I have a similar fear of telephone interviews and have had a number of them recently. I find them to be extremely anxiety provoking. One thing I would recommend is to disclose that you stutter early on. Most of my recent interviews have been panel interviews (meaning that I am on a speaker phone and a room full of 3-4 people are listening on the other end). I think it breaks a lot of the tension to disclose early and sometimes use humor... I will often say that stuttering + interview anxiety + speaker phone is not a great combination. Hope this is somewhat helpful :) Another thing I would recommend is to get comfortable on the phone before the interview. Make a bunch of calls to friends, telemarketers, your bank, it doesn't matter. Just log some time on the phone before the interview.
