1. A method for implementing a policy for a router, the method comprising: providing a meta administrator interface configured to facilitate specification of one or more rules that form a policy definition, wherein the meta administrator interface is configured to provide user interface elements for defining one or more conditions and one or more actions, wherein the one or more conditions includes an origin-based routing policy definition that includes a trigger point for triggering the origin-based routing feature and routing conditions associated with the origin-based routing feature, wherein the routing conditions include a source Internet protocol (IP) address and a method type of a session initiation protocol (SIP) message, wherein the routing conditions include a filter for identifying when to perform the one or more actions, and wherein the filter defines a SIP message attribute that is to be compared, a comparison operator, and a type of rule data for comparing to the SIP message attribute; automatically generating, based on the one or more rules that form the policy definition, an administrator interface for inputting rule data associated with the policy definition, wherein the administrator interface is configured to include conditions and actions defined using the meta administrator interface and to provide user interface elements for inputting rule data associated with the one or more conditions and the one or more actions, and wherein at least one of the user interface elements provided by the administrator interface is for inputting the rule databased on the type of rule data defined by the filter; and storing the rule data in one or more data structures associated with a router.
