About Policy Services; Policy Service Request Parameters - Cisco TelePresence Administrator's Manual

About policy services

Policy services are typically used in large-scale deployments where policy decisions can be managed
through an external, centralized service rather than by configuring policy rules on the VCS itself.
You can configure the VCS to use policy services in the following areas:
Registration Policy
n
Search rules (dial plan)
n
Call Policy
n
User Policy (FindMe)
n
More information about policy services, including example CPL, can be found in the
deployment guide.

Policy service request parameters

When the Cisco VCS uses a policy service it sends information about the call or registration request to the
service in a POST message using a set of name-value pair parameters.
The service can then make decisions based upon these parameters combined with its own policy decision
logic and supporting data (for example lists of aliases that are allowed to register or make and receive calls,
via external data lookups such as an LDAP database or other information sources).
The following table lists the possible parameters contained within a request and indicates with a ü in which
request types that parameter is included.
