Good for you!! I also took the plunge at a call center job back in 2008, it was right when my stutter was getting pretty bad again. It was rough at first I'm not going to lie! But after awhile I started gaining more confidence and it actually improved my stutter a lot!! I had a lot of challenges along the way but ended up training new hires after killing it on the phones. Props to your for going through with it, and feel free to ask questions about tips or tricks if you start having a hard time.
