Description
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.
