Hi All,
We have recently installed an openSER for internal use and are looking
at some '473 destination filtered' error responses for INVITEs and
SUBSCRIBEs. I haven't looked in detail at sources yet but from the
header file I can see that 473 error response corresponds to some '
E_IP_BLOCKED' error condition.
Anyone who can help me understand what this error condition means?
Openser 1.2 generates a 473 error in case all target destinations are
temporarily black-listed. You can disable this behavior with
disable_dns_blacklist=yes
DNS black-listing is further described at:

Thanks,
Anshuman
