Starting February 5, 2021 you will be able to view call logs in Console--and retrieve the resources via GET to the /Calls endpoint--for thirteen months after the resource is created. This represents a significant change as these logs are currently stored indefinitely by Twilio and retrievable via Console and API.
Twilio provides a Bulk Export utility in Console. Bulk Export will generate S3 files containing one day of data per file and deliver the download link via webhook, email, or Console. Records older than thirteen months will only be able to be retrieved via Bulk Export.
If you view logs in Console there is no follow up action, but just be aware that calls and conferences will now only display logs for the previous 13 months.
If you perform log extraction via API on a rolling basis, it is important to verify that you are pulling the logs at a frequency that will remain unaffected by this change.
