VoIPstudio (voipstudio.com) has a 4.4 out of 5 rating on OK.one, based on 100 user reviews collected here. It is listed under Electronics & Technology and its reputation is good. 85% of reviews are 4 stars or higher and 9% are 1 star; The business has replied to 82% of negative reviews; 35 of them were added in the last 12 months. Last updated 2026-08-10.
The setup process for this service is completely impractical for professional use. I paid for a subscription specifically to set up call diversion, but because my outgoing calls are blocked by an Anonymous caller ID, I cannot contact my customers. Businesses simply do not take calls from private or anonymous numbers seriously.
To make matters worse, I was asked to provide SIM card ownership documents after payment to fix this, which I am still waiting to receive from my carrier. In the meantime, I am stuck paying for a completely unusable service.
Taking payment without clear upfront notice about document requirements—and leaving customers with an anonymous outgoing caller ID that prevents them from doing business—is completely unprofessional. You need to streamline this verification process and resolve these restriction issues immediately.

Hi Kokila, thank you for leaving us a review!
We saw you'd been in touch with our support team, but it looks like we didn't hear back from you after that. Our team has since reached out again and would love to help get everything sorted for you.
If things are resolved now, we'd really appreciate you updating your review to reflect that.
Many thanks,

Exactly what I expected. Some hiccups setting it all up, but was able to watch some videos and figure it all out. No surprises, steady and reliable.

Hi Adam,
Thanks for leaving your review. I'm grateful for your positive view of the platform, but I'm very sorry to learn about your issue. We do pride ourselves on our high levels of customer service and platform reliability, which I know is little help if you've personally experienced a problem.
We would love to take the opportunity to address this, primarily to ensure you have a fully working service from end-to-end, but also to ensure you come away from the experience with a 5-star feeling.
Thankfully, VoIP has been a reliable technology for many years now, but we are aware that issues outside our control can sometimes impact experience. Nonetheless, even if an issue occurs outside our platform and network, we still always do our best to help fix it or advise on resolution.
I've sent you a private request via Trustpilot for some additional information, so if you would be able to share your account info confidentially, I would appreciate it. With this information, we will escalate your concern to the highest level internally, investigate further, and then reach out to you and help you resolve whatever may be causing this particular issue.
Many thanks for choosing VoIPstudio and I hope you'll give us the opportunity to help further.
Thanks,
VoIPstudio Team

We’ve now been experiencing a major…
We’ve now been experiencing a major outage with VoIPstudio for nearly 12 hours, and the most concerning part isn’t just the downtime; it’s the complete lack of communication.
We’ve attempted to contact support through multiple channels, including email and social media, and have received absolutely no response. For a company that promotes a 99.9% uptime SLA, this level of silence during a critical outage is extremely disappointing.
Our business relies on this service for day-to-day operations, and being left without any update, ETA, or acknowledgment puts us in a very difficult position. At this point, even a basic status update would go a long way.
Right now, it’s unclear whether this is a technical failure, a wider outage, or something more serious. The absence of communication is damaging trust far more than the outage itself.
We need transparency, timely updates, and a clear plan for resolution. Until then, it’s hard to have confidence in the reliability of this service.

Hi Mark, apologies for the issue, and I hope you received my reply via LinkedIn earlier, as well as from Chris through your support ticket.
As mentioned in my message, our engineers identified a routing misconfiguration made by one of our upstream carrier partners which has affected a small range of our numbers, which unfortunately affects your service.
We have a team working with our carrier to restore service ASAP, but I completely understand the inconvenience this causes and I'm also sorry our communication was not faster in this case.
Sincere apologies again. We'll keep you updated on our usual support channels with updates and/or resolution.
We do pride ourselves on great support and normally excellent uptime, but I know this will be of little help while you experience problems.
Many thanks for your patience and understanding. We'll keep you updated through your support ticket and email.

After creating support ticket, instead of replying they closed the ticket and deleate account without any reason
Reply from VoIPstudio2026-04-13
Hi,
As you are aware, we did share the reason for account closure with you.
However, as you have decided to make your case public, I would like to use the opportunity to advise that we take our responsibility to protect the public, as well as our obligations to regulators and law enforcement bodies, seriously as a global provider.
Indeed, we are often required to reject applications, terminate accounts, block calls, or sometimes even pass information onto these organisations when lawfully requested or when we detect abnormal usage or call patterns that do not indicate "normal use" of a communications system. We also request documents to approve legitimate requests and use of the platform for lawful or regulated business purposes, but these are not always forthcoming.
Occasionally, when escalated, information about requests and usage can also be shared by those authorities with other carriers and service providers, which can have a longer-term effect on obtaining or retaining service in the future.
This information is provided as general advice, but perhaps it may help explain why service withdrawals, terminations, or disruptions occasionally happen.
As this review is live and defamatory in nature, I will assume that you would like us to take this matter further and begin an official investigation. This could potentially involve those aforementioned 3rd parties, who may in turn lawfully request confidential information about account signup, payment and location, if suspicious activity is detected and a case is pursued.
Thanks,
VoIPstudio Team

Quality phone service with professional management. Everything works as expected. Great customer service. I'm an individual, not a company, and my international telephone needs are low level, but that makes no difference. Recently, I experienced a technical issue with the softphone app, and a service technician spent as much time as was necessary to address the problem. Great Service!
