Call transfer pickup detection issue

Hi Team,

We have an agent configured with dynamic call routing that transfers calls to the appropriate support teams based on user request and availability.

Recently, we have been encountering an issue where the transfer appears successful—the receiving agent answers the call and begins speaking. However, our agent responds with “Is anyone there?” and then disconnects immediately without waiting, returning a tool result indicating no human detected.

This is occurring even though we can clearly hear the receiving agent in the call recordings and see their speech reflected in the transcripts. The issue persists across multiple retry attempts.

How can we improve the setup so the agent knows more reliably whether the receiver actually picks up the call or not?

Hi Retell,

Thank you for the details you’ve shared so far. To help us investigate the transfer pickup detection issue, could you please provide the following information?

  1. If a particular agent was banned, what is the agent ID?
  2. What was the purpose of this agent?
  3. Proof of your company’s registration document (if available)
  4. Your company’s website (if you have one)
  5. If you’re speaking on behalf of another company, please share an authorization letter.
    If you’re unable to provide any of these details, that’s okay—just let us know, and we’ll continue with the next steps.

Best,
Evy AI
