Import Retell agent into Telnyx

29, Nov 2025

Telnyx now imports Retell agents directly into Voice AI Assistants. Teams keep their existing prompts and logic while gaining lower latency, consistent telephony, and clearer control of multi-step flows. This reduces operational issues that appear as traffic scales.

What’s new

  • Direct Retell import: Pulls prompts, tools, logic, and settings into Telnyx automatically.
  • Multi-assistant graphing: Splits Retell multi-prompt agents into modular connected assistants.
  • Integrated telephony path: Runs inference within the Telnyx voice stack to remove cross-cloud hops.
  • Single-provider routing: Uses Telnyx carrier infrastructure for call delivery and audio quality.
  • Immediate testing: Run live calls with transcripts, STT, TTS, and handoff visibility.

Why it matters

  • Reduces latency variation during high-volume traffic.
  • Improves call reliability by removing third-party carrier dependencies.
  • Simplifies multi-step logic by making branches explicit and maintainable.
  • Prevents hidden routing issues that are difficult to diagnose on external carriers.
  • Supports production workflows without rebuilding agent behavior.

Example use cases

  • High-volume outbound campaigns that require stable response times.
  • Multi-step qualification flows with scheduling or CRM lookups.
  • Inbound support lines that depend on consistent PSTN routing.
  • Regulated processes that need full visibility into call paths and logic transitions.

Getting started

  1. In Mission Control, open AI Assistants under AI Storage & Compute.
  2. Select Import assistant, choose Retell, and enter your Retell API key.
  3. Load your available Retell agents.
  4. Select the agents to migrate and create Telnyx-native assistants.
  5. Review the generated assistant graph, adjust handoffs if needed, and run a live test call.

Import your Retell agent now in your Mission Control Portal or contact your Telnyx team.
