> Doctor's offices and schools are notorious for using the caller ID "blocked." I let them hit voicemail.

My doctor's office won't leave messages, and appears to have about 20 minutes a day where they pick up the phone, so, if I don't pick up when they call, then I can't talk to them. (I know, I know, get a new doctor. But this is my third try to find a specialist who's willing to go beyond "here are some easy suggestions that you've already told me don't apply to you," and there are only so many battles that I can pick before I just run out of specialists entirely.)

You can thank HIPAA for that. Under the Privacy Rule medical information has to be guarded. While I have seen some practices let you indicate on the patient forms that you allow brief or full voicemail, many won't do it as there's no one to confirm their name and DOB. Even the fact that you are a patient at a clinic can be protected health information (for example getting a call from a women's health clinic or drug rehab center that doesn't block caller ID can be compromising).
