Is this sentence correct?

HI, I wrote the sentence below but I am not sure how it sounds on native ears.

Every single person who calls at home, after hearing my voice and my name, gets confused and asks me if I am a boy.

I am wondering if there is any way to rephrase the underlined phrases

since it feels like there is a room for improvement.

As for "calls at home", is it also possible to omit "at"? Which one would sound better?

As for the second underlined phrase,

I want to rephrase it to mean something along the lines of "I am mistaken for a boy" or "people mistake me for a boy"

Are these alternatives acceptable?

I would greatly appreciate it for any help I could get.
