when i called i got through to a person. and i looked at quark or skytechnologies (cant remember wich) website for the number.

That means the number change is real recent. Maybe it's just a transitionary period for them.

They have always used a cellphone line for the US branch. That way the man in charge can answer when he is out of the office. No worries.

I do hear they have been developing some new products.
