Its not for the person on the other end.
I used to do phone tech support, and:
1. Lots of my female coworkers would end their shifts in tears because men would yell at them for no reason. A male voice would absolutely make the job more bearable for them.
2. Singaporeans hate Australian accents more than anyone over here hates indian accents. I had a nearly 100% strike rate with singaporeans demanding local tech support, calling me names and hanging up.
