External Policy Request Parameters - Cisco TelePresence Administrator's Manual

Reference material
More information about policy services, including example CPL, can be found in the
Deployment Guide.

External policy request parameters

When the 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 service response must be a 200 OK message with CPL contained in the body.
The following table lists the possible parameters contained within a request and indicates with a ü in which
request types that parameter is included. It also indicates, where relevant, the range of accepted values.
