Ok I found the problem, i wasn;t including the module group.so, thats why i
receievd the below error.
This is my issue now:
budgetone with stun server set as fwd's , this phone works fine
All others behind nat are broken, cant even dial to the asterisk system.
If I use a live ip on a phone it works phone.
All i want to do is allow nat users to receive calls, i seem to be heading
round in circles.
My personal config allowed for nat users to call the asterisk pabx & live ip
phones, now the cfg
from onsip allows only calls between live ip users.
When trying to call from my cisco 7940 which is behind nat i receive this
via ngrep:

Subject: RE: [Serusers] Nat incoming call
Ok, so ser worked for a few minutes in the following way:
Me on live IP calling a nat user, their phone would ring, however me the A
party got no ring, after 20 seconds I received NU tone.
NAT user is able to call me with no problem.
Then things just died and now when I run ser I get the following:
