That's good to know, but considering the response from Digium on the 
TDM400 ( try another motherboard) when there didn't seem to even be an 
int. sharing issue, the card just couldn't be seen at all , and the 
support I received from Sangoma on a recent FXS issue that was resolved 
within a few days, I would tend to go with Sangoma for the T1 card, if 
and when I have the need.
