Was 'Short' on Phone With HR, How Do I Recover?

Dear Experts, I just found out I didn't get my dream job. I had 3 interviews (1 with HR, 1 with department heads, 1 written test) and they even grilled all of my references. I received a phone call with the news and was very short on the phone since I was in utter shock. What do I do now? Should I e-mail my contact in HR, should I e-mail the dept heads? I still want to be considered for any other positions at the company. Who should I follow up with and what should I say? Got a career question you'd like answered?
