Disable DNS functionality on Asterisk 12.3.2 with pjsip

Hi,
I’m using the latetest Asterisk version with pgsip stack.
On incomming call the asterisk look for the ip-addr of itslef from the DNS.
When I use sip.conf there is parmeter that disable this behavior:
srvlookup=no
On the change log I see its now automatically enabled.

Is there a way to disable it ?

Thanks,
Yaniv
