Call Policy
Configuring Call Policy using a CPL script
Overview
You can use CPL scripts to configure advanced Call Policy. To do
this, you must first create and save the CPL script as a text file,
after which you upload it to the VCS.
For information on the CPL syntax and commands that are
supported by the VCS, see the
CPL reference
.
Viewing existing CPL script
To view the Call Policy that is currently in place as an XML-
based CPL script, go to the
Call Policy configuration
page (
VCS
configuration > Call Policy > Configuration
) and click the
Show Call
Policy file
button.
If Call Policy has been configured using a CPL script, this will
•
show you the script that was uploaded.
if Call Policy has been configured using the
•
Call Policy rules
page, this will show you the CPL version of the call policy rules.
if
•
Call Policy mode
is
On
but a policy has not been configured,
this will show you a default CPL script that allows all calls.
You may wish to view the file in order to take a backup
copy of the Call Policy, or, if Call Policy has been
configured using the
Call Policy rules
page you may want
to take a copy of this CPL file to use as a starting point for a
more advanced CPL script.
If Call Policy has been configured using the
Call Policy
rules
page and you download the CPL file and then upload
it back to the VCS without editing it, the VCS will
recognise the file and automatically add each rule back into the
Call Policy rules
page.
About CPL XSD files
The CPL script must be in a format supported by the VCS. The
Call Policy
configuration page allows you to download the XML
schemas which are used to check the script before it is uploaded
to the VCS, so you can check in advance that your CPL script is
valid. Two files are available:
Show CPL XSD file
Downloads the XML schema used for the CPL script.
Show CPL Extensions XSD file
Downloads the XML schema used for additional CPL elements
supported by the VCS.
Uploading a CPL script
To upload a new CPL file:
Go to the
1.
Call Policy configuration
page (
VCS configuration >
Call Policy > Configuration).
The CPL script cannot be uploaded using the command
line interface.
From the
2.
Policy files
section, in the
Select the new Call Policy
file
field, enter the file name or
Browse
to the CPL script you
wish to upload.
Click
3.
Upload File
.
Deleting an existing CPL script
If a CPL script has already been uploaded, a
Delete uploaded file
button will be visible. Click here to delete the file.
