to search transcripts saves us a lot of time versus listening through entire call recordings. We rely on them to spot recurring issues, such as missed compliance phrases, weak openings, and repeated customer complaints. We also put together small libraries of “good calls” and “calls to improve,” and then use those examples during coaching sessions. Review collected by and hosted on G2.com.

What do you dislike about Zadarma Cloud PBX?

Transcription minutes are limited, so we have to be selective about which calls we choose to transcribe. Review collected by and hosted on G2.com.

"Reliable for International Calls – Great Mobile App, Some Desktop Issues"
4/5
What do you like best about Zadarma Cloud PBX?

Zadarma is a solid VoIP solution that I primarily use for international calls. The call quality is excellent, and the pricing is very reasonable. I especially appreciate how smooth the experience is on my phone — both incoming and outgoing calls work flawlessly. Review collected by and hosted on G2.com.

What do you dislike about Zadarma Cloud PBX?

The Mac desktop app is less reliable. Occasionally, calls just don’t go through, which is frustrating when I need to make a quick call from my laptop. Also, I receive some spam messages — not sure if it’s the app or just the number I’ve been assigned, but it’s worth noting. Review collected by and hosted on G2.com.

"Good variety of numbers, Terrible service"
1/5
What do you like best about Zadarma Cloud PBX?

PBX admin panel is decent, good variety of international numbers are available. Review collected by and hosted on G2.com.

What do you dislike about Zadarma Cloud PBX?

After being a customer for many years I have received a request for verification stating that I need to upload a copy of my passport and until I do none of my numbers are functioning and balance can't be topped up. I have completed verification in a timely manner, but account is still offline. During this period none of the incoming phone calls are routing to our numbers. I have been a loyal customer for over 7 years and never had any issues with your service. What's going on and why you make it impossible to use the service during the verification process? I am also especially concerned with the number expiring soon that we are unable to top up balance for. If it expires - how can we get this number back? We have invested our advertising budget into this and can't understand how such business practices can be the thing of today without regard to customer's needs, especially in the busiest time of the retail sales season! Additionally our Ukrainian number have not been working for weeks and no resolution or explanation has been provided. Review collected by and hosted on G2.com.

"I have been with Zadarma Over 10 years"
3/5
What do you like best about Zadarma Cloud PBX?

I like the fact that it is a fully robust PBX and it can be tailored to basically all of my needs Review collected by and hosted on G2.com.

What do you dislike about Zadarma Cloud PBX?

Since its inception, the PBX is so unwieldy and requires an IT guy in house to deal with it - or requires tech support from Zadarma to help me configure it - and Zadarma flat out has the worst possible customer support and tech support of any entity on planet earth as far as my experience has proven even to this very day.

"A great find for my business"
5/5
What do you like best about Zadarma Cloud PBX?

Feedback is gratitude. The possibilities of this service saved me as a business beginner. The service was recommended by friends who have been using Zadarma for more than 3 years. I am engaged in online sales, the team consists of a couple of operators who communicate with customers. I began to notice that there were more missed calls than successful answers in the statistics. First, I set up CRM - the fact that it is free, a separate help in the development of my own business. It has become easier to understand which customers have several purchases and which are newbies. Then I read on their blog about conversation analytics, decided to try it - that's where my problem was found. It turns out that one of the operators allowed himself to violate the tone of voice of the company, which led to the creation of a negative opinion about my business. I heartily recommend it.

What do you dislike about Zadarma Cloud PBX?

I did not find any negatives for myself at all Review collected by and hosted on G2.com.

"Great tool"
5/5
What do you like best about Zadarma Cloud PBX?

There was a need to quickly deploy multi-channel communications that are available on mobile phones. The Zadarma service turned out to be the most adequate in terms of cost, quality and range of services provided. In just a few hours we did everything necessary - connected an 800 number and set up a voice menu + forwarding. Everything works, everyone is happy. Review collected by and hosted on G2.com.

What do you dislike about Zadarma Cloud PBX?

We didn’t find an integration with our CRM at that moment, but they have done it by now Review collected by and hosted on G2.com.

"Zadarma has solved my issue"
4/5
What do you like best about Zadarma Cloud PBX?

I used to forget to return calls, forget who called or what it was about so often, I turned to Zadarma to solve this. And it did.

My call logs and voice recordings mean if I forgot something, I could go back and get an accurate copy of the event.

No more missed opportunities! Review collected by and hosted on G2.com.

What do you dislike about Zadarma Cloud PBX?

I must admit, there was a bit of effort needed to set it up. As I'm unfamiliar with this sort of thing, the step-by-step guide was a little different to the actual setup. So I went around in circles for awhile. But both my CRM and Zadarma support helped me get it connected. Review collected by and hosted on G2.com.

The callback widget that we can put on our website is really good. Review collected by and hosted on G2.com.

What do you dislike about Zadarma Cloud PBX?
