Telnyx is amongst the best API’s my business has tested in the CPaaS sphere. The price per message is the lowest on the market and Telnyx’s continuous customer support meant I was quickly settled into the platform.

I reported a Telnyx customer running a student loan scam more than a month ago. The scammers are still active and still scamming. When I ask for status on the investigation, I simply get the run around. Come on Telnyx, you can do better. It doesn't take a rocket scientist to figure out who is running a scam on innocent people.

I was referred by a friend and Telnyx has been great so far. I have one major issue with it though, the API is properly set up to handle barges. I have reps that do outbound dialing and I can't listen to their calls I can't come in on their calls if they're not saying the right things that would get the sale. That's my only downfall but other than that it's been fantastic

Hey Mr. Hair! Thanks for the feedback! If I knew a bit more about your set up I could make the best recommendation but one easy thing anyone can do record calls and then listen to them for quality control and auditing purposes. Depending on your set up there are also ways to listen in on calls live that our tech support can possibly help you with. Thanks again for reaching out!

I've been using Telnyx for the past few months and it's been okay. When I created my account, I was told that I needed to send my identification to them, like many other providers do. That's fine, I do it and it happens. Then they move to a "new system" where I have to give my identification to them again. The only reason why I'm logging in is to pay my bill before I lose my services and to fix an issue, because my phone service which I PAID telnyx for isn't working. Annoyingly, I did it, even though they did who knows what with my ID before. Then they say my identification card isn't accepted. It's a Georgia (USA) Driver's License. I call their 24/7 support and they tell me that I need to do it again or E-mail their support, which a lot of times can take hours to get something resolved. I'm done with Telnyx at this point and I ask the agent can I port my number to another company. She says yes and that I need to sign-in to the portal to do it. I can't even sign in to the portal to use the products I am paying for. This is just shameful

Hi David, Mark Morse with the Customer Success team here at Telnyx. Trustpilot unfortunately does not give us much information other than your first name in this scenario so I have requested more information so I can look up your account where we can make this right and ensure we can get you up and running on the platform. Updates to follow as soon as we receive this information.

Telnyx was referred by a vendor setting up my phone system, and it has been great for us. Call quality has been great, and there has been no downtime so far. Features are easy to locate, and tech support staff (via chat) was quite helpful the one time it was needed, and was resolved in about 3 minutes.

Very useful service for me. I use hosted messaging, mainly, and I prefer the API to Twilio. I also appreciate the M2M SIM offering, and am using that for a 4G LTE modem for monitoring purposes. I had a number porting question, and they answered thoroughly and promptly. Great service.
