[分享] 請問這種網路電話的市場接受度?

I just saw the Cisco IP Phone 7910 today in my class.....however it requires same phone on both sides and real IP.
  
Do you test the quality from U.S. by using low-end DSL (384/64) to Taiwan?  Is there a trial period so we can return if the quality is not as good as phone cards.
  
thanks
