A block of numbers owned by Telnyx is harassing people with robocalls and unsolicited sales calls, despite many of us being registered with TPS and all of us telling them to go away. It's over the top, bombarding people with up to 5 nuisance calls a day. There's been many people reporting to who-called.co.uk and many including myself have lodged complaints to ICO, but nothing's happening. As I'd really like to find these a$$holes and shove their phones where the sun don't shine, I'm hoping perhaps this review will prompt some action by Telnyx to stop this harassing behaviour? The numbers used to harass me are 0116 483 0901 / 0915 / 0943 / 0947 / 0945 / 0243 / 0244 / 0245 / 0303 / 0801 / 0820. This is just a small sample of the total reported by everyone. See who-called.co.uk for the full set. Update 31st January: I'd like to thank Telnyx for the prompt response to my review. Updating rating from 1 to 3 stars in the hope that action will be taken. I have submitted the complaint with all numbers listed above plus today's harassing calls from 0305 & 0308. If this stops within the next couple of days I'll update to 5 stars.

Hi Anne, We take reports of our customers making unwanted calls very seriously. The quickest way to escalate is always to submit an Abuse report at https://telnyx.com/report-abuse which will go straight into our queue to be investigated and stopped. Thanks for reaching out!

I was able to integrate and test my custom application for my client's SMS sending needs in just a couple of days, thanks to a detailed API's documentation. Every single question that I asked was answered immediately in their online support chat. I will also consider other TELNYX products for my client's needs.

I signed up 3 days ago. I had an issue with my SIP account and it has been almost 48 hours without support. A terrible experience.
