Event level is used to indicate how severe or important an event is. Choosing an appropriate level prevents recipients from receiving repetitive information.
Yeastar P-Series Software Edition supports the following event levels:
  • Information: Events that pass general information to recipients.
  • Warning: Events that indicate specific components or applications are not in ideal states, and further action could result in errors.
  • Alert: Events that indicate problems require timely attention.
    Note:
    • When an event occurs, the system gives you a pop-up reminder on the right of PBX web portal.
    • For event whose default level is not Alert, the system will NOT give you a pop-up reminder even if you change the level from Information or Warning to Alert.

Notification contacts and methods

You can set notification contacts to internal users or external users, and notify users in the following ways when events occur:
  • Send Email
  • Call Extension
  • Call Mobile

Notification email templates

Yeastar P-Series Software Edition provides default email template for each event, you can also customize email templates according to your needs.

For more information, see Customize Email Templates.

Auto cleanup of event logs

By default, when event logs reach 50,000, the system automatically deletes the oldest logs. You can change the value, or set the maximum days that logs can be retained.
