On the positive side you won't have to go through a lot of frustration
getting the fritz working.

In summary using an analogue adaptor on ISDN rather defeats the purpose of
ISDN."

You are absolutely spot on. I am hesitated by the sheer amount of configuration with the ISDN driver.

The actual implementation is actually even a bit of complicated. The ISDN is used primarily for internet connection and voip from an Australian provider. In that case I need to use whatever driver to intiate dail up to the internet. Will it be isdn4l in this case. Now if and when internet is down for whatever reason, asterisk can still perhaps use the capi driver to connect calls.

I don't have much experience in isdn at all. I am not sure where such setup can be done simitaneously. It would be nice if someone can point me to the right direction.

The Telstra connection already come with Nt1 +11 modem and I have already got pretty good doc to set it up with redhat 9.0. So I don't have to worry about isdn stuff. I wish to go the correct route which is using Fritz card to do this but I am afraid it is not possible.
