Note: There is a system-wide limit for voicemail storage on the CompactFlash (CF) card. The limit is calculated by measuring the current free space of the CF card, subtracting 100MB required for working space by system upgrade, logs and backups, and calculating a percentage of the free voicemail capacity compared to the total size for all voicemail currently stored. When this voicemail storage reaches 100%, no new voicemails are recorded until users delete some messages from their mailboxes.
