Telnyx CPaaS Reviews & Product Details

It’s very easy to use and simple to get started. We use two of their product offerings, and the system is intuitive and walks you through the setup, so you can get up and running quickly. Review collected by and hosted on G2.com.

I don’t really have anything bad to say so far. The only issue I ran into was with the AI voice—getting it to do certain things correctly. That may have had more to do with how the system was interpreting my prompts than anything else. It took a few tries to get it to do exactly what I wanted, but we eventually got there.

We’ve been using Telnyx extensively and what stands out most is the reliability and performance of the platform. It’s clearly built from the ground up rather than relying on third-party infrastructure, which shows in the call quality and consistency, especially at scale.

Pricing is also very competitive for the level of capability you get. Their APIs are flexible and well-documented, making it easy to build more advanced workflows without running into limitations.

Overall, it’s a robust, high-performance platform that gives you a lot more control compared to most CPaaS providers. Review collected by and hosted on G2.com.

There aren’t any major downsides we’ve run into. Review collected by and hosted on G2.com.

The portal UI is clean and well-designed, and the API documentation is comprehensive. Initial onboarding flow looks professional and gives confidence that the platform will work as advertised. Review collected by and hosted on G2.com.

The service was never delivered. I purchased a Brazilian local number on February 24, 2026. Documentation was approved, number showed as Active, TeXML app was correctly configured and not a single inbound call ever reached Telnyx's infrastructure. Confirmed in writing by their own NOC team after three weeks.

The support process is fundamentally broken: every agent requested fresh test call samples within 24-48 hours, then took days to respond at which point the logs had "expired" and the cycle restarted from scratch. I dealt with at least four different agents with zero continuity or resolution.

I switched to Twilio the same day I escalated. Brazilian number fully functional within 48 hours. Run away from Telnyx! Review collected by and hosted on G2.com.

My experience with Telnyx was that the API was very clear, and all the documentation was very well done. Review collected by and hosted on G2.com.

Have had no issues so far while trying to learn and use Telnyx. Review collected by and hosted on G2.com.

It was really easy to set up the SIP trunks between Telnyx and my session border controllers, and it was pretty straightforward setting up the failover. Review collected by and hosted on G2.com.

The account management could be a bit smoother (and it has gotten better lately) but I have so few problems that it doesn't impact my view of the company. Review collected by and hosted on G2.com.

The best part is how easy it is to get started. The documentation is clear and helpful, especially when building your own systems. The interfaces are simple to understand, and if something feels unclear, they provide ready-made examples you can copy and paste to an LLM . It makes it easy to develop and integrate your own solution without getting stuck. call and actully talkning is supper good no issue thier. Review collected by and hosted on G2.com.

The pricing can be a bit confusing at first, and it takes some time to understand the cost differences between their various services. A meeting with the sales team helped a lot, but the pricing could be easier to navigate from the start. Another thing that slows things down is the time it takes to get a fully validated number, especially in Sweden. Support does answer, but it can take a few days, which becomes noticeable when you are waiting for number verification to move forward. Review collected by and hosted on G2.com.

I’ve been using Telnyx CPaaS for quite a while, and what I like the most is how intuitive and reliable the platform is. The dashboard is clean, easy to navigate, and makes managing numbers, calls, and messages simple. The support team is outstanding, they always respond quickly, provide clear and helpful answers. The setup and integration process were smooth, and everything just works as expected. Review collected by and hosted on G2.com.

There’s honestly not much to dislike. Occasionally, documentation could go a bit deeper for some advanced features, but the support team makes up for it by providing quick and precise help whenever needed. Review collected by and hosted on G2.com.

The API seems well-documented, and the wireless SIM capabilities are great Review collected by and hosted on G2.com.

Telnyx does not have any meaningful support. My account was denied L2 verification, which is required to use the SMS API, and the only recourse given is to "contact support". I filled out the support contact me form, I called the support number on 4 different occasions, and I have yet to interact with an actual human. The support line rings and rings, until, after waiting on hold for 10-15 minutes, you are directed to a voicemail box where you can leave a message, which will not be returned. I have left three of them so far, with two different phone numbers to contact me at, and have never heard back, so, while I would like to use some of the APIs and features of Telnyx, I simply cannot since they will not verify my account and will not contact me regarding this.

I came accross Telnyx as a phone number provider. The whole process was straight forward, especially with obtaining numbers from Germany. To be honest it was the only platform which guided me without any obstacles through this process.

Lately I discovered that Telnyx has some out of the box AI solutions, their portfolio is growing constantly. The implementation of the AI Voice assistant through their widget is super smooth, the integration on my page worked immediately.

Recently I had a small problem, I used the embedded Chat Assistant which guided me through, so problem was solved within a few hours time. Review collected by and hosted on G2.com.

There is nothing that I would complain about. Review collected by and hosted on G2.com.

I am a QA engineer. I really like how easy it is to get US phone numbers for receiving inbound calls and SMS for our apps. The numbers work reliably. Also, I had a great experience with customer support when I had a top-up issue; they fixed it very fast. Review collected by and hosted on G2.com.

Recently, I faced a minor problem when trying to top up my account with my debit card. However, the Telnyx support team was very quick and helpful in resolving this, so it turned out to be a small issue. Review collected by and hosted on G2.com.
