Yes, I believe that is so. But still you get a problem if the NAT is
restricted, port-restricted or symmetric... The best would be to load
balance and always make sure that a given client is handled through a given
SER (REGISTER and INVITEs). That includes forwarding INVITEs from one SER to
another... OR you must load balance in front of your servers with one common
public IP.
