If you have following:
UA A ====> Kamilio 1
UA B ====> Kamailio 2
With path you just make sure that all calls are routed to that server where
UA initially registered.
So if UA A is calling UA B, call will go in such way: UA A=> Kamilio 1 =>
Kamailio 2 => UA B.
I hope I answered your question.
With kind regards,
