Yup; got a call from NCIS once (not the show, the real thing). The agent was more than happy to tell me what office she worked for and her name. I then looked up the number on navy.gov independently and got transferred back to her.

Fun fact: it was over a guy who was stealing equipment from the Navy and selling it online. Turns out they didn't want the equipment back (since it couldn't be re-deployed for security reasons). They just wanted me to testify against him. I believe he ended up pleading out once confronted so I never ended up testifying.
