Unlimited 'in state' calling plan

How do 800 number calls work with this plan? If the 800 number goes somewhere out of state, do I get charged by the minute? Don't know if this is a silly question, but I'd like to know before I start making these calls

I have this plan, and also had the basic BYOD adapter plan for $5 before I switched to the in-state plan. Toll-free calls do not count against any of your minutes they are always free. I got my service to mainly attend conference call at work (I was 100% cellular before). I dial into my conference calls on toll-free numbers. Having my VoIP line is definately better than sitting on a 1 hour conference call on my cell phone.
