Can you please clarify for me why this is incorrect DNS configuration? I
had the following setup in mind when writing the question. 41520 IN   SRV     1 1 5060 41520 IN   SRV     2 1 5060

What this essentially means is that should be used
as long as it's responding. But this doesn't happen since it falls out
of the blacklist.
