Thanks for the reply. I am afraid of buying something, putting my hopes and relying on something that just does not work in China. Not the technologies fault, somethings just don't jive in China.
I had a VOIP phone that works great in North America but when we moved to Taiwan it did not work nor did it work in China but did work perfectly in Hong Kong. Spent hours with tech support and reconfiguring settings and we all just gave up. I realized that cause it works in one place is not necessary work in another place.
Don't want to make the same mistake again.
