Oh yes. Like some others mentioned, I see it as an intrusion (unless I was expecting the call ahead of time). I also feel as though I'm intruding on others by calling them.
I had a telemarketing job once and was absolutely fine with reciting my script to strangers over the phone all day long. The only draw back was that, if I wasn't paying attention, I tended to start personal conversations off with the same script. (You don't know how many times I answered my personal phone with "Thanks for calling ____, this is....oh crap, I'm not at work...")
