I am using a Traverse NetJet-S card with the ISDN4Linux drivers in 
Asterisk on my home firewall. I was using ISDN to connect to the 'Net, 
but I've just -- in the last couple of months -- managed to convice 
Telstra let me get ADSL provisioned. I decided to keep the ISDN line for 
voice, so I've got a personal number and a business number coming in the 
ISDN.

The only "problem" I've had is that I have had absolutely no luck in 
getting fax support working with the i4l driver and my questions on this 
list in regards to that have gone unanswered on at least 3 occasions...

You can find the Traverse site at http://www.traverse.com.au/. Last time 
I checked they had a card for the US market (you'd need to email them to 
ask if the NetSpider works with I4L).

HTH,
Darryl
