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 instead of piecing it together from four separate settings screens.
Call flows are in beta and rolling out team by team. If you do not see the Call flow section on your line, your team is not in the beta yet.

​
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.
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. 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.
Saving takes effect on the next call. Test it by calling the line yourself before you leave for the day.
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 the flow replaces

Once your flow is live, it decides what happens to calls on that line. The four sections that used to do this separately step aside, and each one points back at your flow:
  • Business hours
  • Interactive menu
  • Call routing
  • Missed call handling
They are not lost. If the flow stops governing the line, those settings come back exactly as you left them. Everything else on the line, including members, automatic SMS, notifications and your number settings, works as it always did.
