Cloud Voice stores your operational data: call detail records (CDRs, the per-call records used for reporting and billing), call reports, voicemails, recordings, chat data, faxes, backups, and the various system logs, all in a default storage area. To keep that storage from filling up, the Auto Cleanup feature enforces a limit on each data type and removes the oldest entries automatically once a limit is reached. This page describes every auto cleanup setting and its default and maximum values.
Each data type has its own limit, defined either as a maximum count (or storage size) or as a number of days to retain records. When a limit is reached, Cloud Voice deletes the oldest records of that type to stay within it. A retention setting of 0 days means the records are never removed on a time basis.
For many data types, reaching 90% of a limit also raises an Auto Cleanup Reminder event, which notifies the contacts you have configured so you can act before anything is deleted. This reminder applies to CDR, call reports, voicemail, recordings, recording logs, external chat data, and system backup files. It does not apply to fax data or to the event, email, operation, and system log categories, those simply drop their oldest records when the limit is hit.
The largest number of CDRs to keep. When the limit is reached, the oldest CDR is deleted. Default: 200,000. Maximum: 300,000 with the call timeline enabled, or 700,000 with it disabled.
CDR Preservation Days
The longest a CDR is kept. When a CDR reaches this age, it is deleted. Default: 0 (no limit).
The longest a recording file is kept. The oldest recording files are deleted when they reach this age or when your recording capacity (in recording minutes) is reached. Default: 0 (no limit).
The largest number of recording logs to keep. When the limit is reached, the oldest recording logs are deleted. Default: 1,000,000. Maximum: 3,000,000.
Recording Logs Preservation Days
The longest a recording log is kept. When a log reaches this age, it is deleted. Default: 0 (no limit).
The total storage allowed for external chat files, including documents and images. When the limit is reached, the oldest chat files are deleted. Default: 1.
External Chat Files Preservation Days
The longest an external chat file (document or image) is kept. When a file reaches this age, it is deleted. Default: 7. Enter 0 for no limit.
The total storage allowed for fax files. When the limit is reached, the oldest fax files are deleted. Default: 1024.
Fax Log Preservation Days
The longest a fax log is kept. When a log reaches this age, it and its associated fax files are deleted. Default: 7. Setting this to 0 removes the day limit; even so, to protect performance the oldest fax logs and their files are deleted once the total reaches 200,000.
The largest number of event logs to keep. When the limit is reached, the oldest event logs are deleted. Some event logs cannot be cleaned up automatically; once those reach 5,000, the oldest among them are deleted. Default: 50,000. Maximum: 1,000,000.
Logs Preservation Days
The longest an event log is kept. When a log reaches this age, it is deleted. Default: 0 (no limit).
