Call Routing Explained: Ring Your Cell First, Then Let Kai Take Over

Call Routing is the setting that decides who answers a call first — your cell phone, Kai directly, a phone menu, or a different rule depending on the time of day. KaiCalls supports five routing modes, and the one most owners start with is Ring-First: your phone rings like normal, and only if you don't pick up does Kai step in and handle the caller.

This is the setting that makes KaiCalls feel like a secretary instead of software. You are not replacing yourself with a robot. You are adding someone who picks up the calls you can't get to — because you're on a ladder, in a meeting, or it's midnight and the phone rang anyway.

This guide covers the five routing modes, what each one actually does, how to set one up, and how routing connects to business hours and phone menus.

What Call Routing actually is

Every phone number on KaiCalls has a routing mode attached to it, configured under Dashboard > Phone System > Phone Numbers. The routing mode is the answer to one question: when a call comes in, who picks it up first?

KaiCalls supports five modes:

• Ring-First — your cell phone (or any number you choose) rings first. If you don't answer within a set number of rings, Kai takes over.
• AI-Only (Direct) — no ringing, no waiting. Kai answers immediately.
• IVR Menu — callers hear a menu ("Press 1 for Sales...") that routes them onward. Covered in full in Phone Menus, IVR Explained.
• Voicemail-Only — calls go straight to voicemail; Kai records the message and sends you a transcript.
• Time-Based Routing — a different mode applies depending on the time of day, so you can, for example, run Ring-First during business hours and AI-Only after hours.

Every mode requires a Fallback Agent — whoever answers when the primary path doesn't. On Ring-First, that's Kai. On the others, it's still Kai, just with a different job.

What Call Routing can do

• Give you first crack at every call, with Ring-First. Your phone rings for a set duration (15–20 seconds is the recommended range) before Kai steps in.
• Detect your voicemail, if voicemail detection is enabled — Kai won't take over a call that your own voicemail already picked up.
• Send Kai straight to the phone with AI-Only, for businesses that want every call answered by AI without a ring-first attempt — useful for high call volume or full after-hours coverage.
• Text you the details after the call. On Ring-First, once Kai handles a call you didn't answer, you get a text with the lead details and a summary.
• Change rules by time of day. With Time-Based Routing you can set business hours (e.g., Mon–Fri 9am–5pm), pick a routing mode for "During Hours" and a different one for "After Hours," and optionally layer in holiday schedules.
• Switch modes anytime without losing your phone number or your agent's configuration.

What Call Routing can't do

• It doesn't decide what Kai says on the call. Routing controls who answers first, not the greeting, the questions asked, or how a lead is qualified — that's the agent's configuration, set up separately.
• It doesn't skip the fallback agent. Every mode requires one; there's no routing mode that leaves a call unhandled if the primary path doesn't pick up.
• It doesn't route on anything other than the ring/answer/time-of-day logic above. Routing by caller identity or by which ad a number came from isn't part of this setting — that's what a dedicated tracking number and Call Tracking are for.
• It isn't a substitute for a menu. If callers need to be split by department or intent before anyone talks to them, that's IVR Menu / Phone Menus, not a Call Routing mode change on its own.

How to set up Call Routing, step by step

1. Go to Dashboard > Phone System > Phone Numbers.
2. Click Configure next to the number you want to set up.
3. Choose a routing mode: Ring-First, AI-Only, IVR Menu, Voicemail-Only, or Time-Based.
4. Fill in the settings for that mode — for Ring-First, that means your ring-first number and a ring duration; for Time-Based, your business hours plus a mode for during and after hours.
5. Select a Fallback Agent — required for every mode, this is who (Kai) answers if the primary path doesn't.
6. Click Save Changes.

For most owners starting out, Ring-First is the easiest first move: enter your cell number, set the ring duration to 15–20 seconds, choose Kai as the fallback, and save. From then on, your phone rings first; if you answer, you talk to the caller directly, and if you don't, Kai picks up and texts you the lead afterward.

How it connects to Business Hours and Phone Menus

Call Routing is the layer that Business Hours and Phone Menus plug into, not a separate system from either one.

Time-Based Routing is where your operating hours become a live rule on the phone line — the "During Hours" and "After Hours" split reads from the schedule you set up under Business Hours, so a change there flows straight into how calls get routed without touching the routing settings again.

IVR Menu is one of the five routing modes itself, not something layered on top of it. When you pick IVR Menu as a number's routing mode, you're handing that call to a menu tree instead of straight to a person or straight to Kai — see Phone Menus, IVR Explained for how the menu options themselves get built.

What it costs

Call Routing is included on every KaiCalls plan — Solo starts at $69/mo, Pro at $199/mo, both with a generous answered-call allowance and no per-minute overage. There's no extra fee to set a routing mode, run Ring-First, or switch between modes as often as you want.

FAQ

What happens to a call I don't answer on Ring-First? Your phone rings for the set duration. If you don't pick up, Kai takes over the call, and afterward you get a text with the lead details and a summary of what happened.

Can I use different routing during the day than at night? Yes. That's Time-Based Routing — set your business hours, pick a mode for "During Hours" and a different one for "After Hours," and optionally add holiday schedules on top.

Does changing my routing mode affect my phone number or my agent's setup? No. You can change routing modes anytime without losing your phone number or your agent's configuration.

Will Kai interrupt a call if my voicemail already picked up? No, if voicemail detection is enabled. Kai checks for that and won't take over a call your own voicemail is already handling.

Which mode should I start with if I'm not sure? Ring-First. It lets you answer when you're available and hands the rest to Kai, which is the setup most owners land on first.
