When Mia answers

Pick one of three modes for each line, or turn her off. Switch from the app, a home screen widget or Siri, for example as you walk into a job.

Always

Mia answers every call on the line. Good for busy seasons, or when you’re on a job all day.

Only after hours

You take calls during your business hours, and Mia answers outside them. Hours are Monday to Friday, 9 to 5, until you set your own.

Only when you don’t pick up

Your phone rings first. If you don’t answer, Mia does. A good place to start, because you still take the calls you can.

Teach Mia

What to teach her

Type your business name or website and Mia drafts the first version for you. Then check each part. The more specific you are, the better she answers.

What to teach Mia
Business name and greetingThe first thing callers hear, for example “Thanks for calling Hollis Heating, this is Mia.” Keep it short.
ServicesWhat you do and what you don’t, so she can tell a caller straight away if you’re the right fit.
PricesReal prices or ranges, like “service call $89” or “drain clearing from $150”. She only quotes prices you gave her.
HoursYour business hours. She offers booking times inside them, and appointments are 1 hour unless you change the length.
Where you workThe towns or neighborhoods you cover. For on-site work she asks for the job address.
Urgent wordsWords that mean “put them through to me”, like “no heat”, “flooding” or “locked out”.
What not to promiseAnything she should never offer, like same-day visits or discounts. She sticks to it.

Voices and testing

Pick her voice, then hear her

Warm

The default. Friendly and easy to listen to, a good fit for most businesses.

Bright

A brighter, more upbeat sound, for salons, studios and anyone who wants a lively front desk.

Calm

A calmer, steady sound, for callers who may be stressed, like a burst pipe or a lockout.

Whatever voice you pick, her name stays Mia. Tap “Hear Mia answer a call” in the app for a test call with her. It uses no credits, so make one after every change to her answers.

Example only

A sample call and the slip you get

A made-up call to a fictional heating company. The names, address and number are invented. Mia quotes the service-call price because the owner gave it to her.

Transcript

Mia: Thanks for calling Hollis Heating and Air, this is Mia. How can I help? Caller: Hi, my furnace is making a rattling noise when it starts up. It still works, but it’s loud. Mia: Sorry to hear that. It sounds like a service visit. A service call is $89, and the tech will tell you the repair price before starting. Would you like to book one? Caller: Yes please. Anytime Thursday works. Mia: I have Thursday at 10 AM or 2 PM. Which is better, and what’s the address? Caller: 2 PM. It’s 88 Birch Lane. Mia: You’re booked for Thursday at 2 PM at 88 Birch Lane. You’ll get a text with the details. Anything else? Caller: No, that’s it. Thanks!

What callers get, and what you get

The caller gets

  • One “what happens next” text from your number, once per call, like when you’ll call back.
  • If they booked, a confirmation text with the time and place.
  • A reminder before the visit. They reply C to confirm or R to reschedule, and you see the answer on the booking.
  • After you mark the job done, a review request if you want one.

You get

  • A slip on Today: who called, what they need and ticks for New lead, Wants a call back and Urgent.
  • An AI summary of the call, 1 credit per call. On by default; turn it off in Settings.
  • The full transcript under the slip, so you can check exactly what was said.
  • Buttons to call back or text from the same number.

Hand to me, urgent words and quotes

  • Hand to meWhile Mia is on a call, tap Hand to me in the app, or on the iPhone Live Activity, and the caller comes to you. Mia’s rate (48 credits a minute) stops, and the rest of the call is billed at the normal call rate.
  • Urgent words you chooseAdd the words that can’t wait, like “gas smell”, “no heat” or “locked out”. When a caller says one, Mia tells them she’s connecting them and passes the call to you.
  • Quotes from her pricesSend a quote built from the price list you gave Mia. The customer gets an itemized total by text. If they reply YES within 7 days, it’s marked accepted and the lead moves to Quoted.
  • Bookings inside your hoursMia only offers times inside your business hours, in your business’s time zone. Travelling doesn’t move your hours; only you change the time zone.

Honest limits

What Mia doesn’t do

  • No emergency calls. 2Line.AI doesn’t support 911, and Mia can’t call emergency services. She flags urgent calls for you.
  • US numbers only. Mia answers on local US 2Line.AI numbers. No toll-free, no international and no number porting.
  • No CRM, Google Calendar or Zapier connections. Bookings sync to your iPhone Calendar, and leads and slips live in the app.
  • No human receptionists. Mia is an AI. When a call needs a person, she hands it to you.
  • She only knows what you taught her. Keep your services, prices and hours up to date, and make a test call after big changes.
  • She needs credits. At zero credits, Mia pauses with calls and texts, and callers hear busy until you add a pack.
