Voice interviews last up to 60 minutes. Reconnecting uses the same session and does not cost another credit. If our voice provider fails to start a session, we restore the reserved allowance automatically. Paid connection failures reported in the first minute qualify for one automatic credit restoration per day; a replacement voice session is available after the original 60-minute window expires. Contact support if you need help with another failed session.
