Fix Recommendation

Implement and document the local Enterprise Voice, Video, and Messaging system with the capability to place intrasite and local phone calls when network connectivity is severed. The minimum capability for placement of line-side precedence calls depends on the C2 requirements of the site and must be determined in conjunction with the local command authority. To satisfy this requirement, at a minimum, ROUTINE call placement capabilities must be maintained.

If the local Enterprise Voice, Video, and Messaging system does not have the capability to place intrasite and local phone calls when network connectivity is severed, this is a finding.

Reliance on government-furnished equipment or personal cellphones does not meet this requirement because signal strength and reliability are reduced inside buildings, and cellphones are not permitted in most DOD facilities.

The minimum capability for placement of line-side precedence calls depends on the command and control (C2) requirements of the site and must be determined in conjunction with the local command authority.
