Configuring IP Telephony 183 RFC 2132 (DHCP Options and BOOTP Vendor Extensions) defines vendor specific options that allow you to configure the server to send locally defined information to DHCP clients. NBX system devices support option 184. If you create and activate option 184 on your DHCP server, and use it to specify the IP address of the NCP, you do not need to manually configure the address on the NBX devices. For an example of how to configure a DHCP server for option 184, see Appendix C, "Configuring Option 184 on a Windows 2000 DHCP Server" in the NBX Administrator's Guide.
