I am looking for a way to setup Alert Central to use a single On Call Calendar regardless of the group that the alert was routed to. I have multiple groups setup that send the alerts to the correct region of our company to notify the person in that region and then others that need to know. But we do not have enough IT staff to have a separate On Call rotation at each region or group. So I am trying to setup a single On Call rotation that uses the techs in all regions during On Call hours. What is the best way to set this up.
For now, there are no shared calendars or possibility to escalate to another group (these options will probably suite you).
If you have a group of people who should receive all the alerts in spite of the assigned group, you'll have to add Default Calendar with the same staff to every group and then duplicate their schedule on Calendar for every group also.
Unfortunately, now there's no another way to cover your case.
