The Call On-Call Technician Flow action saves its phone tree inside each Flow. When on-call changes hands, an admin has to open every Flow that pages on-call and rebuild the tree by hand. Two problems this causes for us: Every shift change means several edits. We page from more than one Flow (after-hours emergency calls and RMM alerts), so the same swap has to be made in each one. If one Flow gets missed, the wrong tech is called overnight and the actual on-call tech never hears about the emergency. We run every shift with a primary and a backup. Each change means swapping two people, in the right order, across every Flow. The Active switch on each number helps for a short absence, but it doesn't replace keeping the tree current. Requested change, configured in Admin under Workspace alongside the time zone, office hours and holiday closure settings, and used by the Voice On-Call Flow action: A shared on-call schedule kept outside of Flows. Each shift has a start and end time and a repeating rotation, using the workspace time zone. Ordered roles on each shift, at minimum Primary and Backup. Each role holds the member, the number to reach them at, and max attempts. A phone tree option on the Flow action to use the on-call schedule. At page time, Thread calls the current Primary, then the Backup, then any fixed fallback numbers added after them (for example, a service manager). Overrides for shift swaps and PTO that don't change the base rotation. An internal note on the ticket naming who was paged and which shift they came from, plus a view in Admin showing who is on call now and who is next. This would let the phone tree follow the schedule automatically, with no Flow edits at shift change.
