@editor75 AR doesn't have a US call center location.

They used to have a permanent Skype number that they used to contact their writers.
However, the number was one way in the sense that they could only call out but nobody could call in.
Nobody would pick up the phone on the other end. Instead, you had to leave a voice message with your instructions for them and then, if they felt clarifications were required, they would then call you back.
This was their preferred method of communicating with their writers and clients for a long period of time. Lately though, they have been using rotating phone numbers.
My friends who still work with them say that they get numbers coming into their cellphones that seem to be pinging from all over the world.
They get calls from number in the U.S. or Singapore. So my guess is that they purchased a software that masks their real phone numbers.
I don't know what game they are playing but if their writers and their clients can't call them, I don't see how these projects ever get done these days.
