I have a doctorate in Psychology. I do not ask people to call me "Doctor". My first name is fine. I get "Doc" sometimes, or "Doctor B" as a nickname, and that's fine too.
My employer wants me to identify myself in correspondence, voicemail greetings, etc. as "Doctor", but that is for their own prestige (what little there is to have) not mine.
I think "Doctor" rightly applies to all who have finished the highest level coursework in their field. Doctors of Medicine are "physicians", etc. But I do think introducing yourself outside of your work environment as "Doctor" is a little pretentious.
JMHO
