They normally give them Anglo sounding names (Buffy, Jody, Biff, George, Chad, etc..)to try and fool us. I have been able to get them to admit they are in Bangalore, New Delhi, etc..
The anglo sounding names are probably to make it easier for you to communicate with them. Not to fool you.
I am an Indian and I live in Canada and noone can pronounce my name, so I picked a nickname. It doesnt mean I am trying to fool people.
