"Polished UX for Building Autonomous AI Call Agents with Twilio & Telnyx Integrations"

5/5

What do you like best about Retell AI?

It’s fairly straightforward to build an autonomous AI phone-call agent, including real-time function calling and call transfers. I’m also impressed by the flow-building UX; it feels polished and easy to work with, especially thanks to features like batch calling and integrations with Twilio and Telnyx.

What problems is Retell AI solving and how is that benefiting you?

Retell AI is solving some of the key edge problems in voice AI, such as latency, unnatural pauses, and low reliability. Since we use calling agents for several use cases, it works great for us. Now it feels like we’re talking to a real human sitting behind the call, not a bot. Also, with the use of voice mapping, it’s easier to sound like a real person based on different geographic locations and the tones people use there. Review collected by and hosted on G2.com.
