112:Avaya IP Office User programming may appear not to save
*Release Date: 4 November 2005
It has been reported to Avaya that on occasion user programming changes may appear not to save. This is due to the way that IP Office saves configuration changes.
IP Office has two types of memory:
• Flash memory • RAM memory
RAM memory is the IP Office’s working memory. Flash memory is the IP Office’s database. The contents of the RAM memory are written to Flash memory every night at midnight.
The Flash memory is backed up by an on-board battery and is therefore maintained over a power down. The RAM memory is not.
If a user changes their Voicemail password (for example) via the telephone Interface or with a merge sent from the Manager, then the config is saved to the RAM memory. When the Manager application sends a config utilising an immediate reboot request then
the config is written directly to the Flash memory and then copied to the RAM (working) memory when the unit reboots.
Care must be taken when making changes via the manager application, as changes made by users during the time that the config is being worked on offline will be lost when the downloaded config is sent back to the IP Office.
If power to the IP Office is reset before the RAM memory has been written to the Flash (Midnight), then the RAM memory is overwritten by Flash which holds the last immediate backup file or Midnight’s backup file as the unit powers up. Thus user changes made
prior to a reset may be removed or replaced with the reset of the IP Office system.
