The amount of space you need will depend on how much recording you plan to do and how often you plan to retrieve them from the FTP site.
Conversion rates for Recording:
- 16 K/B = 1 second of recording
- 250 MB (default amount) = 4 hours of recordings
- 1 GB = 16 hours of recordings
Recordings are deleted every night at Midnight PST. No recordings are deleted for the prior day. For each earlier day, if the total amount of recordings exceeds the purchased recording space, that day and all prior days are deleted - no partial days of recordings are retained.
