[Asterisk-Users] OT: BRI ISDN question

[Iain Stevenson]

I would seriously consider whether to use a passive ISDN card or not.  In 
general reports of ISDN cards indicate significant issues with delay and 
echo.  My experience with a (very) cheap ISDN card and BT ISDN2e conforms 
to that.  ISDN is OK if you want to use asterisk as an answering system but 
not so hot for live calls.
