I know for a fact that I am not a telephone person. I greatly dislike both answering the phone and having to speak on it.
Don't get me wrong, it's not a phobia, just a medium of communication that doesn't work well for me personally. I prefer being able to see someone, when speaking to them.
So take it as no surprise that my cell and home phones are often filled to maximum number of messages and accepting none further.
A friend today reminded me to empty my phone messages so more ones could be left.
I think the real lesson is that I should answer my phone a little more often or get a secretary.
