The OCS zone must be inside any firewall; the endpoint receiving or making the call can be outside
n
the firewall.
The VCS shows calls routed via the Cisco AM GW as two calls: one from the endpoint via the VCS
n
to the Cisco AM GW which will be a local or traversal call as appropriate, and then a separate call
back from the Cisco AM GW via the VCS to the OCS which will always be a local call.
Bandwidth controls can be applied to the leg of the call between the endpoint and the Cisco AM GW
n
zone, but cannot be applied to the Cisco AM GW zone to OCS zone leg of the call.
For more information about configuring VCS, OCS and the Cisco AM GW, refer to the Microsoft OCS
2007, VCS and Cisco AM GW deployment guide [37].

Configuring Cisco AM GW policy rules

The Advanced Media Gateway policy rules page
Gateway > Policy
rules) lists the set of rules that control which calls can go through the Cisco AM
GW.
By default, after a VCS 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
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 you can click on a column heading to sort the list, for example by Rule name or
Priority.
The configurable options are:
Field
Description
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.
