[App_rpt-users] Anyway to detect recent activity

I'd like to make some scripts of mine a little smarter. Is there any way to determine if the node has been active within the last ID timer window of time. E.g. instead of firing a *speak the time at the top of the hour* script, I'd only like to happen if the node is inside the countdown timer for a final ID. This is how most of the configurable external controllers work. Then once the final ID fires, the repeater is quite until activity again, then resumes its scripts, etc until no activity after its final ID time countdown. Just curious if there are any provisions for similar either internal or external (environment variable, polled value from asterisk -rx, etc) Alan
