Get a Business Phone Number That Answers Itself
New business, or a growing one? Don't hand out your personal cell. Get a local business number in minutes. It rings your cell first. When you can't pick up, Kai answers, takes the message, and texts you the details.
You can't answer from a roof, a crawl space, or the drive between jobs. A caller who gets voicemail calls the next name on the list. With Kai, that caller gets a real answer, and you get the job.
$2 for your first week, then from $10/mo. Cancel anytime.
Or call 1 (417) 835-0402 now and pretend you're a customer. No signup, no form.
Your business number, set up your way
Pick the greeting and voice, forward your line, and call out from the same number.
The Problem
Put your cell on the truck and every call is yours to take, all day and all night. Buy a plain second number and it still won't answer itself. You still have to pick up.
- Google Voice: $10/mo, you answer
- Sonetel: $9.95/mo, you answer
- Quo: $15/mo + per-call AI credits on top
- A missed call goes to whoever picks up next
The Solution
A business number with Kai, your secretary, built in. Here is how a call works.
- Pick a local area code. Your number is ready in minutes.
- A customer calls. Your cell rings first, so you can take it.
- Busy? Kai answers, day or night. He takes the details and can book the visit on your Google Calendar.
- You get a text with who called, what they need, and how to reach them.
Kai's number can be your main line. Already have a number customers know? Keep it and forward only the calls you miss. See the call forwarding guide or how long a port takes.
What answering every call did for one shop: Ken Rent, a tent and party rental business in New Jersey.
When the crew is out setting up tents, the office phone goes to Kai. He takes down the event and sends the team what it needs to quote the job. We matched their orders to the people who called.

Common Questions
How do I get a business phone number?
Sign up at kaicalls.com and pick an area code. Your new number is ready in about 3 minutes. Plans start at $10 per month. That covers the number, Kai (your secretary), and ~20 Kai-answered calls/mo on Kai Backup. Want to hear him first? Call the demo line at 1 (417) 835-0402.
What is the difference between a business phone number and a regular phone number?
A business number is kept apart from your personal cell. You can print it on the truck, put it online, and hand it to a new hire later. Google Voice and Sonetel give you a second number for about $10 per month, but you still have to pick up. Every KaiCalls plan comes with a number that rings your cell first. When you miss it, Kai picks up, asks the right questions, books the visit, and texts you the details.
Can I keep my existing business phone number?
Yes. You have two choices. You can move (port) your number to KaiCalls. Most ports take one to three weeks. Or keep your number where it is and forward only the calls you miss to Kai. Do not forward all calls, or your own phone stops ringing. Our call forwarding guide shows the steps for your carrier.
How much does a business phone number with AI answering cost?
KaiCalls plans start at $10/mo with unlimited secretaries. Monthly plans and call allowances: Kai Backup $10 (~20 Kai-answered calls/mo), Kai Line $79 (~170 Kai-answered calls/mo), Kai Office $349 (~800 Kai-answered calls/mo). There are no per-minute overage charges. Your plan includes an expected monthly call allowance. If your call volume stays higher, we recommend the next plan and notify you before anything changes. You can choose to keep your current plan, and we move you back down if volume drops. Software features are available on every plan. Texting registration coverage and meeting minutes differ by plan. Extra phone lines, additional meeting hours and optional website call tracking cost extra. Connected services require setup and messaging needs sender approval. No setup fees, no per-seat charges.
Is a business phone number that answers itself better than Google Voice?
It depends on what you need. Google Voice Starter is $10 per user per month (as of September 2026) for a second number you answer yourself. Kai Backup is $10 per month and includes a phone number plus ~20 Kai-answered calls/mo, so Kai picks up when you miss calls while working — on a job site, in a meeting, driving, or after hours.
