hello all again.
trying the third day...
my cfg is: http://pastebin.com/vMHd7kki

I need scheme like:

any_sip_device_on_internet_nated_and_not => kamailio ext ip (194.190.8.171) | kamailio int ip (50.0.0.1) => asterisk (50.0.0.10)

a do not need realtime configuration of asterisk.
I only need forward everything to asterisk. and after signalling will work, I need rtp too... but its the long way I think.

so how I must config kamailio that it doesnt answer 200 when I send register? 
it looks like sip device send register, kamailio fwd it, but answer to device 200. and than my device doesnt resend register normal.
