Agent-Specific Troubleshooting

1

Verify transfer_call function

Confirm you’ve added the transfer_call function to your agent’s function list. See the Function Calling Guide.
2

Review transfer conditions

Update your prompt to clearly define when a transfer should occur. Ensure the transfer_call function description is specific and unambiguous. Test with sample scenarios to validate triggers.See Call Transfer Setup.

​
General Notes

Call transfer is only supported for phone calls — not web calls.

​
If Transfer Triggers but Fails

Telephony issues — Transfer failures are similar to outbound call failures. Check the SIP connection log in the call logs and refer to Debug Outbound Call. Could not detect human — If human detection is enabled, the transfer may fail if:
  • No human was present (e.g. IVR or voicemail answered)
  • The other party spoke after the detection timeout expired
  • Speech was too similar to an IVR and wasn’t recognized as human
