Did any one had any problem with this?
I have a test setup where I have the following directives for dns caching:
use_dns_cache=yes #enabling DNS caching
dns_cache_del_nonexp=yes # deletes entries if the memory is
becoming full
dns_cache_flags=0
dns_cache_gc_interval=120
dns_cache_init=on
dns_cache_max_ttl=3600
dns_try_ipv6=no # yes if you want the lookup to be
for IPv6 also
dns_try_naptr=yes
despite the fact that I have *dns_try_ipv6=no* kamailio sends a AAAA
request to the DNS server.
This is an extra request in a case where it seems not to be needed.
Also, it seems that a NAPTR request is not sent - I need to investigate
more, being just a hunch for now.
All the best
