Trixbox 2.6.1 and B410P

Hi,

Does anyone have sucessufly installed this isdn card on CE v. 2.6.1?
I've followed the instructions in this http://trixbox.org/wiki/chan-misdn but I still cannot make or received any calls.
Just one ISDN Line on connected on card port 1 and the led is solid red.
I think the problem is with the trunk creation and with misdn.conf last module:

"
[isdn]
ports=1
context=from-pstn
msns=*
Adding mISDN as trunk (with the same configutarion file):
Create a Custom Trunk with Custom Dial String like this:
mISDN/g:isdn/$OUTNUM$

(note that [isdn] group in config is being called here...)
"
Can someone please tell how to create the correct trunk and how it is related with misdn.conf?

Thank you a lot!
Regards
Rui
