[Serusers] why would a client behave differently for nat onoutbound as opposed to inbound

Hi

Thats wat i thought, but since the same ser.cfg is being used :-) why 
wouldnt HT be proxied, surely the ser.cfg reads the INVITE and processes 
it the same for HT and for xlite, why would it differ based on the 
client used.
