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
Configuring Call Policy to use an external service [p.197]
.
Configuring Call Policy rules using the web interface
The
Call Policy rules
page (
Configuration > Call Policy > Rules
) lists the web-configured (rather than
uploaded via a CPL file) Call Policy rules currently in place and allows you to create, edit and delete rules. It
provides a mechanism to set up basic Call Policy rules without having to write and upload a CPL script.
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 (
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.
Each rule specifies the
Action
to take for all calls from a particular
Source
alias to a particular
Destination
alias. If you have more than one rule, you can
Rearrange
the order of priority in which these rules are applied.
If rules are not configured, the default policy is to allow all calls, regardless of source or destination.
The configurable options are:
Field
Description
Usage tips
Source
pattern
The alias or IP address 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:
n
locally registered and authenticated with the VCS, or
n
registered and authenticated to a neighbor which in turn has authenticated
with the local VCS

Destination
pattern
The alias or IP address that the endpoint dialed to make the call.
This field supports

.
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.
Click on the rule you want to configure (or click
New
to create a new rule, or click
Delete
to remove a rule).
Configuring Call Policy using a CPL script
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. However, due to the complexity of writing CPL
