I think it would be better to have both here.
I find it really useful being able to understand what they are saying, especially on a long distance line
I pay UK money to a UK company, so why should a foreign country benefit from the employment and money?
There is an argument that it is cheaper as they will work for less, but, if you take into account my comments above, I think that this is a false economy.
I wonder if VM get a special deal for all these long distance routed calls too??
