Sorry, it was an issue on my side.
By the way, I have debugged Sofia a bit and found that it signals this 904
w/"No matching challenge" when it fails to parse an authentication string
passed to nua_authenticate(). I think in this case the text should be a bit
more descriptive :)
But anyway everything works now, thanks again for such a nice SIP stack!
