Thank you very very much, it works now!

Read this article, http://web.wenxuecity.com/BBSView.php?SubID=computer&MsgID=175039.

Also, when I call out using Line 2, it is still showing a random number on receiver's phone. I'm going to search WXC first to see if I can find answer myself.

Again, thank you very much for all your help.
