Business Phone System for Cell Phones? - automated phone answering system

I am a high school student and my own business. I have a problem because I have to answer to business calls, phone, and I'm at school during office hours.

I've heard about the set they provide their own telephone services business to voicemail and call forwarding on your phone.

Does anyone know of a service like this or any other solution to my problem? Thank you.
