Configure Notifications for Kubernetes

With the PortSIP UCaaS, its support send the alert notifications.

Alert notifications

When an alert changes state, it sends out notifications. Each alert rule can have multiple notifications. In order to add a notification to an alert rule you first need to add and configure a notification channel (can be email, PagerDuty, or other integration).

This is done from the Notification channels page.
