I’m a new Telnyx customer and so far things have been straightforward. The setup process was clear, and the support team answered my questions promptly.

Very well structured configuration menu and great knowledge base. Though it was my first time setting up a trunk, I managed to do it via the self help tools.

Telnyx has been working really well for me. I run an IT services business and have been testing out various VoIP/SIP providers. Telnyx stood out in a few ways. Call quality is excellent, and their system feels way more polished than some of the other options I looked at. One of the best parts for me is how easy it is to debug call issues using their SIP flow tool. That’s not something I’ve found with most other providers, and it saves me a ton of time. Their support team is also quick and helpful, especially via chat. I had a weird setup issue (totally my fault) and Nolan from their support walked me through it without any hassle. The only downsides for me are that it’s not the most intuitive for multi-client setups, and their documentation didn’t cover the specific use case I had (CloudUCM). But overall, I’m sticking with them. Good value, strong features, and solid support.

we have had a very great experience so far. The ease of setup, the self service portal, the innvoative features they provide for the cost is worth it compared to the competitions in the market. we are using telnyx for SIP trunks and voice numbers and we are happy with everything so far. their support is also quite responsive and available over the chat whenever needed.

The compliance process is a mess. And going thru in positively, I still couldn't use the service. Support did nothing to help. Shortly: day 1: uploading scan of my passport, rest of the details (Level 1 compliance auto-approved) at this stage I can't do anything. level 1 compliance says I should be able to buy local phone number but I couldn't. So I'm going thru level 2 compliance day 2: uploading pretty much the same documents, waiting day 3. level 2 approved. I can now buy a Polish number? no. I still need a separate compliance review per this action, uploading again the same documents day 4: they approved it. I buy a Polish number. I integrate telnyx to be used as carrier in Twilio BYOC. it doesn't work. All the calls are being rejected between far end and telnyx. Support unable to help. Lost a few days

Hi Krzysztof, Trustpilot doesn't give us any account-related information on their platform so I was unable to look up the ticket you are referring to. I have requested more information from you via the Trustpilot app so I can look up the ticket to provide more context to your feedback. Looking forward to hearing from you! Edit 5/5/25 Thank you for providing more information. After reviewing your referenced ticket ID 2154496 it looks like the reasons the call was failing was because you did not go through the process of CLI verification. Once you complete this, your calls should be going through with no issues. Please reach out if you have any other questions.

CHAOS. couldn't place calls to European countries, because I am a European country. Support was not able to give support > not solution oriented. They did not check the account... every question was answered evading the problem itself. After wasting my time for 6 hours, they said.. you need 2d level review on your account.... OK no problem. So I gave ALL DETAILS, passports, proof of address ... and the 2nd review was refused without any communication. This platform is US oriented, not ready or mature enough for the European market. After we closed the account we asked for a refund. Because they didn't respond we started a claim procedure with Paypal. Now they REFUSE to refund because we started a claim, and they state that they are not able to refund because we started a PayPal claim. Another lie from this company. If they do not respond to the claim, PayPal will eventually indeed intervene. This company has insufficiently trained staff /unmotivated supports staff ... and the whole company operates in complete CHAOS!

As a solo developer running my own app-based business, Telnyx has been a game-changer. I use their CPaaS platform mainly for SMS and voice features in my apps. The setup took a bit of effort at first, but once everything was in place, it ran smoothly and reliably. I appreciate the transparent pricing, the responsive support, and the level of control I get through their dashboard and APIs. It's helped me deliver a more professional and scalable product without needing to invest in heavy telecom infrastructure.
