Depending on the hardware configuration, some services are typically
installed in redundant pairs. For example, the Call Processor Service is
designed to run on redundant servers so if the primary server fails, the
secondary server can take over processing.
However, during installation, specific software services may or may not be
enabled in a given software configuration. For example, the Call Records
Service is designed to run on a single hardware platform. In single-site
configurations, the Call Records Service is enabled on the primary IP
Telephony and Messaging or primary IP Telephony server only. In a
multi-site system, the Call Records Service is typically enabled on a
dedicated server.
This section briefly describes the basic hardware configurations that
support VCX systems. Refer to the VCX Installation Guide for more
information. Because VCX system software can be installed in a wide
variety of hardware configurations, you must understand how your VCX
system has been installed before you configure its components.
