DHCP Server — A DHCP server must be configured to provide IP
addresses and additional information to VCX branch office servers and
PSTN Gateways when those devices request IP addresses. Before a
software upgrade is done on a branch office VCX server, the DHCP
configureation must be modified so that the server can properly
respond to updated identification information that the branch office
server will send.
This appendix provides guidance on how to configure two sample
DHCP servers:
■
Internet Systems Consortium (dhcpd)
■
Windows 2003 Server
Configuration Files
Configuration files are used to automate the configuration of the branch
office VCX server and the PSTN Gateway connection to the telephone
company’s central office equipment, also located in the branch office.
For instructions on how to create the configuration files, see these
descriptions:

Configuration Files
To create a configuration file for a branch office VCX server, run the
vcx-createcfg
script on any VCX server on which the target VCX
software version (the version to which you intend to upgrade the branch
office server) has been installed. The VCX server on which you run the
script can be configured as any one of the VCX configurations. It does
not need to be a branch office configuration.
To create the configuration file:
1 Log in as root on the server.
2 Enter this command:
vcx-createcfg
Running the
vcx-createcfg
script as described here does not disrupt the
normal operation of the VCX branch office server.
