Call Policy is enabled and disabled using the Call Policy mode
option on the Call Policy configuration page.
To go to the Call Policy configuration page:

•

VCS configuration > Call Policy > Configuration

To enable Call Policy using the CLI:

•

xConfiguration Policy AdministratorPolicy Mode

Call Policy mode options are:
On: Call Policy is enabled. If a CPL script has been uploaded,
this policy will be used. Otherwise, the policy configured using
the Call Policy rules page (VCS configuration > Call Policy >
Rules) will be used.
Off: Call Policy is not in use.

You must click Save for any changes to the Call Policy
Mode to take effect.

After you have enabled the use of Call Policy, you must
define the policy to be used. This is done either

using the

web interface

or by

uploading a CPL script

If Call Policy is on but a policy has not been configured,
then a default policy will be applied that allows all calls,
regardless of source or destination.

Configuring basic Call Policy using the web interface

The Call Policy rules page lists the web-configured call policy
rules currently in place, and lets you create, edit and delete
simple Call Policy rules without having to write and upload a CPL
script.
To go to the Call Policy rules page:

•

VCS configuration > Call Policy > Rules

You cannot use the Call Policy rules page to configure
Call Policy if a CPL file is already in place. If this is the
case, on the Call Policy configuration page (VCS

configuration > Call Policy > Configuration) you will have the
option to Delete uploaded file. Doing so will delete the existing
Call Policy that was put in place using a CPL script, and enable
use of the Call Policy rules page for Call Policy configuration.

To add a new Call Policy rule, click New. You are taken to the Add
Call Policy rule page.
To edit an existing rule, click View/Edit. You are taken to the Edit
Call Policy rule page.

You can configure the following Call Policy rule options:

Source pattern

The alias that the calling endpoint used to identify itself when
placing the call.
If this field is blank, the policy rule applies to all incoming calls
from unauthenticated users, meaning calls where the endpoint
making the call is not either:

•

locally registered and authenticated with the VCS, or

•

registered and authenticated to a neighbor which in turn has
authenticated with the local VCS

See the

Call Policy and authentication

section for more

information about unauthenticated users and Call Policy.
This field supports

regular expressions

Destination pattern

The alias that the endpoint dialed to make the call.
This field supports

regular expressions

Action

Whether or not a call that matches the source and destination is
permitted.
Allow: if both the Source and Destination aliases match those
listed, call processing will continue.
Reject: if both the Source and Destination aliases match those
listed, the call will be rejected.

Rearrange

Each combination of Source and Destination is compared, in the
order shown on the Call Policy rules page, with the details of the
call being made until a match is found, at which point the call
policy is applied.
To move a particular item to higher or lower in the list, thus giving
the rule a higher or lower priority, click on the and icons
respectively.
