Routing calls via the Cisco AM GW

Configuring Cisco AM GW policy rules

The Advanced Media Gateway policy rules page (VCS configuration > Advanced Media Gateway >
Policy rules) lists the set of rules that control which calls can go through the Cisco AM GW.
•
By default, after a VCS Control has been configured with the Cisco AM GW to use for OCS calls,
all calls to or from the OCS zone are routed via the Cisco AM GW.
•
The rules on this page are only applied if the Policy mode on the Advanced Media Gateway
configuration page is set to On.
•
A rule is applied if it matches either the source or destination alias of a call. Note that if the
aliases associated with a call do not match any of the policy rules, the call will be routed via the
Cisco AM GW.
The page lists all the currently configured rules and lets you create, edit, delete, enable and disable
rules. Note that:
•
Priority 1 rules are applied first, followed by all priority 2, and so on.
•
You can click on a column heading to sort the list, for example by Rule name or Priority.
•
If you hover your mouse pointer over a rule, the rule description (if one has been defined) appears
as a tooltip.
To configure Cisco AM GW policy rules using the CLI:
xConfiguration Services AdvancedMediaGateway Policy Rules
•
xCommand AMGWPolicyRuleAdd
•
xCommand AMGWPolicyRuleDelete
•
Enabling and disabling policy rules
When you are making or testing configuration changes to your Cisco AM GW policy rules, you may
want to temporarily enable or disable certain rules. You may also want to configure certain rules but
only apply them occasionally.
You can do this by selecting the rule's check box and clicking Enable or Disable as appropriate. Any
disabled rules still appear in the rules list but are ignored by the VCS when determining which calls
are routed via the Cisco AM GW.

Configuration options
The configurable options are:
Rule name
The name assigned to the rule.
Description
An optional free-form description of the rule.
Priority
Sets the order in which the rules are applied. The rules with the highest priority (1, then 2, then 3
and so on) are applied first. Multiple rules with the same priority are applied in configuration order.
Pattern type
The way in which the Pattern string must match either the source or destination alias of the call.
Options are:
Exact: the string must match the alias character for character.
Prefix: the string must appear at the beginning of the alias.
Suffix: the string must appear at the end of the alias.
Regex: treats the string as a regular expression.
Pattern string
Specifies the pattern against which the alias is compared.
Action
The action to take if the source or destination alias of the call matches this policy rule.
Allow: the call can connect via the Cisco AM GW.
Deny: the call can connect but it will not use Cisco AM GW resources.
State
Indicates if the rule is enabled or not.
Cisco AM GW policy rules support the use of Regular Expressions in the Pattern String field.
See the Regular expression reference
You can test whether a pattern will match a particular alias and be transformed in the
expected way by using the Check pattern
