Hi can someone please explain me how LCR works. Specifically, scenario: prefix 1514 handled by gw_1 and gw_2 all other prefixes handled by gw_3 1) Call comes w/ RURI = 1514111111. 2) load_gws is called. In the database, prefix 1514 is supposed to be handled by gw_1 and gw_2; 3) next_gw() is called. RURI is now 1541111111@gw_1 4) call routed to gw_1; gw_1 rejects call 5) we go to failure route and call load_gws() again -- [QUESTION: what happens here?? how does SER know that we need to replace URI w/ 151411111@gw_2 ] 6) next_gws() called. I assume call will go to 1541111111@gw_2 7) gw_2 rejects call. We again go to failure_route. Here again we do a load_gws(). [QUESTION: How does SER know that both gw_1 and gw_2 options have been utilized?? Does load_gws return an error here or does it load gw_3? ] My problem is that in my case, gw_3 is being used after gw_1 and gw_2 have been used. As per my understanding this should NOT happen since prefix 151411111 is not handled by gw_3. Any pointers appreciated.. Running ser 0.9.6
