How you could try it
Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into Voice scheduling agent (Amazon Bedrock AgentCore) or any similar agent and adjust the details to your situation.
Answer inbound calls from patients wanting a home visit. Verify who they are, ask for date and time preferences, book a slot, and read back the confirmation. Hand over to a person if verification fails.
The prompt breaks down into 3 steps you can check as the agent works:
- Answer inbound calls from patients wanting a home visit.
- Verify who they are, ask for date and time preferences, book a slot, and read back the confirmation.
- Hand over to a person if verification fails.
Tip: Have the agent list options with prices and cancellation rules, and only book once you have said yes to one.
