Telnyx CPaaS Reviews & Product Details

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.

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.

The best part about Telnyx is the quality of their technical support. We were implementing their WebRTC JS SDK for in-browser calling, and their team was instrumental in getting us past a major roadblock. The support staff are not just reading from a script; they are technically proficient and can provide specific, actionable solutions quickly. Their API is robust, but it's the support that makes it usable. Review collected by and hosted on G2.com.

The primary challenge was that some of the public-facing documentation and CDN links for the WebRTC SDK were outdated. This led to a lot of initial frustration and wasted time trying to debug a ReferenceError that was ultimately caused by a broken link. Improving documentation maintenance would make the initial developer experience much smoother. Review collected by and hosted on G2.com.

I appreciate Telnyx CPaaS for being the only provider offering Swedish numbers with both voice and texting capabilities, all in one package, which I couldn't find with other providers. This feature is incredibly valuable to me as it allows my AI chatbot to connect to a Swedish number, giving it a professional appearance. I also admire how Telnyx CPaaS is very careful with preventing scammers on their platform, which increases my trust in their services. Additionally, setting up Telnyx CPaaS was super easy, making the initial experience smooth and hassle-free. The availability of the specific features I needed, such as the Swedish number, was crucial since no other vendor offered what Telnyx CPaaS did, leading me to choose them as my provider. Furthermore, if Telnyx CPaaS continues to work efficiently and allows me to just set it and forget it, I would certainly choose to buy it again. Lastly, I am highly satisfied with the service, rating it a perfect ten, as it has truly met my expectations. Review collected by and hosted on G2.com.

Nothing i can think of really Review collected by and hosted on G2.com.

The first time I registered with Telnyx, I immediately tried the AI ​​Assistant. I didn't expect Telnyx's AI assistant to produce assistance agents that closely resembled real humans. Furthermore, there are many models to choose from, ranging from those that connect directly to Telnyx or via API. It also includes connections to other voice providers like elevenlabs, though I'm still experimenting with Telnyx's voices. Review collected by and hosted on G2.com.

At first, I had difficulty accessing the usage history for each test call I made with the AI ​​Assistant. It was a bit tricky to find. It took a bit of effort for a beginner like me. However, the assistance provided by agent Aatif in the chat box was very helpful. Review collected by and hosted on G2.com.

Really good value services. I'm pairing a SIP trunk with Unifi Talk and have been really impressed by the cost and simplicity of set up.

I've had quite a lot of conversations with support and they are always responsive and helpful. Review collected by and hosted on G2.com.

I had some initial issues with an inbound number and it took longer than expected to resolve the problem but this seems to be mainly an issue with the upstream provider. Communication around this could have been better at the beginning but after a conversation things improved and I had daily updates until the resolution Review collected by and hosted on G2.com.
