[OpenSER-Users] OpenSER Sending 473 filtered destination

Hi Vikas,

This reply is internally generated by the blacklists core - the 
destination IP address was blacklisted (maybe due a 50x or timeout 
previous response). This is a self-protection mechanism to prevent 
sending requests to destination already detected as unresponsive.

You can disable this by setting:
    disable_dns_blacklist = yes

Regards,
Bogdan
