For reliable squad transfers between multilingual agents, use standard (non-GPT real-time) assistants for both the source and destination agents. GPT real-time models currently have limitations with call transfers, especially in multilingual scenarios, so switching to standard models is the recommended solution for consistent transfer functionality. After updating your assistant configurations, test the transfer flow to confirm it works as expected.
