Mixed Network
When using the NDSS feature over a mixed network containing both VoIP portions and ISDN line portions,
it is possible to set whether status information will be transferred between VoIP and ISDN cards within
each PBX. For example, if the monitor PBX is on a VoIP network, and monitored PBXs are on an ISDN
