Voice Agent version history: compare settings and restore an earlier version
Category: New Release
Location: Voice Agents → Open an existing agent → Version history
Release Date: October 20 2026
Review how your Voice Agent’s settings changed and return to an earlier saved configuration without rebuilding it from memory.
What’s new
• Browse recorded versions with version numbers, change titles, author, and time. The current version is marked Main · Live.
• Compare a selected version with its previous version or the current live settings.
• Use Overview for changes grouped by section, including side-by-side prompt and greeting changes. Use JSON for a settings-level comparison.
• Restore an earlier supported configuration. Each restore creates a new version rather than deleting later history.
What’s included in version history
Version history covers more than prompt edits. It records supported behavior settings across:
• Prompt and greeting
• Voice settings
• Model settings
• Conversation flow
• Data-collection configuration
How it works
• Changes to supported behavior settings are recorded as versions. The first recorded change also retains the preceding settings as a baseline.
• Restoring a version restores those supported behavior settings—not the entire agent.
• Restored settings still pass current validation. If the agent changes while you are reviewing history, refresh and compare again before restoring.
Quick examples
• Compare an edited prompt with its previous version.
• Review changes to voice, model, conversation flow, or data collection alongside prompt changes.
• Restore an earlier supported configuration after an unwanted edit while retaining a record of the restoration.
Getting started
1. Open an existing Voice Agent and click Version history.
2. Select a version and choose Previous or Live for comparison.
3. Review the differences in Overview or JSON.
4. If you have editing permission, select Restore this version, review the proposed changes, and confirm.
5. Reload the agent and check the restored settings before making further edits.
Access and limitations
• Restore follows the same authorization checks as editing the agent.
• Only recorded versions are available; this does not promise a complete history of edits made before recording began.
• Not restored: agent name, description, active/inactive state, assigned phone numbers, knowledge-base documents, tools, or retrieval settings.
• This does not introduce branches, draft publishing, A/B traffic splits, multi-person approval, or per-version call reporting.
Impact
• Understand prompt and other behavior-setting changes without manually reconstructing earlier configurations.
• Recover supported settings while preserving a traceable version history.
