This makes it possible to have only one IP packet-switched network for both computer and phone services. It seems that for example NSA's NSTS phone system is now fully IP-based. An old NSTS telephone and a KVM-switch which enables switching between physically separated networks, in this case two Unclassified (green labels), one Secret (red label) and one Top Secret/SCI (orange and yellow label) network (Natio...
