First call

Create a workflow

From an empty workspace, create a workflow. Blank Canvas starts from nothing, From Template starts from a written prompt for a common job, and Create with AI opens the same blank workflow with the AI builder alongside it.

Whichever you pick, the workflow arrives with one node and no edges.

• Start Call is that node, and it is the single entry point. Every workflow has exactly one, it cannot be deleted, and you cannot add a second.
• Nodes are the steps you add around it — a thing to say, a question to ask, a system to call.
• Edges are the lines you draw between nodes. Each one is the rule that decides when the conversation moves on.

Add an End Call node from the node panel and drag an edge from Start Call to it. That is the shape of every workflow you will ever build: an entry point, some steps, an ending.

Name the workflow something you will recognise in a list of thirty. "Test 2" is a decision you regret in a fortnight.

Write the prompt

Open the Start Call node. Two fields matter on the first pass.

• Greeting — the literal first thing the caller hears. It is deliberately separate from the prompt, because the opening line is the one moment you want exact words rather than a model's interpretation of them.
• Prompt — everything else: what the agent is trying to accomplish at this step, and how it should behave while doing it. There is no separate personality setting anywhere in the product. Tone lives in the prompt, and so does judgment.

Keep the first prompt small. One clear objective, tested, then add the next as its own Agent Node.

Test it in the browser

Save the workflow, then choose Test → Web Call. Woise creates a run and opens the run screen — a full page of its own, not a panel on the canvas. Microphone controls and the Start Call button sit on the left; the live transcript builds on the right as you speak.

This is not a simulation. It runs the same pipeline a phone call runs — the same speech recognition, the same model turn, the same speech synthesis, the same turn-taking — with the phone network swapped for your microphone and speakers.

Three things worth knowing about the Test menu:

• It stays disabled while you have unsaved changes or validation errors. Save first.
• Web Call runs your draft, so you are hearing the edit you just made rather than the published version.
• Phone Call places an outbound call to a number you type, and Text chat runs the same graph as typed messages.

Iterate here. Change a line of the prompt, save, call again, listen.

Attach a phone number

Once it sounds right in the browser, connect it to a real number. This step differs by region, because number sourcing is a compliance question before it is a technical one.

Full detail on both paths lives in Numbers.

Place a real call and read the transcript

With a number attached, call it — or, for an outbound agent, have it call you.

Every call is a workflow run, and the distinction matters more than it sounds. The workflow is the definition; the run is one execution of it. Editing the workflow afterwards does not rewrite the runs that came before, which is what makes a transcript worth trusting as a record.

Each run carries four things:

The recording and transcript appear alongside the workflow's other runs once the call completes — Recordings covers where to find them and what they hold.
