I am trying out Asterisk v13 in beta repository. So far the basics seem to be working.
One thing that is missing from the beta repository are the asterisk sounds. They get removed when Asterisk v11 is removed.
Please add the sounds to the beta repository.
https://packages.asterisk.org/centos/6/current/x86_64/RPMS/
CE6 sound rpms will install on CE7.
It would be nice if g729 and sln16 sounds were available as well. There does not appear to be an RPM for that but the tar.gz files are located here.
