What do you mean you "disabled the resolver"?
I haven't play with this in a long time, but I think the /etc/nsswitch.conf file defines if you use /etc/hosts file or/and DNS for looking up host names, and might allow nis+ as well, but I can't remember.
So might want to check if you happen to have your hostname defined in the hosts file. Also seems people note that /etc/resolv.conf might be overwrite at boot based on using NetworkManager. So maybe your settings are being over written.

It seems that the Opensip 2.2 caches DNS queries !!!
Even after I disabled the resolver in Centos, the OpenSIPs seems to "remember" old queries. (eg. IP's)
after a Opensip restart, the old stuff was gone.
If so, how can I disable the DNS caching in the Opensips, I want the system to always make a new , fresh
