After the second attempt that Kamailio sends a call towards an ip address and gets a negative sip response say 503, kamailio will block that ip route for approx 4 minutes and sends 401 unauthorized immediately to the sip client. That ip route can be a gateway which is sending a negative reponse for certain destinations only and this may be due to a problem which is beyond the gateway itself; so I want to avoid blocking the complete route automatically. It appears that, in version 1.5 the route gets blocked for a longer period. Appreciate any help. Thanks, Karl

Hi,
I have always used the global setting disable_dns_blacklist=yes so as to avoid openser from temporarily blocking a particular route that may return a negative sip response such as 503.
I am now planning a migration to kamailio but the feature does not seem to be working. I have tried both kamailio 1.4 and also 1.5.
Since Kamailio 1.4 (perhaps since OpenSer 1.3) this option is dissabled by default (disable_dns_blacklist=yes).
What do you mean with "it doesn't work"?
