Partner wants a read/write API endpoint for the Voice AI attendant greeting field to enable real-time outage messaging. Their workflow: a Cloudflare worker reads from a global status board, a Claude task is triggered when a major outage occurs, and an MCP updates the greeting with contextual outage information. Once the outage clears, the greeting is automatically reset to its normal state. This requires at minimum a writable API endpoint for the greeting field on the Voice AI attendant configuration.
