CPL Reference
Allow Calls from Locally Registered Endpoints Only
In this example, the administrator only wants to allow calls that originate from locally registered
endpoints.

Block Calls from Default Zone and Default Subzone
The same script can be extended to also allow calls from configured zones but not from the Default
Zone or Default Subzone.
