A call flow is the path a caller takes through your line: a menu, an announcement, ringing your team, voicemail. You build it on a canvas, one step at a time, and you can see the whole journey at a glance.
Where to find it
1
Open your line settings
Go to web.withallo.com, then Settings and Numbers, and pick the line you want to work on.Or open the call flow in Allo directly, then select Open designer.
2
Find the Call flow section
Scroll to Call flow. It carries a Beta badge. If the line already has a flow, a small read-only map of it appears under the heading.
3
Open the designer
Select Open designer. The flow opens full screen, with your steps on the canvas and a settings panel on the right.
How a flow is built
Every flow starts with Incoming call. That step cannot be removed, and everything else hangs off it. From there you add steps. Each step does one thing, and some of them split the call into branches: a phone menu branches per key, business hours branches into Open and Closed, and so on. You configure the selected step in the panel on the right.The steps you can add
Steps are grouped in the picker under Calling, Conditions and AI.
Phone menu and Ring this line carry the most settings, so each has a page of its own: build a phone menu and ring your team.
Some steps must always say what happens next, so Allo creates that branch for you and will not let you leave it empty:
- A Phone menu always has a No selection branch, for callers who press nothing or press the wrong key.
- Ring this line always has an If missed branch, for when nobody picks up.
- Business hours always has Open and Closed.
- Contact property always has Match and No match.
Saving and going live
Select Save in the top right. There is no separate publish button: saving is what puts the flow in front of callers. While you have unsaved work, the header shows Unsaved. Discard throws your unsaved edits away and puts the last saved version back. If a step is still missing something, Save is blocked and the step that needs attention is highlighted with what to fix, for example “Choose what this step does” or “Add at least one member to ring”.What lives in the flow
The call flow is the only place to set what happens to incoming calls on a line. Business hours, the phone menu, who rings and what happens after a missed call are all steps in the flow. There are no separate settings sections for them. The automatic text after a missed call is set in the flow too, with a Send SMS step. Everything else on the line, including members, waiting music, notifications and your number settings, stays in the line settings.Limits
