As anyone been successful in getting Asterisk working with SELinux enabled?
I am building a new system with CentOS 6.0 and I am required to have SELinux enabled as well a iptable rules. Any help in getting a SELinux policy for asterisk in place would be greatly appreciated.

Yes. No special steps needed for source install of on Centos 5.3. However, I would tend to the view that Asterisk should be run on a dedicated machines, for which SELinux offers no benefits.
