NET.4.2.A4 Restricting Accessibility via VoIP (B)

A decision MUST be taken as to how external callers will be able to access VoIP architecture. IT systems from insecure networks MUST be prevented from establishing direct data connections to an organisation's VoIP components. If all incoming and outgoing connections are to be handled via a central IT system, it SHOULD be ensured that all signalling and voice information between the public and private data networks in question is only exchanged via this authorised IT system.
