Export calls to a CSV file. The CSV file will be available for download for 24 hours.
The export will be performed asynchronously. The task status can be checked with
the Tasks endpoints: when the task is done, its result contains the url of
the CSV file.

The CSV file is UTF-8 (with a BOM). Its columns are the fields of the call webhooks
(direction, callid, callerNumber, callee, started, durationBilled,
billingDebit...). The separator is ; for the accounts in French, , otherwise.
You can export calls up to 24 months back.

You cannot export more than 31 days of calls at once. If you need to export more
than 31 days, you will need to split the export in multiple requests.

Exporting calls is a heavy operation. It can take a long time to complete, depending
on the amount of calls to export. That is why you are limited to a maximum of 5
exports per day.

If you need to process calls in real-time, you should use webhooks, or the fetch
action with Callr Actions.
