Call flows that call other call flows

Call flows can now reference other call flows as subflows — like a function call. Build a "main reception greeting" once and reuse it across every DID without copying the nodes.

What this lets you do

• Author a flow once (e.g. "After-Hours" with the right voicemail box, holiday check, and emergency number).
• In any other flow, drop a Flow Reference node and pick the saved flow.
• Edit the original; every flow that references it picks up the change automatically.

Setup

1. Build the flow you want to reuse. Save it normally.
2. In any other flow, drag the Flow Reference node onto the canvas.
3. Pick the target flow from the dropdown.
4. Wire it like any other node.

Worth knowing

This is the dialplan equivalent of a function call — there's no copy made under the hood. Change the source flow, and every reference updates on the next dialplan reload. Great for company-wide updates ("we're moving the after-hours number from voicemail to a cell phone") that would otherwise mean editing every flow by hand.
