# Nodes

> Reference for all 16 IVR Studio node types - what each does, its settings and its exits.

Source: https://edesy.in/docs/ivr/nodes

An IVR Studio flow is made of nodes joined by connections. Every call enters at Start and follows the connections: speaking text, playing audio, reading keypad input or a spoken answer, calling your API, and finally transferring, recording a voicemail, streaming to an AI bot or hanging up. IVR Studio has 16 node types.

## All nodes

| Node | Palette label | What it does | Exits |
|---|---|---|---|
| [Start](https://edesy.in/docs/ivr/nodes/start) | Start | Entry point of every call | One |
| [Config](https://edesy.in/docs/ivr/nodes/config) | Config | Call-wide voice, language and recording | One |
| [Say](https://edesy.in/docs/ivr/nodes/say) | Say | Text to speech | One |
| [Play Audio](https://edesy.in/docs/ivr/nodes/play) | Play Audio | Plays an uploaded audio file | One |
| [Menu](https://edesy.in/docs/ivr/nodes/menu) | Menu | Keypad (DTMF) menu | One per key, plus timeout |
| [Ask](https://edesy.in/docs/ivr/nodes/ask) | Ask (Voice Answer) | Captures a spoken answer as text | Answered, No answer |
| [Transfer](https://edesy.in/docs/ivr/nodes/transfer) | Transfer | Forwards the call to a phone number | Ends the flow |
| [Dial](https://edesy.in/docs/ivr/nodes/dial) | Dial | Forwards to a number, SIP address or registered user | Ends the flow |
| [Voicemail](https://edesy.in/docs/ivr/nodes/voicemail) | Voicemail | Records a message | Ends the flow |
| [Email](https://edesy.in/docs/ivr/nodes/email) | Email | Emails the workspace owner and continues | One |
| [Pause](https://edesy.in/docs/ivr/nodes/pause) | Pause | Waits a few seconds | One |
| [Hangup](https://edesy.in/docs/ivr/nodes/hangup) | Hangup | Optional goodbye, then ends the call | None |
| [HTTP Request](https://edesy.in/docs/ivr/nodes/http-request) | HTTP Request | Calls your API | One (background) or Success/Failure (wait) |
| [Order Action](https://edesy.in/docs/ivr/nodes/order-action) | Order Action | Confirms, cancels, tags or notes an order on your store | One, or Success/Failure |
| [AI Voice Agent](https://edesy.in/docs/ivr/nodes/stream-to-ai) | AI Voice Agent | Streams the call to your bot over WebSocket | Ends the flow |
| [Reject](https://edesy.in/docs/ivr/nodes/reject) | Reject | Declines the call before it connects | Ends the flow |

## How a call moves through a flow

1. The call enters at **Start**.
2. Each node runs, then the call follows its exit to the next node.
3. Nodes with several exits (Menu, Ask, HTTP Request in wait mode, Order Action with wait on) pick the exit from what happened.
4. A node with no next step ends the call. The builder warns you about these.
5. Transfer, Dial, Voicemail, AI Voice Agent, Reject and Hangup end the flow.

## Where tokens work

Tokens such as `{{caller}}` and `{{var.order_id}}` are filled in at call time. Prompts (Say, Menu, Ask) take `{{var.*}}` tokens; HTTP Request and Email take every token. See [Variables and Tokens](https://edesy.in/docs/ivr/variables-and-tokens).

## FAQ

### Is there a queue node?

No. To reach people, use Transfer or Dial. For agent queues, use the Edesy contact center.

### Can a flow speak more than one language?

Yes. Set a call-wide language in Config and override it on individual Say and Ask nodes. The [Language selection](https://edesy.in/docs/ivr/templates) template shows the pattern.

### Can I record the whole call?

Yes. Tick **Record the whole call** on the [Config](https://edesy.in/docs/ivr/nodes/config) node.

### What happens if the caller presses a wrong key?

They hear "Sorry, that's not a valid option" and the menu repeats.

### How do I send data to my CRM during a call?

Use an [HTTP Request](https://edesy.in/docs/ivr/nodes/http-request) node after a menu branch.

### Can a flow hand over to an AI agent?

Yes, with the [AI Voice Agent](https://edesy.in/docs/ivr/nodes/stream-to-ai) node (WebSocket) or the [Dial](https://edesy.in/docs/ivr/nodes/dial) node to a SIP address.
