Hi everyone, please is anyone able to achieve fallback handling with warm transfer experimental? Documentation shows if agent (destination) doesn't pick call, the call should return to the previous assistant to inform the customer that agent is unavailable.. but the call just times out, goes to voicemail and doesn't return to previous assistant. Also, documentation shows settings for transferAssistant, but dashboard UI only has settings for transferPlan. Would appreciate any idea on how to achieve this🙏🏽
