STAR can only point to APPLICATIONS. Build your day and night HUNT GROUPS, use EXTENSION LIST as member to cause all-ring. Then create 2 CALL ROUTING APPLICATIONs, one with DIGIT TRANSLATION/TIMEOUT to day HUNT GROUP, one to night. Be sure to remove the day and night recordings (defaults to voice mail intro). Then program the 2 CRAs into your STAR as destinations. That'll do it! Remember that you can put additional steps in the STAR for holidays, as long as they're above the regular hours step in the list.
