Yep, I worked five years of Internet tech support - I still do not like taking one-on-one calls with people. I'm usually fine with being in a group call generally, because the focus isn't on me to drive the whole thing forward all the time, along with a few other reasons.

Not to mention, it's not even just on a physiological level either - it wasn't really all that long ago where I was on a pay-as-you-go phone plan where phone calls absolutely would add up if I spoke with everyone over the phone instead of text (which no one in my circle uses regular SMS so texting basically didn't cost me anything).
