I'm not anxious about it per say but I'd prefer not to speak over the phone if possible. I find it a nuisance and chore more than anything. If you sit down and think, what would be the worse things about speaking on the phone?

To answer that question for me, it was my "phone voice" and that I wouldn't know what to say. As far as the voice, I was always taught by people I thought knew better that you have to sound overly proper on the phone which made me more self conscious. When I worked at a call center and co-workers where speaking with their natural normal voices, I loosened up a lot. As for not knowing what to talk about, I think being at work were you have somewhat of a script makes it easier. I just started breaking all phone conversations into a kind of script and it's helping. If it's a personal call to a friend, my boyfriend, a more distant family member I make a mental list of several things to talk about.
