Now you can use our analytics dashboard to monitor the performance of Voice AI Agents:

• Monitor key metrics like call success rate, transfer rate, call counts, and latency variations...etc
• Compare A/B test results across different agents.
• Create custom charts tailored to your needs.

This feature will be available for free starting early next week!

Telnyx Integration

You can now purchase Telnyx phone numbers directly on our platform.

Due to recent restrictions on Retell’s Twilio numbers, we’ve implemented a manual fallback. If you need a specific local number, you can purchase a Telnyx number for seamless outbound calling.

Import/Export Agents

You can now export and import any agent to your different organizations.

Export Call History Data

Export the complete call history using the selected filters and column settings, mirroring the call history table.

Bug fixes and improvements

1. New Voices for OpenAI Realtime: openai-Ash, openai-Coral, openai-Sage

2. LLM and TTS Fallback for individual calls

  • Now if the provider is up, but two consecutive failed utterance will trigger a fallback within individual calls.

3. LLM deprecation & upgrade:

  • claude 3 haiku will be deprecated, and all agents using that will be upgraded to claude 3.5 haiku;
  • claude 3.5 sonnet will soon be upgraded to claude 3.7 sonnet
