what I want to do (in a non-comercial envorinment):
- Setup a PBX wich is connected to an ISDN Line (AVM B1)
- Use VoiP- or Soft-Phones on our LAN, maybe personal Mailboxes
- Make all outgoing calls via ISDN
Can I do this with Asterisk and an AVM ISDN Card? What Modules/Additional software/hardware would I need?
