Call Policy
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 Show Call
Policy file.
•
If Call Policy has been configured using a CPL script, this
shows you the script that was uploaded.
•
If Call Policy has been configured using the Call Policy rules
page, this shows you the CPL version of the call policy rules.
•
If Call Policy mode is On but a policy has not been configured,
this shows you a default CPL script that allows all calls.
You may want to view the file to take a backup copy of the
Call Policy, or, if Call Policy has been configured using the
Call Policy rules page you could 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 recognize
the file and automatically add each rule back into the Call
Policy rules page.
