We are a US based company and we were supposed to have a conference call with someone in China last week, and they were unable to connect to the bridge. They tried the number several times on a landline phone and kept getting a busy signal each time they tried. When they tried on a cell phone, they were told the number did not exist. If there is a new number, can you please provide what that number is. And if there is a problem with the existing number, when will it be fixed?
