Gradwell IAX incoming trunk problem

Hello,
I am trying to set up a Gradwell incoming IAX trunk with Trixbox 2.1.

Gradwell asks for a IAX destination of the form, IAX2/username:secret@asterisk_ip/pstn_number.

I set up a trunk in trixbox with the username as the USER context, and the following incoming settings:

allow=alaw
auth=plaintext
context=from-pstn
disallow=all
host=193.111.201.100
secret=*****
type=user

where ****** matches the secret in the IAX destination given to Gradwell.

I also set up an incming route matching the PSTN_NUMBER.

When I dial the number from outside, with "iax debug" on, I get the following output before the call is disconnected:

Any ideas, anyone?

Thanks!

Hi First things first.

check that your setup matched the howto at http://www.gradwell.net/support/trixbox-iaxin
the cause code is for NU ie number not found so its a context or number matching problem.
