[Kamailio-Users] disable_dns_blacklist

[Karl Smith]

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

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"?
