Closed For Lunch...

Hello! 

I hope I explain this well enough...I work in an outpatient healthcare facility that is required to have after-hours connections to an on-call provider. I have no problem setting up the schedule for when our office is open, and routing to the provider overnight when we are closed. But I'm wondering if it is possible to have a different schedule/message that states we are closed for lunch without having to route to anyone?

Has anyone else tried to navigate this or come up with a creative solution if it is not straight forward? Doctors need a break, too.

Thank you!
