Hi, for a local reply (e.g. 408 on request timeout with dns failover) t_should_relay_response() and t_pick_branch() is called - which uses t_reply.c 1190 rpl = t->uac[b].reply; to check for FAKED_REPLY in get_prio(). But (that's the problem), this does not work for the t_should_relay_response()-run of a local_reply()-branch. The reason is, that store_reply(), which sets the necessary value: t_reply.c 1663 if (rpl==FAKED_REPLY) 1664 trans->uac[branch].reply=FAKED_REPLY; is called too late (after t_should_relay_response()): t_reply.c, within local_reply() 2062 reply_status=t_should_relay_response( t, msg_status, branch, 2063 &local_store, &local_winner, cancel_data, p_msg ); 2064 DBG("DEBUG: local_reply: branch=%d, save=%d, winner=%d\n", 2065 branch, local_store, local_winner ); 2066 if (local_store) { 2067 if (!store_reply(t, branch, p_msg)) This can lead to miscalculation of branch prio values.
