spa 3000 in asterisk and port 5061

[binary_dreamer]

Hi.
i am using spa3000 for sometime now with my elastix server and i am happy.
I am facing a new installation where i did install asterisk in a fritzbox 7140 (192.168.1.90) and it works smoothly getting the fxo to work, all in sip port 5061. Now i do need to get in that fritz 7140 to get as well a spa3000 to get the gsm gateway on my fritzbox, to install disa. there is something wrong in my config and i cannot make it work with fritzbox at port 5061.
here is my config:

sip.conf

[SPAGSM]
host=192.168.1.102
port=5062
type=peer
canreinvite=no
context=from_spa
dtmfmode=auto
nat=never
disallow=all
allow=alaw
deny=0.0.0.0/0.0.0.0
permit=192.168.1.0/255.255.255.0
#######################
extensions.conf


[outbound]
exten => _[18]X.,1,Dial(SIP/SPAGSM/${EXTEN})
exten => _[18]X.,2,Busy(3)

[from_spa]
exten => s,1,Answer()
exten => s,n,Authenticate(123)
exten => s,n,DISA(no-password,from-internal)
exten => s,n,Busy(3)

On the SPA in the dial plans i do have [email protected]:5062

could someone spot what it is wrong?

When i am calling from my mobile to the mobile on the spa, on the info page of the spa3000 i can see who is calling.
But in the asterisk on the fritz i did not receive anything at all!
