FRITZ!Box Fon WLAN 7050 and Asterisk

Dearl all,

I am new to Asterisk…I install AsteriskNOW on a laptop and I would like to use a FRITZ!Box Fon WLAN 7050 like a ISDN Voice gateway.

This is the little scenarios:

  1. One Aterisk Server
  2. One FRITZ!Box Fon WLAN 7050 connected witj the same lan of the Asterisk Server and with my ISDN line
  3. Two Personal Computer with a softphone installing on.

I register the Fritz!Box to the Asterisk with as SIP account and I be able to call the Fritz!Box with a softphone and then I can call with a “call diversion” with my ISDN line.

It’s possible to configure Asterisk and the Fritz!Box to create a Calling Rule that permit me to redirect the external phone call directly to the ISDN line?

Thank you in advance!
