When using PKI-based authentication, the Voice Video Endpoint used for videoconferencing must implement a local cache of revocation data to support path discovery and validation in the event the network path becomes unavailable.

Description
Without configuring a local cache of revocation data, there is the potential to allow access to users who are no longer authorized (users with revoked certificates). This does not apply to authentication for the purpose of configuring the device itself (i.e., device management).
