14 CHAPTER 1: PRE-INSTALLATION GUIDELINES
During installation, specific software services may or may not be enabled
in a given software configuration. An example is the Call Records Service
which is designed to run on a single hardware platform. In the three
single office configurations, the Call Records Service is enabled on the
Primary IP Telephony and Messaging or Primary IP Telephony server only.

VCX systems require that each server in a regional office have both eth0
and eth1 configured. Branch office servers must have only eth0
configured. Single office systems are considered to be the same as
regional offices for this purpose.
CAUTION: For each regional server, both Network Interface Cards (NICs)
must be connected to only one subnetwork. However, if you configure
the primary regional server on one subnetwork, you can configure the
associated secondary server on a different subnetwork.
For regional servers, individual software services use either eth0 or eth1
as follows:
For branch servers, all software services use eth0.
