405-755-1515

True...from Mercy Hospital.  Actually knows a person that calls from this number.

That's good to know it's probably from the hospital!  
Why don't they leave a message?  I don't like to answer numbers I don't know.  
I couldn't owe them money, so it's not like they'd be afraid of tipping me off that that's what they're calling for. I don't have family or anyone who'd use me as an emergency contact in OKC either.

405-600-1515 is the Mercy hospital switchboard.  All the doctors offices phone calls go through this switchboard, so the number they are calling from (the doctor's phone number) does not show on the caller I.D.  This is what the nurse told me when I called her and asked about it.

They keep calling my cell number and asking for my dad!
