Designer

Nothing worked for me, so wasted of time and money, they make jokes about your problem, and blame other for they fraud.

Network Architect

Call forwarding as of yet does not work. They test calls from their system which is absolutely meaningless.

Sales Development Manager 

Very good software works perfectly in Mexico. Customer Support is great in different languages.

I use Zadarma PBX for more than a year. It's great and stable product, easy to config, with great prices and very good support service.

Wasted over a week just to verify one phone number. Overall incompetence and lack of responsibility.

Marketing Manager

Fails all the time, terrible customer support, they take your money and then ask.

Co founder

It's fast and easy to get any number I wanted. I am so far very happy with Zadarma and would recommend them to anyone looking for an online phone service.

Owner

They helped me with everything and after a few hours, our software was working perfectly.

Founder

Simple integration with top CRM systems. Great value for money compared to competitors.

Director

Poor customer service and difficult sign-up process.

Problems on their website - I starter registering a phone number but it didn't do that.

Currently our virtual number is never used as sender-id by Zadarma. The sender-id that is used currently is 'Zadarma.com', which looks very unprofessional to my customers.

There are several technical issues with PBX, such as lack of transfer functions integration with hardware and software phones.

Engineering Director 

Ease of use, works faultlessly. Looked for simplicity, found it here.

Very hard to find the recordings - it's not intuitive.

Senior product designer

Very easy to set up, we managed to do everything on our own.

manager

Easy to use,  exception installation and application. Moneywise is reasonable.

The price does not depend on the number of users, we are expanding rapidly and appreciate that we do not have to pay extra for each new employee.

IT Consultant

No idea how many calls were missed as a result. Call transfer between extension occasionally does not work.

President

Feature rich, price competitive, flexible... and best of all... fantastic support... questions always answered quickly and professionally.

owner

Very easy to set up - i am using FreePBX. Support has been great - answered my questions and pointed me in the right direction.

Partner

Overall I've had a great experience with them and have recommended them to others (I've heard great comments from others that switched as well).

I love the fact that they are really easy to setup and use. I use it more for personal use and absolutely love how I can stay in touch with my family for a fraction of the price.

IT Mgr

Very easy to set up and manage with good controls on use, coupled with great pricing and a very responsive support staff.

Pricing is the best in the market, very easy to set up and use. Support is eager to help you and get your working.

Owner IT

Its very nice to use and the pricing is nice since they use usage pricing. They have recently expanded to have more local numbers and free porting.

Been with voip.ms since 2010 and can't be more happy. The quality/price ratio is the best.

secretary

It is great that you don't need to purchase customized equipment to use VOIP.ms. Now with the self isolation it has been great to have the option to forward the phone numbers.

Great price, great quality, features, positive attitude from technical support.

Manager of Technology Services

They have a robust and reliable platform that is extremely easy to use.

member

However,  due to the time consuming and lack easy tools to block the spam and junk calls. I am seriously  considering  moving some of my numbers to Google or other mobile phone service providers.

Ease of use and great support. I will be using it for a while.

The registration of users is not always clear. Sometimes there is a problem, but I don't know all the technical terms to ask about the problem.

IT Manager

Something a heavy, costly, unstable Avaya PBX cannot do.

Chief cook & bottle washer

From installing my own voip gateway to configuration, I can set it up as I wish. The API is a big deal as well as it enabled us to write a SMS/MMS interface application that meets our specific needs.

Software eng.

You have control of everything, you can do exactly what you want. There is also API: very usefull.
