# The call's window is closed

> 409 outside_call_window

The call named the hours it may start in, and this is not one of them.

## What to do

`detail` says when the window opens next. Schedule the call for then — `POST /v1/scheduled-calls` with the same window places it at the first moment it is open — or send it again once it is.

## Retrying

Yes, once the window is open.
