[asterisk-users] isdn cross-over ...

[Zoa]

Any card using this chip:
http://www.colognechip.com/isdn/controllers/frame-hfc-s-usb.htm (=usb 1 
port doing TE and NT mode)

This would be the cheapest way to test them, hook the 1 port up to the 
asterisk server and call an echo application, then try the same with the 
second one.
I dont know any 1 port cards that do NT mode.
