Phone calls are where I struggle the most with phone calls. I had to call up the doctor a couple weeks ago and I could barely explain what was up with me. I managed to tell them I had a stutter at the start of the phone call though. I missed the call back so had to call back and explain that I missed a call. I got the whole “hello, are you there?” thing because of blocks. Phone calls are awful but declaring your stutter at the start definitely helps
