openclaw - 💡(How to fix) Fix [voice-call] Preserve full conversation transcript across mid-conversation human holds [1 comments, 1 participants]

Fix Plan

To fix the issue of losing conversation history when resuming from hold, we will implement the following steps:

• Capture the CallRecord.transcript before pausing the conversation
• Format the transcript as a conversation history prefix
• Submit the prefix as a briefing after reconnecting via submitBriefing()

Example Code

// In webhook.ts
const pauseConversation = (callRecord: CallRecord) => {
  // Capture the transcript before pausing
  const transcript = callRecord.transcript;
  // Format the transcript as a conversation history prefix
  const conversationHistory = formatTranscriptAsPrefix(transcript);
  // Store the conversation history for later use
  callRecord.conversationHistory = conversationHistory;
};

const resumeConversation = (callRecord: CallRecord) => {
  // Submit the conversation history as a briefing after reconnecting
  submitBriefing(callRecord.conversationHistory);
};

const formatTranscriptAsPrefix = (transcript: string) => {
  // Format the transcript as a conversation history prefix
  return `You were mid-conversation. Full conversation so far:\n${transcript}\nThey have just put you on hold. Continue naturally when they return.`;
};

Verification

To verify that the fix worked, test the following scenario:

• Start a conversation with the bot
• Put the bot on hold
• Resume the conversation
• Verify that the bot remembers the entire conversation history and responds accordingly

Extra Tips

• Make sure to store the conversation history securely to prevent data loss
• Consider implementing a timeout or expiration for stored conversation histories to prevent storage overload
• Test the fix thoroughly to ensure that it works correctly in all scenarios, including edge cases and error handling.
