Prior to IP Office R11.1, call recordings and call details in the recordings database were stored unencrypted. For IP Office R11.1 and higher, they are encrypted. To do that, after the upgrade to R11.1, when Media Manager is restarted it runs an automatic process to encrypted all existing call details in the recordings database.

This encryption process only needs to run once. Once completed it is not run again.

The duration of the encryption process depends on the number of call recordings and the server resources. For example, systems with a million call recordings have been seen to take up to 10 hours.

During the encryption process, call recording of new calls continues as that function is performed separately by the voicemail service.
