Keywords:
The IP Office system can be configured to generate alarms. These alarms can be sent from the IP Office using SNMP, SMTP e-mail or Syslog alarm formats. The voicemail server preferences set the levels at which the server indicates to the IP Office to send an alarm.
For Voicemail Pro Server Edition, the IP Office system also sends SNMP alarms based on the percentage of the available free space of the total disk space. Those SNMP alarms are:
  • Disk State Critical - Free disk space is less than 5%
  • Disk State OK - Free disk space is between 5 to 10%
  • Disk State Free - Free disk space is greater than 10%
  • Disk State Stop Recording - Free disk space is 0.
These settings can only be adjusted in the preferences of the central/primary voicemail server. The settings of other voicemail servers in the network automatically match those settings.

Description
Alarm Threshold Unit
Under Alarm Threshold Unit, select either Disk Space left (MB) or Recording Time left (min).
Alarm Threshold Level
Enter the number of units (minutes or MB) at which SNMP alarms are to be triggered. The minimum value that you can enter is 11. In addition to this alarm, the following additional alarms are also set based on the Alarm Threshold Level:
  • Space OK Alarm: This alarm is triggered when the amount of available space returns to above a level set at Alarm Threshold Level plus 30.
  • Critical Alarm: This alarm is set at 30. If the Alarm Threshold Level is set at less than 40, the critical alarm is set at Alarm Threshold Level minus 10.
    • Note that the critical alarm value decreases if you decrease the Alarm Threshold Level, but the critical alarm value does not increase if you increase the Alarm Threshold Level. So, the critical alarm value keeps on decreasing and remains set at the least value that it takes. To reset the critical alarm back to 30, click Default Settings.
Default Settings
To return to the default alarm settings, click Default Settings. The Alarm Threshold Level is reset to 60. The Space OK level is reset to 90. The Critical Alarm level is reset to 30.
