After Hours - Issue with lines not forwarding

I have our company hours set at 8:00am-5:00pm (weekdays). The IVR settings for both company hours greeting and after hours greeting is set to bypass greeting and and go to our receptionists extension. The call handling for this user (receptionist) is to ring their extension during User Hours and unconditional forwarding to an on call cell phone for After Hours. When I call our main line at 5:01pm, the call immediately forwards to the on call cell phone. When I call our main line at 7:30am, the call rings our office and NOT the on call cell phone. I have checked every single setting I find when searching for after hours call forwarding in the community posts and it appears I have everything set correctly. What am I missing? We are a 24/7 company and need all phone calls answered.
