Eric, I am very aware of what you are talking about. However I am comparing two different computers connected to the exact same PSTN line in the US, using the exact same Digium TDM card. Huge difference in cpu's and bus speeds. * still needs to get the data from the TDM or X100P card and parse it internally before ringing the pbx extensions.
