Does anyone work in a role where you have to take phone calls all day or in a call center position?

Does anyone work in a role where you have to take phone calls all day or in a call center position? If so? How do you like it? Or if you’ve worked in a heavy phone position at one point in your life, did you enjoy it? I want to face my stutter by putting myself in challenging predicaments. *For reference, I have a mild stutter. Moderate whenever I’m super stressed or nervous.
