[Asterisk-Users] ISDN BRI with DDI support

[Jakob Strebel]

Maciej,



>and what about "AVM FRITZ! card PCI v 2.0" or "AVM ISDN controller C2" ?



I am using AVM Fritz PCI 2.0 It works fine. (I just put it in service some 
days ago. Asterisk runs stable with it)

>Am I need active controller?

As far as I remember I heard once that the active  DIVA Cards do echo 
cancellation. Can anybody comment on this?
