We saw many teams prototyping with Retell and then running into the same issues once they tried to scale: variable latency, limited visibility into call failures, and telephony behavior that depends on whichever carrier sits underneath Retell.

Multi-step flows also get hard to maintain because everything lives in one prompt tree.

We built a way to import Retell agents into Telnyx so teams can test the same logic on a different infrastructure. You connect your Retell account, pull your agents, and Telnyx converts them into native assistants. Multi-prompt agents get split into separate components with clear handoff logic.

Most teams who try this mainly want to compare latency, barge-in behavior, and debugging visibility. Since Telnyx runs telephony, STT, LLMs, and TTS in the same PoP, the audio loop stays short, which tends to matter once real callers get involved.

If anyone here has experience moving voice agents between platforms or running into infra bottlenecks in Retell, I would be interested in hearing what problems you saw.
