[asterisk-users] About BRI / ISDN hardware. What to buy?

[Cosmin Prund]

I finally found a price tag for the darn thing, at around 500 euros I 
can handle it.
Qustion: Do they behave properly if I've got an other Digium TDM400 card 
in the system? How about installing two cards in the same server?
At the moment I've only got 1 ISDN line plus a few analog lines going 
into the TDM but in the very near future we might want to get a second ISDN.
