The Enterprise Voice, Video, and Messaging Session Manager must be configured to require Voice Video Endpoints to re-register at least every three hours.

Device registration is a solution enabling an organization to manage devices. It is an additional layer of authentication ensuring only specific pre-authorized devices can access the system. Registration is the process of authorizing endpoints to communicate with the session manager. Registration occurs with the SIP server in VoIP systems and with a gatekeeper in H.323 systems. Without enforcing registration, an adversary could impersonate a legitimate device on the Voice Video network.

Verify the Enterprise Voice, Video, and Messaging Session Manager requires Voice Video Endpoints to re-register at least every three hours.

If the Enterprise Voice, Video, and Messaging Session Manager does not require Voice Video Endpoints to re-register or does not enforce re-registration at least every three hours, this is a finding.
