[Frage] fritzbox as ISDN trunk to asterisk

[vortex1]

i have an installation that i am using fritzbox 7170 with an ISDN and 3 numbers in total. each number is in one of the analogue ports of the router. the requirements has changed and in the office we need 4 numbers in total, fax to email, IVR, and many functions that i can offer from asterisk. my question is if there is a way to get the isdn to asterisk by sip trunk and how to configure it. i would like to have only one registration between asterisk and fritzbox. all numbers to go through this registration.
it will save me a couple hundreds of euros for an ISDN card for the asterisk

No way with only one registration, as discussed quite a few times already. You need an own registration for each of the MSN.

Some days ago I successfully set up CAPI using this howto, and this patch due to stripped DID. Works great for me.

hi. i am using debian and i did not have any luck with those links.
what i did up to now was to:
-enable capi over tcp in fritz
-create a trunk in freepbx for that extension 622 (assigned from fritzbox for fax)

faxing does not work. phone calls are ok though.
