After some advice - work related

After some advice - work related Hi, I’ve had a stammer for my whole life, ever since I’ve been able to talk. In my job, it involves making calls to customers a few times a day. A few times lately I’ve been struggling to say the introduction - company name and also my own name. Does anyone have any advice of getting around this? It’s definitely stressing me out quite a lot with it happening more often. My stammer consists mostly of blocks and facial tics (grimacing etc)
