The Voice Video Session Manager must produce session (call) records containing the outcome (status) of the connection. (Cat II impact)

Discussion

Without the capability to generate session records, it is difficult to establish, correlate, and investigate the events relating to an incident, or identify those responsible. Session records are generated from several components within the Voice Video system (e.g., session manager, session border control, gateway, gatekeeper, or endpoints). 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.

Check Content

Verify the Voice Video Session Manager produces session records containing the outcome (status) of the connection. The outcome or status of a call includes call completed normally, busy endpoint, busy network, preempted, or other pertinent description. If the Voice Video Session Manager does not produce session records containing the outcome (status) of the connection, this is a finding.

Fix Text

Configure the Voice Video Session Manager to produce session records containing the outcome (status) of the connection.
