We are currently implementing on-call alerts using on-call scheduling in ServiceNow, and we plan to use the Notification Devices (cmn_notif_device) table to store information related to groups, or direct phone numbers.
We are seeking detailed documentation on the following tables to better understand their usage and related fields:
Notification Devices (cmn_notif_device)
Notification Device Variables (cmn_notif_device_variable)
Group Members (cmn_notif_grmember)
Notification Groups (cmn_notif_group)
Notification Service Providers (cmn_notif_service_provider)
Additionally, we have a few specific questions as below to ensure that it should not affect any platform functionality negatively.:
1) If we fill a group in the group field on cmn_notif_device table and add a phone number on this device and then use this device in the escalation path.
2) If we add a custom field to the cmn_notif_device table that supports storing multiple email addresses (current email field, only stores one email address)?
3) If no phone number is provided in the cmn_notif_device table, and only a user or group is added, why does it fail to trigger the alert from the on-call escalation?
