Call center job tips?

Call center job tips? Hey! I have been stuttering for 13 years now and I got a job where I make and receive calls and I have never done a job like that. I have called people in my old job before but never like call center type. I will have a script and not have a lot of people in there. I am determined to do this job well and not let my stutter stop me! I am just looking for some tips. Any feedback welcomed.
