# Mystery-shop your own phone line: have an AI agent call your business at lunchtime and after hours like a customer would, then score what callers actually hear

Most owners never hear what a customer gets when they ring at lunchtime, after hours or on a busy Saturday: unanswered calls, a full voicemail box, an outdated greeting or a rushed answer. On Oct 26, 2026 a builder posted on X that, now that his Grok Bot can make phone calls, he built a bot that finds out what small business customers hear when they call at lunchtime. The prompt below sets up the same check on your own business with any AI agent that can place calls, or as a script for a friend to follow, and turns the results into a short fix list.

## Inputs to collect first
Ask the user for anything below that they haven't already given you. Don't guess missing facts.

- Name, type, number to call, opening hours
- E.g. answered within 4 rings, greeting with business name, hours…
- Service

## Instructions

Do the task below with the user's inputs in place of each [bracket].

Help me mystery-shop my own business's phone line. Business: [name, type, number to call, opening hours]. What a good call should include: [e.g. answered within 4 rings, greeting with business name, hours, price range for our main service, how to book]. 1) Plan 5 test calls at different times: lunchtime, just before closing, after hours, a busy weekend slot and a quiet mid-morning. 2) For each, write a short realistic caller script with one common question (e.g. 'Do you have anything available this week?', 'How much is [service]?'). The caller must say it's an AI calling on behalf of the business owner if asked, and must not book, pay for or agree to anything. 3) After each call, record: time, rings before answer, answered by a person / voicemail / no answer, greeting used, whether the question was answered, hold time, tone, and whether a voicemail was returned and how fast. 4) Summarise across all calls: the 3 biggest problems, what each is likely costing in missed customers, and a simple fix for each (e.g. new voicemail greeting text, call forwarding at lunch, an answering service or AI receptionist, a FAQ sheet by the phone). Only call my own business's number.

## Safety checks (share these with the user)

- Check every figure, price and total against your own records before anything is sent, posted or booked. A person approves refunds, discounts, payments and price changes.
- Remove names, contact details, account numbers and other personal data the task doesn't need before you paste, and check your AI tool's data and training settings.
- Check names, dates, numbers and any claim against your own source material before you use the answer. AI can misread or invent details.
- Say clearly which parts need a person to review or approve before anything is sent, paid, posted or filed.
