I work in IT, and it's all too common to talk to tech support reps based in India, Malaysia, Costa Rica, etc. They all speak English, but I am much more used to Indian English accent/dialect then Malaysian or Costa Rican. It depends though. Sometimes you get an Indian person with excellent communication skills (regardless of accent), and sometime it is just hard to understand. In my opinion, it is not the accent, but the cultural difference which influences the expression of language.
What about people in France, Germany, China and India? Do they get to speak with locals, or are their calls routed out of the country too? I am assuming Indian tech support is all in English.
