Asterisk 11.2.0 is now available and I have prepared RPMs for Fedora 17 & 18 as well as Enterprise Linux 6. These RPMs include updates from branches/11 of the upstream Subversion repository.
The RPMs are in the mss-testing channel of the Fedora & Enterprise Linux RPM Repository so as to not conflict with upstream Asterisk RPMs from Fedora, Red Hat, CentOS, etc.
