Reliable Service and Quick Support for QA Needs

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.

Affordable VoIP with Excellent Call Quality and SIP Debugging

Having tried several other VoIP application providers, I find Telnyx stands out for being more affordable, delivering solid call quality, and offering outstanding SIP debugging tools. When I faced challenges integrating an external SIP server, the SIP debugging features available right from their dashboard allowed me to clearly follow each step of the call flow, which was extremely helpful.

What is Telnyx?

Telnyx is the only real-time conversational AI platform that runs voice agents on its own private global IP network and GPU-accelerated edge - not rented infrastructure. That ownership is what delivers true low latency from model to microphone, so agents respond in real time and sound human, not robotic. Everything lives on one platform: speech-to-text, text-to-speech, LLMs, and direct PSTN connectivity. An open, modular model approach lets you bring your own LLM or choose from a built-in library, then swap, fine-tune, or chain models to optimize cost, latency, and performance - with no lock-in. Whether you're enhancing customer support, automating outbound calls, or embedding voice AI into your product, Telnyx gives you the infrastructure, flexibility, and 24/7 in-house support to launch and scale globally with confidence.
