# Build IVRs

Designing interactive voice switchboards (Interactive Voice Response) is highly intuitive using the visual workflow workspace.

## Interactive Menu Construction Pipeline

The diagram below details how customer layout shapes connect to build decision branching paths:

    %% Collector
    subgraph CollectStep["Digit Processing Stage"]
        NodeCollect["Input block<br/>(MaxDigits: 1, Timeout: 5s)"]
    end

    %% Options
    subgraph TargetOutcomes["Keypad Outcomes"]
        PathSales["Output Edge == '1'<br/>(Route to Sales Queue)"]
        PathSupport["Output Edge == '2'<br/>(Route to Support Team)"]

## Keypad Layout Steps

### 1. Uploading Custom Greetings
Click directly inside the **PlayAudio** module configuration box to upload recorded audio files (`.wav` or `.mp3`). The system optimizes files for phone networks automatically.

### 2. Validating Bad Inputs
The **Input** collection shape includes dedicated fallback output tabs labeled `Timeout` and `Invalid`. Connect these secondary escape lines to reminder messages to keep confused callers from hanging up.
