Hi all,
I want to build in my small company little PBX with asterisk.
I have one ISDN BRI link with DDI preselection and a couple of analog
phones.
I need somethink like this
+----------------------+----------- phone 1 (extension 1)
| LINUX with ASTERISK +----------- phone 2 (extension 2)
| |
ISDN BRI DDI | +----------- phone 3 (extension 3)
-------+ |
| +----------- phone 4 (extension 4)
| |
+----------------------+----------- phone 5 (extension 5)
So, my problem is, I'm lost in lots of abbreviations, and I have no idea
which pci card to select.
I know, I need one ISDN BRI DDI card for incoming isdn line
and some pci cards with RJ11 for analog phones.
1) can anybody help me to select correct pci cards?
2) can i use more then one isdn cards (connected together) if I need
more the 2 simultaneous phone calls?
THANK you very much.

You have to move to PRI if you want more usable lines. I'm not totally sure but this would be true enought.....

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)>what does it mean active vs. pasive controller, where is difference? >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? Jakob
