Changes: Policy Framework Draft Token in Policy-Id header parameter: UAs copy tokens received from the policy server into the Policy-Id header. Can be used to route all requests for setting up a session to same proxy. Usage of policies: UA compliant to this spec MUST use policies received or, if it decides not to accept them, reject/terminate the session. Policy usage was SHOULD. A UAS that does not accept policies MUST reject session with 488. Clarified procedure for terminating sessions. Clarified that local policy server URI can be received via configuration. Added descriptive text to example in 4.3.2 Security section discusses that a policy server may encounter UAs it cannot authenticate. Editorial changes. |
