About Call Policy
You can set up rules to control which calls are allowed, which calls are rejected, and which calls are to be redirected
to a different destination. These rules are known as Call Policy (or Administrator Policy).
to a different destination. These rules are known as Call Policy (or Administrator Policy).
If Call Policy is enabled and has been configured, each time a call is made the VCS will execute the policy in order to

decide, based on the source and destination of the call, whether to:
■
proxy the call to its original destination
■
redirect the call to a different destination or set of destinations
■
reject the call
Note:
when enabled, Call Policy is executed for all calls going through the VCS.
You should:
■
use Call Policy to determine which callers can make or receive calls via the VCS
■
to determine which aliases can or cannot register with the VCS
Configuring Call Policy
The Call Policy configuration page (Configuration > Call Policy> Configuration) is used to configure the VCS's
Call Policy Mode
The Call Policy mode controls from where the VCS obtains its Call Policy configuration. The options are:

■

this takes precedence and you will not be able to use the Call Policy rules page; to use the page you must first delete
the CPL script that has been uploaded.

If Local CPL is enabled but no policy is configured or uploaded, then a default policy is applied that allows all calls,

The Policy service option is used if you want to refer all Call Policy decisions out to an external service. If you select
this option an extra set of configuration fields appear so that you can specify the connection details of the external
service. See
