16 Voice over IP Quick Start Guide
This section explains how to configure FXS VICs. Ports on this VIC connect directly to a standard
telephone, fax machine, or similar device.
Figure 12 shows a basic voice network. A small business uses a Cisco 3600 series router (named
West) to provide telephone and fax connections among employees in its office. Figure 12 shows two
of these telephones, each connected to an FXS VIC port in the West router.

Note You can name your router by using the hostname command in global configuration mode.
Table 1 lists telephone numbers and voice ports for the West router. (For information about port
numbering, see the section on “Voice Port Numbering” earlier in this guide.)

Note Additional telephones and fax machines could be connected in this example, up to a total of
12 if the router is a Cisco 3640 configured with three two-slot voice network modules. The module
in the remaining slot would provide interfaces for IP connectivity to the LAN or WAN and for data
traffic. To accommodate more than 12 voice devices, you would need to add more routers, or to use
an E&M VIC and a local PBX, rather than connecting every telephone to its own FXS VIC.
