The best call instructions read like the notes you'd give a new front-desk hire on their first day. Skip the jargon and write down what you actually want to happen.
Start with the greeting and the three reasons people call most. For each, say what a good outcome looks like: a booked appointment, a message for the right person, or a transfer.
Then set boundaries. List what should always go to a person, like pricing exceptions, complaints, or anyone who sounds upset. Clear boundaries make an AI receptionist trustworthy.
Finally, read your call summaries for the first week. Every question Airhug couldn't answer is a line to add to your knowledge.
