You can bro. I've been working in a call centre full time for the past 10-11 months. It's been my first and actual job at full time with a stutter. Some days I feel like walking out and calling it quits but I know that has no benefit to me. As long as my managers understand I have a stutter and think I'm capable of doing my job, I'll remain in it for the next couple of years until I move on to a job I actually want. Some days will be harder than others and you won't want to speak at all but you gotta keep at it !
