Hi,
Yes, the call attempt is timed out.
So, destination will be added to "dns" list even if dns was never used
to route this request? In other words, dns based failover is done
even if the r-uri contains IP (and not domain name)?
Thanks
Daniel

Hello Daniel,
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.
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.

Hi,
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?
Here is what i do (public ip replaced by me)
1. INVITE request received with
sip:0852281...@sip.mydomain.com;user=phone
2. I do some custom logic to route from db-saved destinations
3. r-uri rewritten to sip:087123456@10.10.10.10:5060
4. 10.10.10.10 offline - 10.10.10.10 is added to blacklist.
From the config, involved lines:
avp_db_query("SELECT dest_ip from my_forward_table where
number='$rU'", "$avp(result_dest_ip)")
$var(toruri) = "sip:" + $rU +"@" + $avp(result_dest_ip);
$ru = $var(tovururi);
t_relay()
From command line
> opensipsctl fifo list_blacklists
List:: dns owner=17 flags=6
Rule:: flags=0
IP:: 10.10.10.10
Mask:: 255.255.255.255
Proto:: 1
Port:: 5060
Expire:: 1474

Hello Daniel,
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.

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