How long are recordings retained and available through the API?

We have been calling with Ring Central for over two years. We record every call. We can see the recordings in the call log on the Ring Central Admin portal but are unable to retrieve recordings older than 30 days via the API. Using the call-log method below will return records but not a media URL. Without this, we cannot download the recording. We would like to retrieve the recordings for the last 90 days. Is this possible using the API?
