Hello Folks,
I looking to migrate a pbx from one server to another. The original server has 
this ISDN card:
 
00:00.0 ISDN controller: Cologne Chip Designs GmbH ISDN network Controller 
[HFC-4S] (rev 01)
 
The new server:
00:00.0 I2O: Digital Equipment Corporation StrongARM DC21285 (rev 04) << AVM 
ISDN Controller C4


Now I'm not fully aware of both's cards functions since the manuals are very 
brief. What I heard is that the later card does not support some NT commands 
what I might going to need at this migration. I can't really say if one card is 
"better" than the other one.
Unfortunately the two uses completely different drivers. The first card uses 
dahdi, the second uses capi. I want this migration go as smooth as possible 
with the least downtime so I looking for some help
maybe someone has more experience with these cards.
 
I also read something about CAPI uses completely different dial plans.
So all the Asterisk configurations are migrated from the old server to the new 
one.

By following this guide:
http://www.asteriskguru.com/tutorials/avm_c4.html

I have the C4 modul loaded. My asterisk box is Asterisk 1.6.0.26-FONCORE-r78 
(Trixbox).

How can I see that this C4 card is really working from asterisk?

What is the difference between the chan_dahdi.conf and chan_capi.conf?

Can't I just tell it somewhere to use the new card and I don't have to touch 
the existing dialplans etc?


Thanks!
