Abstract
Methods, systems, and computer readable media for media session policy compliance auditing and enforcement using a media relay and session initiation protocol (SIP) signaling are provided. One method includes at a SIP policy server, receiving SIP signaling from a user agent client to obtain a policy for media session and, in response, generating at least one media session correlation token. At least a portion of the SIP policy server is implemented in hardware. The media session correlation token and the media policy are communicated to the user agent client and to a media relay. Identification information for the media relay is also communicated to the user agent client. At least a portion of the media relay is implemented in hardware. At the media relay, the media session correlation token is received and used to correlate and store usage information for the media session and to monitor compliance with the media policy.
