Unless otherwise noted, these features are available on the NBX 100,

CAUTION: The NBX telephone system is controlled by a computer system 
using a Local Area Network (LAN). Your telephone is connected to the 
system through an RJ45 Ethernet connection instead of a typical RJ11 
telephone connection. Your telephone will not work unless it is 
connected properly. Contact your administrator if you have questions 
about your telephone connection.
