Greeting Injection support for Permit and Block Actions: You can now inject greetings without blocking calls - for example to inject a Coronavirus greeting to every call into your cluster.
You can use this by typing the exact name of the greeting in Callmanager Announcements into the rule, shown below.
Permit action - you can now have policies that do not block.
Default action - calling and called numbers can be blank to match all calls in a policy.
