<div>So, destination will be added to "dns" list even if dns was

<tt>Hello Daniel,<br>
<br>
and your call times out ? or how is completed the call
attempt. Because, per RFC DNs-based failover should be
done if (1) transport error or (2) SIP error - timeout
or 50x replies.<br>
<br>
In this cases opensips will consider it a failure, will
try to do a DNS-based failover (if multiple IPs are
available) and add the failed destination to the "dns"
list.<br>

<div><br>
</div>
<div>Thanks, I somehow manage to get IP-addresses
that are never supposed to be looked up by dns
added to the dns blacklist. Is it someway I
accidentally cause lookup even when routing on IP?</div>

<div>Here is what i do (public ip replaced by me)</div>

<div>1. INVITE request received with <a

db-saved destinations</div>

<div>4. 10.10.10.10 offline - 10.10.10.10 is added
to blacklist.</div>

<tt>Hello Daniel,<br>
<br>
disable_dns_blacklist is used to store
failed IPs which were discovered via DNS
(NAPTR + SRV + A). Once an IP is
blacklisted, it will be blocked in all
cases, doesn't matter if calling via FQDN
or directly IP.<br>

<div> Hi, </div>

</div>
<div>(opensips 1.7.2)</div>
<div><br>
</div>
<div>I have </div>
<div>disable_dns_blacklist=no</div>
<div><br>
</div>
<div>Good: Blacklisting for
destinations that are discovered by
srv record but not responding are
working.</div>
<div><br>
</div>
<div>Bad: But I also get blacklisting
on destinations that are addressed
with ip-address. Ex <a
moz-do-not-send="true"
href="sip:087123456@x.x.x.x:5060">sip:087123456@x.x.x.x:5060</a>.
I was under the assumption that
routing by IP-address should not be
blacklisted (judging by the _dns_ in
the parameter name. :). </div>
<div><br>
</div>
<div>Is this the designed behavior am
I accidentally using dns for
IP-destiantions?</div>
<div><br>
</div>
