JustCall vs KaiCalls
A phone system priced per user, or one flat price.
JustCall is a cloud phone system for sales and support teams, priced per user. KaiCalls is one flat monthly price for the business: your cell rings first, and Kai, your secretary, answers the calls you miss. Here is how to tell which one fits.
Per user/month billed annually, $39 billed monthly, 2-user minimum. As listed on justcall.io on 17 Oct 2026.
~20 Kai-answered calls/mo. One price for the business, not per user.
No per-minute charges on any plan. Cancel anytime.
Two good products for different businesses.
JustCall equips a team that works the phones. KaiCalls is for the owner who answers most calls and needs backup for the rest. The question is which shape matches your day.

Where KaiCalls is the right shape

Four situations, four honest answers.
Two of these point at JustCall. That is the category line doing its job.
You run a sales floor or support desk with people on the phones all day
JustCall.
That is what JustCall is built for. Each seat gets a dialer, a shared inbox, routing and reporting, and the coaching tools help your team get better. Per-user pricing is fair when every seat is a person on the phone.
You are one person, or a small crew, and calls come in while you work
KaiCalls.
You do not need seats. You need someone to pick up when you cannot. Your cell rings first, and when you miss it, Kai answers, takes the details and texts you who called and what they need.
A per-user bill with a 2-user minimum does not fit your business
KaiCalls.
KaiCalls is one flat monthly price for the business. Kai Backup is $10/mo for ~20 Kai-answered calls/mo, with no per-user charge and no per-minute overage.

When you miss a call, Kai, your secretary, answers it, takes the details and texts you who called and what they need.
How much does JustCall cost?

Do I have to give up my number or forward my calls?
No. You keep your number. Forwarding is optional. You can use your KaiCalls number as your main line. If customers already call an old number, forward only the calls you do not pick up. Forward-all would send Kai every call and your own phone would stop ringing.
When is JustCall the better pick?
When you run a team that works the phones all day: a sales floor, a support desk or a call center. JustCall gives each seat a dialer, shared inbox, call routing, CRM integrations and coaching tools. Per-user pricing fits that, because every seat is a person on the phone.
Still shopping around?
Same honest treatment for the other phone options on your list.
KaiCalls vs Dialpad
Another per-seat team phone platform, same honest comparison.
KaiCalls vs Grasshopper
A virtual phone system against a line with a secretary built in.
KaiCalls vs Quo
Two takes on the small business phone line.
KaiCalls vs Google Voice
A basic business number against one that answers when you cannot.
A team on the phones? JustCall. Just you, and the calls you miss? KaiCalls.
That is the whole choice. Everything else on this page is detail.
Per-user pricing pays off when people sit in the seats. If you are the whole team, and you are on a job when the phone rings, a seat does not answer the call.
With KaiCalls your cell rings first, Kai answers the calls you miss, and you get a text with who called and what they need. One flat monthly price, and you keep your number.
Warm transfers without the dashboard mess
KaiCalls is built for teams that still want a human in the loop when the call matters. The AI captures context first, then routes the caller with a concise briefing instead of forcing staff to open a console mid-conversation.
Ring the team first
KaiCalls can ring your team before the AI takes over, so live staff still get first chance at urgent calls.
Brief before handoff
The transfer includes who is calling, what they need, and why the call should move to a human now.
Capture the full trail
Each call can produce a transcript, structured lead fields, score, owner alert, and CRM or webhook handoff.
