Imessage for iPhone? Is the phone off?

Ok so basically I know that when you text an iphone to iPhone it will says "message delivered" and if the phones off, it says sent as text message. So when I call this person it goes straight to voicemail. (As if the phones off right?) but yet I text and it says message delivered as if the phones on. Anyone know what's going on? Cuz I always assumed if the phones off it wouldn't say message delivered.
