Title

The Voice Video Endpoint must produce session (call detail) records containing the outcome of the connection. (Cat II impact)

Discussion

Session records are commonly produced by session management and border elements. Many Voice Video Endpoints are not capable of providing session records and instead rely on session management and border elements. Voice video endpoints capable of producing session records provide supplemental confirmation of monitored events. Voice video endpoints that communicate beyond these defined environments must generate session records. Session record content that may be necessary to satisfy this requirement includes, for example, type of connection, connection origination, time stamps, outcome, user identities, and user identifiers. Additionally, an adversary must not be able to modify or delete session records. Detailed records are typically produced by the session manager but can be augmented by non-telephone endpoint records.

Check Content

If the Voice Video Endpoint relies exclusively on the Voice Video Session Manager for session records and does not have any capability for generating session records, this check procedure is Not Applicable. Verify the Voice Video Endpoint produces session records containing the outcome of the connection. Outcomes of the connection would include call completed, conference completed, destination busy, network busy, etc. If the Voice Video Endpoint does not produce session records containing the outcome of the connection, this is a finding.

Fix Text

Configure the Voice Video Endpoint to produce session records containing the outcome of the connection.
