Bug

staleCallReaperSeconds is defined in the Zod schema in extensions/voice-call/src/config.ts (line ~297) but is not present in the JSON Schema in openclaw.plugin.json.

Since the JSON Schema has "additionalProperties": false, adding staleCallReaperSeconds to the config causes:

Invalid config at ~/.openclaw/openclaw.json:
- plugins.entries.voice-call.config: invalid config: must NOT have additional properties

This crash-loops the gateway.

webhookSecurity is also missing from the JSON Schema but present in the Zod schema.

Expected

Both schemas should be in sync. Properties in VoiceCallConfigSchema (Zod) should also be in openclaw.plugin.json configSchema.properties.

Versions

• OpenClaw: 2026.3.7
• voice-call plugin: 2026.3.2

Workaround

Don't set staleCallReaperSeconds in config until the JSON Schema is updated. Use maxDurationSeconds (which IS in both schemas) as a partial mitigation.
