Distro is able to read vacation time automatically on a rep's calendar as long as the rep has blocked their calendar using all-day busy events.
When a rep does this, Chili Piper will skip that user in the team round-robin to a different rep during this time.
If all reps happen to be on vacation at the same time, for example - January 1st - Chili Piper will ignore this vacation and still route the records to ensure none are lost.
