Asterisk 11 DNS SRV INBOUND ROUTING

Hello,
could you please provide me any tutorial or help to configure Asterisk 11 for Inbound DNS SRV routing instead of IP routing? do i have to configure also bind 9 in order to use this service as my server has a reverse name pointing to my public IP address.
I will be thankfull if you could give me a hand.

Best Regards
