Get a Business Phone Number That Answers Itself
KaiCalls is a business phone number with a built-in AI receptionist for $69 per month flat. You get the number, the 24/7 answering, the appointment booking, and the CRM push in one plan. No per-seat pricing, no per-call credits, no setup fees.
Most business phone services give you a number. Google Voice, Sonetel, and Quo (formerly OpenPhone) all make you answer the call yourself — or pay extra for AI credits. See Quo's published rates at openphone.com/pricing.

How do I get a business phone number?
You sign up at kaicalls.com, choose an area code, and a business phone number is provisioned to you in about 3 minutes. KaiCalls plans start at $69 per month and include the number, the AI receptionist, and 150 included minutes of answering per month. You can also test the product first by calling the demo line at 1 (472) 238-3790.
What is the difference between a business phone number and a regular phone number?
A business phone number is separate from your personal cell so you can publish it, forward it, and hand it off. Services like Google Voice and Sonetel give you a second number for under $10 per month but you still have to pick up. KaiCalls gives you a business phone number that answers itself — Kai picks up, qualifies the caller, books the appointment, and texts you the details.
Can I keep my existing business phone number?
Yes. You can port your existing business phone number into KaiCalls, or you can use call forwarding so your current number rings your cell first, then rolls over to Kai if you miss it. Setup takes about 90 seconds for forwarding or a few days for a port.
How much does a business phone number with AI answering cost?
KaiCalls starts at $69 per month flat for the number plus 150 minutes of AI answering. Growth is $149 per month for 400 minutes. Professional is $299 for 900 minutes. Business is $499 for 1,800 minutes. Enterprise is $999 for 4,500 minutes. Overage is $0.10 to $0.15 per minute. 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 is cheaper at $10 per month if you just want a second number and you are available to answer. KaiCalls is worth the $69 per month if you miss calls while working — on a job site, in a meeting, driving, or after hours. For contractors, a single missed job (say, a $2,500 EV charger install) pays for three years of KaiCalls.
