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:[email protected];user=phone
2. I do some custom logic to route from db-saved destinations
3. r-uri rewritten to sip:[email protected]: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

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:[email protected]: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
