What does this mean? How do you do this?

If the endpoints communicate directly to a sipserver and they have different 
adresses, a router/firewall/nattranslation will not match the traffic from any 
other adres to the translated port. 

You could try branching to the other kamailio instance on failure to solve 
this. 

Or you could try to use the socket column in the location table to figure out 
if the invite needs to be handled localy.

Or you might be able to abuse Path on registration (by inserting a Path header 
manually)
