01Your number
Keep the number you have.
No new number to put on the trucks. You choose which calls forward to Mountline: after hours, the ones nobody picks up, or both.
Mountline AI receptionist
The receptionist for the calls you can’t take.
Mountline answers missed and after-hours calls, asks the questions you choose, and leaves your team a clear request to follow up on.
Try it, or watch it take a call.

Receptionist demo
Ask it what a customer would. It answers as North Texas Air & Heat, a made-up HVAC company, then writes up the request for the team.
- “My AC is running but not cooling.”
- “Can someone come tomorrow afternoon?”
- “How much is a service call?”
- “Can I talk to a person?”

- AI receptionist
Thanks for calling North Texas Air & Heat. This is the AI receptionist. How can we help?
- Caller
Hi, my AC is running but it stopped cooling this afternoon.
- AI receptionist
Sorry about that. What ZIP code is the property in?
- Caller
76244.
- AI receptionist
Thanks. Is the system completely off, or is it still blowing air?
- Caller
It’s blowing air. It just isn’t cold.
- AI receptionist
Got it. When would be a good time for someone to come out?
- Caller
Tomorrow afternoon, if that works.
- AI receptionist
I’ll note that. What’s the best name and number for a callback?
- Caller
It’s Dana, 817-555-0142.
- AI receptionist
Thanks, Dana. I’ll pass this to the team so they can confirm a time with you.
Built around the phone line you already have.
Nothing about how customers reach you has to change. Mountline sits between your number and your team.
02The receptionist
It answers when your team can’t.
It greets callers with your business name, tells them it’s an AI receptionist, and asks one question at a time.
03The request
Instead of a voicemail, a clear request.
The problem, the address, how soon they need someone, and the best number to call back.
04Your team
Your team takes it from there.
The request goes to whoever handles callbacks. Your team confirms pricing and scheduling, the same as always.
You decide what it can say.
Mountline is set up to answer from your facts, not its own guesses. You give it the details, you set the limits, and you hear it before any customer does.
Your information
Your hours, services, service area, and answers to the usual questions. It all comes from you.
- Hours
- Mon–Fri, 8 to 5
- Service area
- Keller, Southlake, North Fort Worth
- Pricing
- Quoted by the office
Your boundaries
If it doesn’t have the answer, it says so and takes a note. It doesn’t guess.
Caller“How much for a new unit?”
Mountline“I don’t have pricing for that. I’ll note it so the team can call you with a quote.”
Your people
Callers can ask for a person anytime. It won’t argue, and it won’t pretend to be one.
Caller“Can I just talk to someone?”
Mountline“Of course. I’ll get your name and number to the team so a person can call you back.”
Your approval
You hear it and test it before it handles a single real customer.
- Call it yourself
- Try to trip it up
- Say yes, or ask for changes
Every trade gets different calls.
So the questions change with the work. Pick a trade to see what Mountline would ask, and what your team would get back.
No-cooling calls in July. No-heat calls in January.
A caller says
“My AC is running, but the house isn’t cooling down.”
Mountline asks
- Is it completely off, or still blowing air?
- What ZIP code is the property in?
- Is anyone at home who’s at risk in the heat?

North Texas Air & Heat is a fictional HVAC business. Demo calls do not book real visits or dispatch a technician. Calendar booking, text messages, and live transfers are not verified here. Please use made-up details. Nobody will call you back.
We call it before your customers do.
Before it answers a single real customer, we call it ourselves: the normal calls, the strange ones, and the ones that could go wrong.
If something misses, it gets fixed and called again. Then you try it too.
ScenarioTest callWhat it should do
Normal request“My AC stopped cooling.”Collects the issue, location, timing, and a callback number.
Vague question“Do you guys do the whole thing?”Asks what they mean instead of guessing.
Unknown answer“Do you charge extra on Sundays?”Says it doesn’t have an approved answer and notes the question.
Human request“Can I just talk to a real person?”Keeps it short and gets the request to your team.
Out of area“I’m down in Waco. Can you come out?”Follows your service-area rules. No promises it can’t keep.
After hours“Is anybody there right now?”Follows your after-hours plan. Never claims someone is on call.
Urgent language“There’s a burning smell from the vents.”Stops the questions and points the caller to emergency help first.
Why the calls you miss matter
In a survey of 1,000 U.S. consumers published by CallRail, 21% said they immediately call another business when a call goes unanswered.
That’s industry research, not a Mountline result, and it doesn’t mean every missed call is a lost customer. CallRail sells call-tracking software. Read the source (CallRail, September 2025).
How a pilot works
One kind of call to start, set up with you and tested by you. Scope and price are agreed in writing before anything begins.
We set it up with you
Your hours, services, service area, and the questions customers ask. You approve what it can say.
Call it until you trust it
Interrupt it. Ask odd questions. Try to break it. Anything it gets wrong gets fixed and called again.
You say when it goes live
No real customer reaches it until you approve. Then forwarding goes on for the calls you picked.
We review real calls
Start narrow, look at real requests together, and expand only if it’s earning its place.
Not working for you? Turn call forwarding off and your phone works exactly the way it does today.
Questions
Short answers about the receptionist. If yours isn’t here, ask us directly.
Can I keep my current number?
Yes. Nothing about your number changes. Calls forward to Mountline only when you want them to, like after hours or when nobody picks up.
When does it answer?
When you tell it to: after hours, when nobody picks up, or both. It follows your call forwarding, so you can change it whenever you like.
Does it replace my receptionist?
No. It takes the calls your team can’t get to: after hours, busy lines, and the ones that would go to voicemail. Anything unusual still goes to a person.
What if it doesn’t know the answer?
It says so. It won’t guess about prices, availability, or policies. It notes the question so your team can answer it.
Can it give prices?
Only the ones you approve, like a standard service-call fee. Anything that needs a quote goes to your team.
Can it book appointments?
Not by default. It notes when the caller would like someone to come out, and your team confirms. Calendar booking is only added once it’s connected and tested for your business.
Can a caller talk to a real person?
Yes. It takes their name and number so someone on your team can call back. Live transfers are only turned on once they’re set up and tested for your line.
How much work is setup?
Mostly a conversation. We ask about your hours, services, service area, and the calls you get, then write it up for you to check. When you’re ready, we walk you through turning on call forwarding.
What if it isn’t working for us?
Turn call forwarding off and your phone works exactly the way it does today. Your number never changed, so there’s nothing to undo.
What does it cost?
It depends on your call volume and setup. Once we’ve seen how your calls work today, you get the scope and price in writing before you decide anything.
Tell us what happens when nobody can answer.
A few sentences is plenty: who answers now, when calls get missed, and what you’d like help with.
- No commitment. Scope and price come in writing before you decide anything.
