Multiple oncall issue and user alert notification policy

Hi,

Some background.

User A is setup with Alert Notification Policy:

1. Primary email usera@company.com

2. Send to secondary email (email2sms)

User B is setup with Alert Notification Policy:

1. Primary email userb@company.com

2. Send to secondary email (email2sms)

We have an issue when user A and user B are both oncall. When an alert is triggered only the primary emails for both users get the alert emails. The secondary emails does not even get notified. Meaning the alert notification policy for each user is not followed, however when one person is oncall, then the alert notification policy is followed.

So is this normal or a bug?

Thanks,

Danie
