I have an anxiety disorder (GAD), so here's some personal anecdote... My fear of phone is more among the line of "I might miss something _very_ important if I don't answer immediately." Unsolicited phone calls, and sometimes non-important phone calls make me very annoyed/angry to the point that sometimes I started yelling at caller over the phone. I know I shouldn't. However, at the same time, I'm also scared of answering the phone from known or unknown callers since I _don't know_ what they're calling me for. Even such call is expected, I always assume they're to tell me a bad news. I'm fully aware it's absurd, but it's uncontrollable.
