# Conditions

> Call Flow Builder node to add conditions to your call flow.

A Conditions node works like a
[JavaScript if statement](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Control_flow_and_error_handling#if...else_statement).

A condition field can reference variables that have been set in the flow with `%{Key}`,
Request node responses accessed with `%{request_response.<object_field>}`,
or call parameters such as `%{call.from}`.
Add additional conditions to create `else if` conditions.

The `Cond #` path will be executed for a truthy condition. The `Else` path will be executed for a falsy condition.

## Output Node Connectors

**`Condition`** `string`

The condition that is evaluated to determine which path to take. Additional conditions can be added by clicking the `Add condition` button. Additional conditions will act as JavaScript `else-if` statements.

---

**`Else`** `string`

The path to take if none of the conditions are met.

## Node Settings

**`Conditions`** `string`

The conditions that are evaluated to determine which path to take. Additional conditions can be added by clicking the `Add condition` button. Additional conditions will act as JavaScript `else-if` statements.

## Example

### Use conditions to create a block list

In this example, we immediately hang up calls from specific numbers on our block list and forward call from a VIP directly to our administration number.
All other calls will connect to the main reception number.

Flow topology: **Handle Call** → **Answer Call** → **Conditions**. Condition 1 matches a blocked `%{call.from}` number and routes to **Hang Up Call**; Condition 2 matches the VIP number and routes to **Forward to Phone** at `sip:admin@example.com`; **Else** routes to `sip:reception@example.com`.
