Condition
This topic provides an overview of the Condition component, and describes its configuration as well as supported connections.
Component introduction
Condition component allows routing the message session based on logical expressions. You can use variables, constants, and functions in an expression to evaluate specific conditions. When a condition is met, the session will be routed to the connected component.
Component configuration
After adding Condition component to a message flow, you can configure branches with expressions to route calls based on specific conditions.- Click the branch to configure expression, then click
Confirm.Note:
- Each branch supports only one expression.
-
An expression may include variables, constants, and functions. You can enter
FXto view and select system‑supported functions, and enter$to view and select variables already stored in the current message flow.For more information about functions and variables, see Variables and Functions in Yeastar Expression.

In this example, enter FX_EQUAL($Menu1.receivedMessage,"1") used to check whether the message content that the customer sends in response to the menu with ID Menu 1 is 1. If they match, the session will be routed to the component connected to the branch.
- Optional: To add more conditions, hover over the component and click
to
add more, then repeat Step 1.Note: You can add up to 9 additional branches.
-
Optional: To route the message session or trigger other actions when the component's branch conditions are met, hover over the desired branch and click
to add the next component.For more information about components that support to be connected, see Component connections.
