Hello Alex, 
I switched to aliases method, but in case like this, 

AU ----> Internet ---> Kamailio ----> Asterisk 
AU2 <--Internet <---------| <------------| 

Call between two extensions not working, because kamailio mark as external domain and LOCATION not saved, but even if I save location I see in kamctl ul show more then 5 records for each AOR. 

Slava.
