Gigaset phones default to a DNS load balancing mechanism to help reduce upstream server congestion. This mechanism will randomly select between DNS 1 server and DNS 2 server upstream servers to send DNS queries to.
When dns_load_balance is disabled, this will remove the randomisation and respect DNS 1 and DNS 2 order.
ie All DNS queries will be forward upstream to DNS 1 server if local cache does not have an entry. If DNS 1 server is unreachable, DNS query will be then sent to DNS 2 server.
